Concrete Roof Slab Waterproofing in Meyerton
Location: Meyerton, Gauteng
Service: Concrete Roof Slab Waterproofing (ArmTec HyperFlex System)
Flat concrete roof slabs are common on homes, blocks of flats and commercial buildings around Meyerton, and every one of them eventually reaches the end of its waterproofing life. In this case study, the roof slab had cracked along shrinkage joints, the surface coating had delaminated and worn away, and the building below was no longer protected from water. The owner brought in SealAll Roof Contractors to strip the roof back, repair every movement point and install a full reinforced waterproofing membrane over the entire slab.
As an approved SealPro applicator, SealAll Roof Contractors installs the complete SealPro ArmTec HyperFlex waterproofing system — the correct primer, crack reinforcement, embedded mesh and topcoat, applied in the correct sequence, so the finished membrane bridges movement instead of splitting open again.
The problem: a cracked, delaminated concrete roof slab
Flat concrete roofs live or die on their ability to move without cracking. On slabs like this one, the concrete opens up along shrinkage cracks and construction joints over time, and the original surface coating delaminates and weathers away. Debris and standing water collect on the roof, and every crack becomes a direct path for water into the ceilings and structure below. Left untreated, a failed slab leads to damp, spalling concrete, rusting reinforcement and ongoing interior damage.
The solution: the SealPro ArmTec reinforced membrane system
Our waterproofing team worked through the proven SealPro ArmTec sequence for concrete slabs:
- Clean and prepare — the full slab was cleared of debris, loose material and standing water, then cleaned back to a sound, stable surface.
- Prime — the slab was primed with Penetrar, SealPro’s deep-penetrating primer, to bind the concrete and lock down porosity before any waterproofing layer went on.
- Reinforce the cracks and joints — every crack, delaminated joint and movement point was treated with Flex and StretchSeal membrane, sealing and bridging the roof’s weakest points first.
- ArmTec mesh membrane — a coat of HyperFlex was applied and ArmTec reinforcing mesh was rolled into it across the full surface, then encapsulated with a second HyperFlex coat, creating one continuous reinforced membrane that flexes with the slab instead of cracking with it.
- Topcoat — the system was finished with HydroSeal HF waterproof topcoat, delivering a clean, seamless, UV-resistant surface across the entire roof.
The result: a fully sealed, seamless flat roof
The finished slab is now a single, continuous waterproof membrane — no exposed cracks, no open joints and a clean, uniform finish from edge to edge. The building is protected against Highveld summer storms, and the reinforced ArmTec system is built to move with the structure for the long term. Every SealAll Roof Contractors project is backed by our workmanship guarantee and a warranty certificate on completion.

Roof & Balcony Slab Waterproofing in Vereeniging
Location: Vereeniging, Gauteng
Service: Roof Slab & Balcony Slab Waterproofing (ArmTec HyperFlex System)
This case study looks at a double-storey home with two exposed concrete slabs working against it: a flat roof slab and an upstairs balcony slab, both structurally sound but neither properly sealed against summer downpours. With turnups, outlets, and slab edges left vulnerable, it was only a matter of time before water found its way in. A SealPro-approved applicator was brought in to waterproof both slabs before the damage could spread into the structure below.
The problem the homeowner was facing
Standing water was already pooling against the parapet wall at roof level, sitting for long enough to leave dark staining and silt across the slab surface. Around the turnups and outlets — the weak points where water pressure concentrates first — the substrate had no membrane protection at all. On the balcony slab, the same risk existed one floor down, directly above living space, where a slow leak is far harder to spot until it shows up as a stain on a ceiling. Left untreated, both slabs would have continued absorbing moisture through hairline cracks and unsealed joints, risking damp patches, reinforcing steel corrosion, and costly interior repairs.
The waterproofing solution
The crew approached both slabs with the same disciplined sequence, using the ArmTec waterproofing system as an approved SealPro applicator:
- Prep and prime the substrate — the roof and balcony slabs were cleaned back to a sound surface and primed to give the waterproofing membrane a surface it could properly key into.
- Strengthen turnups and outlets — every turnup and outlet was reinforced with a stretch-seal membrane, closing off the exact points where roof leaks typically start.
