Flat Roof & Slab Waterproofing – Roodepoort & West Rand

Reliable Waterproofing for Concrete Roofs, Balconies & Slabs

If you have a flat concrete roof or slab that's leaking or holding water, it's important to act before further damage sets in. Water ingress on slabs can lead to damp ceilings, peeling paint, mold, and eventually structural issues.

At Environmental Pro Construction, we offer honest, engineered waterproofing solutions, no shortcuts, no pressure.
Every inspection is free and includes professional advice tailored to your roof type and environment.
