What is Torch-On Waterproofing?
Torch-on waterproofing is a premium, multi-layered system designed specifically for flat or low-pitched structures prone to water pooling. It utilizes a durable bitumen membrane that is professionally fused to the surface using a high-temperature propane torch, creating a seamless, completely impermeable barrier against water.
Flat Roofs & Slabs
Ideal for residential concrete roofs, commercial complexes, and office parks where traditional roofing sheets cannot be used.
Balconies & Terraces
Applied beneath tiles or final screeds to ensure outdoor entertainment areas never leak into the rooms below.
Retaining Walls
Sealed externally to block lateral damp and groundwater from seeping into basement walls or subterranean structures.
Why Choose Torch-On Membranes?
100% Watertight
The thermal fusion process melts the seams together, eliminating the gaps where traditional sealants fail.
UV Resistant
Built to withstand intense South African heat and rapid temperature drops without cracking.
Highly Flexible
Accommodates the natural expansion and contraction of concrete structures without tearing.
10-Year Guarantee
Backed by a long workmanship guarantee, making it a highly cost-effective investment.
The Prop Seal Torch-On Process
Preparation
We strip away old, failing waterproofing systems and deeply clean the underlying concrete substrate.
Priming
A high-penetration bituminous primer is applied to ensure maximum adhesion for the membrane.
Torching & Seaming
Our qualified team torches the membrane down, overlapping the seams by a minimum of 100mm to guarantee zero weak spots.
UV Protection Coating
We finish the system with a protective silver bitumastic coating to reflect UV rays and extend the life of your seal.