- Apply the ArmTec waterproofing system — a fibre-reinforced membrane was rolled out across the full roof slab and balcony slab, tying the parapet turnups into a single, continuous waterproof layer.
- Finish the balcony with a tile-ready topcoat — since the balcony doubles as a walked-on surface, a tile-ready topcoat was applied over the membrane, giving it a durable, textured finish ready for foot traffic or tiling.
The result
Both slabs now carry a continuous, reinforced waterproof membrane from the parapet edges right across the deck, with the balcony finished in a tough, tile-ready surface that can take daily use. The ponding and staining that had built up at the roof edge is gone, and the turnups and outlets — the areas most likely to fail first — are fully sealed. The homeowner now has two fully protected concrete slabs backed by manufacturer warranty on the ArmTec system.
If your home has an exposed roof slab or balcony that’s showing ponding, staining, or damp patches on the ceiling below, don’t wait for it to become a structural repair. SealAll Roof Contractors is an approved SealPro applicator serving Vereeniging and the greater Vaal Triangle.

Roof Slab Waterproofing in Sasolburg
Location: Sasolburg, Free State
Service: Roof Slab Maintenance & Waterproofing
A flat concrete roof slab had reached the end of its waterproofing life. Years of UV exposure and thermal movement had taken their toll, and the existing membrane was no longer keeping water out. An approved SealPro applicator was brought in to strip back the failed system and reinstate a durable, fully bonded waterproofing layer across the entire roof deck.
The problem
On inspection, the roof showed several classic signs of an ageing waterproofing system nearing failure. The existing membrane had delaminated and cracked in multiple areas, breaking the waterproof seal, while joints and laps were separating and creating open pathways for water ingress. Water was puddling in front of several outlets — a sign that drainage falls had degraded and water was no longer running off as designed. The coating had also lost its UV protection, leaving the substrate underneath exposed and vulnerable, and flashing details at the parapet walls and upstands were deteriorating, with cracked cement fillets and lifting edges. Left unaddressed, this combination of failed joints, ponding water and UV-degraded coating would have led to water tracking into the slab itself, risking damage to the structure and the ceilings below.
The solution
The applicator specified a SealPro flat-slab waterproofing system built for exactly this kind of failed, aged concrete deck. The remedial process covered the full roof slab and followed these steps:
- Strip and prepare the substrate — All loose, cracked and delaminated sections of the old membrane were removed, along with any debris and contamination, to expose a sound working surface.
- Repair joints and details — Cracked joints, parapet upstands and outlet surrounds were repaired and detailed before any coating went down, closing off the points where water had been getting in.
- Prime the substrate — A bonding primer was applied across the full roof area to promote adhesion and seal the porous concrete surface.
- Apply the waterproofing system — The membrane was rolled on in overlapping bands to build an even, fully bonded, seamless waterproof layer across the whole slab, including any adjoining sections tied into the same roof structure.
- Quality control and finish — Each section was checked for full coverage and consistent thickness before moving on, with drainage points, pipe boots and upstands finished off last to complete the waterproof seal at every detail.
The result
The roof now carries a continuous, UV-stable membrane with no open joints, no delaminated patches, and correctly sealed drainage points and flashing details. The ponding that had been forming in front of the outlets is gone, and the roof is protected against the sun and rain for years to come, backed by the standard manufacturer warranty on the system.
This is the kind of slab failure we see on older flat-roof properties throughout the region: a membrane that’s quietly cracked, delaminated or lost its UV protection long before a leak shows up on the ceiling below. SealAll Roof Contractors is an approved SealPro applicator serving Vereeniging, Sasolburg and the greater Vaal region, bringing the same strip, repair, prime and waterproof process to every slab roof job we take on.

Roof Slab Waterproofing in Johannesburg South
Location: Johannesburg South, Gauteng
Service: Roof Slab Waterproofing
This case study looks at a flat concrete roof slab where the original waterproofing had reached the end of its service life. Large sections of the coating had delaminated and cracked, and water was already tracking through to the ceiling below. The property owner called in SealAll Roof Contractors to strip the failed system back and rebuild a proper, watertight roof from the substrate up.
