A concrete flat roof is a great structure, as it is a life time product. It is a structure that must have a waterproofing system that is manufactured specifically for this purpose, as often due to the slight degree in the roof, water can collect on the roof and stay there for long periods, and that is why a torch-on system is fitted, as water will not effect the product.

A Torch-on system is applied to a concrete roof. A Concrete roof repair is often necessary because concrete is susceptible to scaling, cracking, crazing, spalling, and a host of other issues with regular wear and tear. In most cases, minor, timely repairs and regular maintenance will ensure that there is no structural damage.

This Torch-on system is fitted by qualified SA Waterproofing personal, who apply the torch-on system by a heat fusion technique. This system is maintained by applying silver aluminum coat of paint to protect the product from the UV rays.

Our service is applied on flat and concrete roofs, and building foundations.
