Concrete & Slab Waterproofing in Bloemfontein
Concrete is porous and lets water through over time. Balconies, exposed slabs, basement walls and concrete roofs all need proper waterproofing membrane systems to stay dry. We assess the substrate, repair any cracks first, then apply the right system for long-term protection.

Frequently Asked Questions
What is the difference between a torch-on membrane and a liquid membrane?
Torch-on (bitumen) membranes are applied with heat and are very durable for large flat areas. Liquid membranes are painted on and are better for detailed areas with penetrations and complex shapes. We recommend the right system after assessing the surface.
Can you waterproof a leaking basement in Bloemfontein?
Yes. We use negative-side (crystalline) waterproofing systems that work from inside, which is often the only practical option for an existing below-ground structure.