The problem: cracked, delaminated waterproofing
On inspection, the existing waterproofing was clearly failing. Large sections had lost adhesion to the slab, and hairline cracks had opened up along the expansion joints, widening enough to let water track straight through the concrete. The signs were visible in more than one place:
- Delaminated, cracked coating across the main slab, with staining where water had been sitting and evaporating through the surface
- Open, separating joints where the membrane had lost its bond
- A stained ceiling inside the property, marking exactly where water had found its way through from above
Left unattended, cracks like these only get worse with every summer storm and every cycle of heat and cooling on an exposed slab.
The SealAll solution
As an approved SealPro applicator, SealAll Roof Contractors specified a slab waterproofing system built specifically for flat concrete roofs like this one. The team worked through the following steps on site:
- Substrate preparation – Cleared and prepared the slab, removing all failed coating and loose material back to a sound surface.
- Priming – Primed the full slab area to lock down the concrete and give the new system a proper key.
- Crack and joint reinforcement – Bridged and strengthened every crack and delaminated joint with a reinforcing membrane, closing off the points where water had been getting in.
- Monolithic waterproof coating – Applied the waterproofing system across the entire slab as a continuous, seamless layer, working the coating up and around all roof detailing.
- Roof fixture reinstatement – Lifted and reinstalled roof-mounted fixtures so the new waterproofing ran unbroken beneath them, with no gaps left around the bases.
The result
The slab now carries a single, continuous waterproofing layer with no weak joints or cracked patches left exposed. Every corner, upstand and parapet detail was sealed as part of the same system, and roof fixtures were reinstated onto a fully waterproofed base rather than left sitting on old, failing coating. The property now has a roof slab that sheds water reliably, with the leak that was staining the ceiling below fully resolved.
Flat concrete slabs across the Vaal region face the same combination of thermal movement, UV exposure and seasonal rain that caused this damage, which is why regular slab inspections are worth building into any maintenance schedule.

Flat Roof Slab Waterproofing & Drainage Repair in Vanderbijlpark
Location: Vanderbijlpark, Gauteng
Service: Flat Roof Slab Waterproofing with Outlet Repositioning
Flat concrete roof slabs are common on double-storey homes across the Vaal, and they work well — as long as water is draining off them, not pooling on them. On one recent case study, a large flat slab sitting directly above a bedroom and bathroom had two old drainage outlets positioned at a low point on the roof instead of the edge. Rather than shedding rainwater quickly, the slab was holding it, and a slow leak had started tracking down into the ceiling below during heavy Highveld storms.
The problem
From a distance, the roof looked fine — a smooth grey membrane with a tidy cable run across it. Up close, it told a different story. The original full-bore outlet had been let into the slab at a point that collected standing water rather than draining it, and years of ponding had worn straight through the surrounding waterproofing. Around the outlet, the membrane had cracked and lifted, leaving a dark, water-stained hole down into the substrate. Every rain event was pushing moisture past the failed seal and into the rooms below.
This is one of the most common — and most overlooked — causes of flat roof leaks: it’s rarely the membrane itself that fails first, it’s outlets and drainage points placed where water naturally collects instead of where it can escape.
The solution
Working as an approved SealPro applicator, the crew followed a sequence built to fix the drainage problem permanently rather than patch the symptom:
- Close and rescreed the old outlet. The failed full-bore outlet was sealed off and the surrounding slab rescreeded back to a sound, level surface, removing the low point that had been collecting water in the first place.
- Reposition drainage to the outer wall. Two new 80 mm outlets were installed on the outer wall, moving the discharge point to where water could shed efficiently instead of pooling in the middle of the roof.
- Prep and prime the full substrate. The entire slab — roughly 35 m² — was cleaned, degreased and primed to give the new waterproofing system a clean, stable base to bond to.
- Apply the ArmTec waterproofing system. A flat-slab ArmTec membrane was applied across the full area, reinforced at the new outlet points and roof edges where water movement is greatest.
The result
The slab now drains cleanly to the two new outer-wall outlets instead of pooling in the middle of the roof, and the ArmTec system leaves a durable, seamless waterproof layer with no weak points around the drainage. The rooms below are protected from the kind of slow leak that can go unnoticed for months, and the roof is finished with a clean, uniform coating built to handle a full Highveld storm season.
