Vetted waterproofing specialists in Benoni. Book now.

Budget around R180 to R350 per m² for a liquid membrane and R250 to R450 per m² for torch-on in Benoni, with materials included. The price climbs if old waterproofing has to be stripped or the screed needs falls built in. Ask for the labour, materials and guarantee period on the quote.

It depends where the water comes from. Roof and parapet leaks are fixed with waterproofing, but rising damp from the ground needs a damp-proofing treatment instead. A specialist should check which one you have before quoting, as the fixes are very different.

Pitched tiled roofs shed water by design, so they rarely need a full membrane, but flashings, valleys and ridge joints often do need sealing. Flat concrete roofs, balconies and parapets are where proper waterproofing systems matter most. A specialist will tell you which parts are the actual risk.

A typical house roof of 50 to 100 m² takes two to four days, including cleaning, repairs, priming and the membrane itself. Liquid systems need drying time between coats, and rain stops work entirely. Ask for a schedule that keeps the roof covered if weather turns.
