Concrete Roof Slab Waterproofing in Meyerton

Location: Meyerton, Gauteng
Service: Concrete Roof Slab Waterproofing (ArmTec HyperFlex System)

When a flat concrete roof slab starts to leak, the damage rarely stays on the roof. It works its way down through the ceiling and shows up on the walls of the rooms below. That is the pattern behind almost every slab call-out SealAll Roof Contractors handles across the Vaal: old waterproofing that has reached the end of its life and needs a full remedial overhaul rather than another patch.

The problem

On a typical failing slab, the existing waterproofing membrane has delaminated and cracked across large sections of the roof. Years of sun exposure, thermal movement and standing water lift the old coating away from the concrete, leaving weathered, spalling surfaces and open cracks at the joints and parapet junctions. Water tracks under the failed membrane and into the structure, with damp showing up on interior walls and around window and door reveals in the rooms below. Every affected area of the slab, from bedrooms to sculleries, garages and chimney upstands, tends to show the same tired, failing coating.

The SealAll Roof Contractors solution

As an approved SealPro applicator, SealAll Roof Contractors strips the project back to sound substrate and rebuilds the waterproofing as a single monolithic system:

1. Prepare and prime. Every square metre of the slab is cleaned back, loose material removed and the concrete primed with Penetrar to lock down the surface and give the new system a solid key.
2. Reinforce the weak points. Cracks, delaminated joints and parapet junctions are bridged with StretchSeal membrane, sealing the exact spots where movement has opened the old coating.
3. Install the ArmTec system. A HyperFlex base coat is applied and ArmTec reinforcing mesh embedded into it, then over-coated to create a seamless, fully bonded and elastic waterproof layer across the whole slab.
4. Seal the details. Roof vents, pipe penetrations and parapet upstands are carefully worked in so there are no gaps left for water to find.
5. Top coat and protect. The system is finished with HydroSeal HF and sealed with a clear protective coat, leaving a clean, UV-stable grey surface that reflects heat and sheds water.

The result

The roof ends up with a continuous, flexible waterproofing skin that moves with the building instead of cracking against it. Valleys drain cleanly, penetrations stay sealed and interior damp problems are cut off at their source. Backed by a workmanship guarantee and SealPro’s manufacturer warranty, a slab treated this way is set up for many dry seasons ahead.

If your flat roof or concrete slab is leaking, delaminating or staining the ceilings below, the sooner it is assessed the less it costs to fix. SealAll Roof Contractors is an approved SealPro applicator serving Vereeniging, Meyerton and the greater Vaal region.