If your flat roof slab is showing similar signs — ponding water, a stained ceiling, or outlets that never seem to keep up with heavy rain — the fix is rarely the membrane alone. It’s usually the drainage layout underneath it.

IBR Metal Roof Waterproofing & Repaint in Alberton
Location: Alberton, Gauteng
Service: IBR Metal Roof Waterproofing & Painting
Steel IBR roofs are tough, but the coating and the fixings are where they age fastest. In this case study, an IBR sheeted roof had reached the end of its original coating life after years of sun, rain and thermal movement. The sheeting had weathered badly, rust was creeping in along the overlaps, and the screw lines had become the weak points where water could track through. The brief was simple: bring the roof back to a fully sealed, watertight, good-looking condition without a full replacement.
The problem
IBR profile sheeting is durable, but it lives or dies on its coating and its fixings. On this roof the paint had faded and chalked, exposing bare metal that was already showing rust bloom along the raised ribs and side laps. The self-tapping screws had loosened slightly over time, and the old sealant washers had perished, so every screw line was a potential leak path. Left untreated, that corrosion spreads under the coating and the joints keep opening up — a proper strip-back, treatment and re-seal was the only lasting fix.
The solution
As an approved SealPro applicator, the crew followed a full metal-roof remediation system rather than simply repainting over the problem:
- Access and prep. Any adjacent tiled sections were carefully lifted and stacked so the full IBR area could be worked, then the entire roof was high-pressure washed and degreased back to a sound surface.
- Rust treatment. All rusted sections were mechanically cleaned, treated with a rust converter and primed with Purple Prime to lock down the metal and give the coating system a stable base.
- Seal the weak points. Overlaps, joints and every screw line were reinforced with Flex and StretchSeal, and the fixings sealed with ScrewSeal, closing off the paths where water had been getting in.
- Waterproof membrane. HydroSeal HF was applied over the prepared and sealed sheeting to form a continuous, flexible waterproof layer that moves with the roof.
- Finishing coats. Two coats of high-quality roof paint were applied for a uniform, UV-stable finish, and the gutters were cleaned and waterproofed to complete the drainage.
The result
The roof now reads as a single clean, uniform plane — sealed overlaps, protected screw lines and a fresh, durable coating from ridge to eaves. The rust has been stopped and encapsulated, the leak paths are closed, and any reinstated sections tie the roofscape back together neatly. The outcome is a watertight, low-maintenance IBR roof built to give many more years of reliable service before it needs attention again.

Commercial IBR Metal Roof Waterproofing in Vereeniging
Location: Vereeniging, Gauteng
Service: IBR Metal Roof Maintenance & Waterproofing (Commercial)
A large commercial IBR sheet-metal roof had reached the point where its original coating was breaking down. The owner needed the roof stripped back to sound metal, every leak path sealed, and the whole surface re-coated so the building was protected and looking sharp again — a job carried out across the full roof, plus remedial work to the surrounding walls.
The problem: rust, failing overlaps and worn coating
Years of sun, wind and rain had taken their toll on the IBR sheeting. Rust had broken through along ridge caps, sheet overlaps and around screw fixings, spreading in tell-tale orange streaks down the pans. The old coating had chalked and thinned, several joints and screw lines were no longer watertight, and moisture was tracking into the structure. Left unattended, corrosion like this eats through metal sheeting and turns a maintenance job into a full re-sheet.
The solution: a full remedial coating system
Following a proven metal-roof remedial sequence:
- High-pressure clean and degrease the entire roof to strip chalk, dirt and loose material back to a sound surface.
- Treat all rusted sections with a rust converter to neutralise corrosion, then spot-prime the bare metal with a purple metal primer.
- Seal every overlap, joint and screw line — the primary leak paths — bedding a flexible reinforcing tape into the seams and capping each fastener with a dedicated screw-seal compound.
- Apply a high-build waterproofing membrane across the treated areas to lock everything in as one continuous, flexible skin.
- Finish with two coats of high-quality roof paint for UV protection, a uniform colour and long service life.
Scaffold-tower access and a full health-and-safety file kept the crew working safely at height throughout, and the adjoining walls were prepped and repainted to match.
The result: a sealed, protected roof built to last
The finished roof is watertight, corrosion-free and finished in a clean, uniform coat that lifts the whole building. Overlaps, ridges and screw lines are sealed, the rust is gone, and the client has a durable coating system with a workmanship guarantee behind it — turning a deteriorating roof back into a low-maintenance asset for years to come.
This case study reflects the standard remedial process used on rusted IBR and metal roofs across the region — the same system applied on request in Vereeniging and surrounding areas.

IBR Metal Roof Rust Treatment & Waterproofing in Johannesburg South
Location: Johannesburg South, Gauteng
Service: IBR Metal Roof Rust Treatment, Waterproofing & Painting
This case study looks at a residential property with a large IBR (corrugated metal) roof that had gone years without maintenance. What started out as a straightforward repaint turned into a full rust-treatment and waterproofing job once the crew got up on the roof and saw the true condition of the sheeting.
The problem with the roof
From ground level the roof looked tired but manageable. Up close it was a different story. Large sections of the IBR sheeting had corroded down to a deep orange-brown, with the protective coating gone in places and rust breaking through the metal along the ribs and overlaps. The screw fixings and joint lines were the worst-affected areas — exactly where water finds its way in first — and a few pipe penetrations and gutter-box junctions had failing old sealant letting moisture track behind the brickwork. Left untreated, active rust like this doesn’t stay cosmetic for long: it eats through the sheeting and turns into leaks and structural replacement costs.
The SealAll solution
SealAll Roof Contractors, an approved SealPro applicator, followed a proper rust-remediation sequence rather than just rolling paint over the problem:
- High-pressure wash – The full roof area was stripped of loose scale, chalking and surface contamination before any product touched the metal.
- Rust conversion – Every corroded section was treated to chemically neutralise the active rust so it couldn’t keep spreading under the new coating.
- Waterproofing the overlaps, joints and screw lines – The highest-risk points on any IBR roof were sealed with a reinforced waterproofing system, embedding fibre mesh into the coating over each screw head and rib joint for a durable, flexible seal.
- Priming – The prepared sections were primed to give the topcoat proper adhesion and long-term rust resistance.
- Two coats of a high-quality roof paint system – This gave the sheeting a uniform, weather-resistant finish that reflects heat and sheds water instead of trapping it.
- Painting the gutters, fascias and pipe penetrations to match – The roof-edge detailing was finished as one consistent system rather than a patched-together repair.
The result
The rusted sections of sheeting are now sealed and neutralised instead of actively corroding, every screw line and overlap on the roof has a waterproof barrier built into it, and the gutter and edge detailing are cleanly coated and weather-tight. It’s the difference between a roof that’s merely been painted over and one that’s actually been treated at the source of the problem — which is what keeps a maintenance repaint from needing to be redone again in two years.
Metal roofs across the greater Vaal region face the same combination of intense summer sun, hail and seasonal storms that caused this damage, which is why catching rust early with a proper conversion-and-waterproofing sequence is far cheaper than waiting for a full re-sheet.

Multi-Section Metal Roof Waterproofing in Vanderbijlpark
Location: Vanderbijlpark, Gauteng
Service: Multi-Section Metal Roof Waterproofing & Painting
This case study looks at a large corrugated IBR metal roof made up of several distinct sections — a solar panel roof, a flat waterproofed section, and a separate side roof — where years without maintenance had let rust take hold and an old membrane crack and fail. It walks through the process used to bring a roof like this back to a single, watertight system, and it’s the kind of job SealAll Roof Contractors handles regularly across the Vaal.
The problem: rust, failed seals and a cracked membrane
On the main IBR sections, the factory paint had worn through along the ridges and screw lines, exposing bare metal to rust that was spreading across large areas of sheeting. The overlaps and screw fixings were no longer sealed, leaving multiple points where water could get in during heavy rain. On the flat section of the roof, the old waterproofing membrane had cracked and crazed across its surface, with patchy repairs visible where previous leaks had been dealt with piecemeal instead of properly resolved. With solar panels already mounted on one section of sheeting, any further delay risked turning routine maintenance into a much bigger job around fixed installations.
The solution: a full-system metal roof restoration
As an approved SealPro applicator, SealAll Roof Contractors follows a proven sequence for jobs like this:
- High-pressure wash and degrease the roof sections to strip away chalking paint, grime and loose debris ahead of treatment.
- Rust conversion on all corroded sheeting, stopping the spread of corrosion before it can undermine the new coating.
- Waterproof every joint, overlap and screw line across the IBR sheeting with a hand-applied elastic waterproofing coating at each vulnerable fixing point.
- Re-waterproof the flat roof section with SealPro HyperFlex, embedding fibreglass reinforcing mesh into the coating across the full surface and up every upstand for a seamless, crack-bridging membrane.
- Prime the metal roof surface ahead of topcoating, giving the paint system a properly bonded base.
- Apply two coats of premium roof paint across the remaining sheeting, restoring a uniform, low-sheen finish.
The work is typically carried out over several visits, moving section by section so the waterproofing on any flat areas can cure fully before recoating, while the metal sheeting is treated and painted in parallel.
The result: one roof, not three ageing sections
The finished roof presents as a single, cohesive system instead of separately failing sections. The rusted screw lines and overlaps are sealed and repainted in a clean, uniform finish, any solar installation sits on a roof that’s properly protected around its mountings, and the flat section carries a fresh, fully reinforced waterproofing membrane in place of the cracked surface that was there before. It’s the kind of full-roof maintenance that closes off every entry point for water at once, rather than chasing leaks section by section as they appear.
Whether your metal roof is a single simple span or a multi-section system with solar panels and flat areas mixed in, the same process applies. SealAll Roof Contractors is an approved SealPro applicator serving Vereeniging, Vanderbijlpark and the greater Vaal region.

Tile Roof Prep, Ridge Waterproofing & Paint in Vanderbijlpark
Location: Vanderbijlpark, Gauteng
Service: Tile Roof Prep, Ridge Waterproofing & Painting
A tile roof’s colour coat is its first line of defence, and once that layer gives out, the tiles themselves start absorbing water instead of shedding it. That was the situation on this tiled roof, where years of sun exposure had stripped the original blue-green finish back to a chalky, faded shell and cracked open several sections of the ridge line. The owner brought in a SealPro-approved applicator to reseal the ridges, recoat the full tiled roof, and replace the ageing barge board edging while they were at it.
The problem
The protective top coat on the tiles had failed almost everywhere, leaving patches of bare, porous concrete exposed to the weather. Along the ridge, the cement fill between capping tiles had cracked and, in several spots, crumbled away completely, opening gaps at the highest point of the roof where wind-driven rain does the most damage. The existing colour had also faded and patched unevenly across the roof planes, so the home was losing both protection and kerb appeal at the same time. The over-tile barge boards running along the roof edge had weathered along with everything else and needed replacing rather than repainting.
The solution
As an approved SealPro applicator, the team worked through a full prep-and-recoat sequence rather than painting over the existing damage:
- Ridge repair first. The loose, cracked cement fill along every ridge run was raked out back to sound material, the substrate was prepped and primed, and the joints were rebuilt and waterproofed with a stretch-seal system — locking down the most vulnerable line on the roof before any paint went on.
- Full roof clean and prep. The entire tiled roof, main house and outbuilding sections alike, was high-pressure washed to strip years of chalking, algae and loose coating back to a stable surface that new paint could actually bond to.
- Two-coat repaint. With the roof clean, dry and sound, the team applied SealPro’s M22 Ultimo Roof Paint in Slate in two full coats, working with the tile profile and roof pitch to build an even, durable film from ridge to eaves.
- Barge board flashing. The old over-tile barge boards were stripped off and replaced with new flashings along the roof edge, finished to match the new roof colour and closing off the last exposed edge on the job.
The result
The roof went from a patchy, faded blue-green to a clean, uniform slate grey that reads sharp against surrounding red-tile roofs. The ridges are sealed and tidy, the new edge flashings finish the roofline properly, and the tiles are shedding water again instead of soaking it up. It’s the kind of job that does not just look better from the driveway — it takes a roof that was actively letting water in at the ridges and puts a proper stop to it.
