Roof & Balcony Waterproofing Systems
Premium, high-durability protection systems tailored specifically for South African property profiles.
Complete Overhead Protection
Every architectural substrate handles environmental expansion differently. Missing tiles, micro-fissures in concrete slabs, or failing overlaps on steel structures will quickly pull water directly into your interior assets. We don’t apply generic fixes—we match the engineered system to your exact structural framework.
1. Flat Concrete Roofs
Flat surfaces are highly susceptible to major water pooling. We deploy specialized, multi-layered 4mm heat-fused torch-on bitumen membranes that eliminate standing seam exposure. Every seam is fused thermally to ensure continuous water defense.
- Heat-Fused Membranes
- UV-Reflective Silver Topcoats
- Parapet Wall Tanking
2. Corrugated & IBR Metal Roofs
Metal surfaces experience severe temperature shifts, causing roof screw rubber washers to crack and lap joints to pull apart. We treat metal profiles with highly flexible fluid-applied acrylic or polyurethane membranes embedded with tough geo-fabric reinforcement.
- Lap Joint Sealing
- Screw Head Encapsulation
- Rust-Inhibitive Priming
3. Tiled Roofing Systems
When wind-driven rain forces water up underneath concrete roof tiles, failed sub-layer underlayments lead to direct ceiling failure. We replace damaged insulation blankets, seal valley linings, and coat worn, porous tiles with advanced waterproofing protectants.
- Under-Tile Membrane Replacement
- Valley Lining Upgrades
- Ridge Cap Cement Pointing
4. Exposed Balconies & Terraces
Balcony floors act as structural ceilings for the rooms beneath them. Standard tile grout absorbs moisture easily. We execute deep under-tile waterproofing tanking before screeding, or apply durable, UV-stable exposed traffic wear coats to block lateral water migration safely.
- Under-Tile Structural Tanking
- Expansion Joint Sealing
- Pedestrian Traffic Polyurethane Wear Coats
The Prop Seal Process
Substrate Decontamination
We strip failed waterproofing layers, wash down dirt or organic build-up, and repair the concrete, tile, or metal surface.
System Priming
A specialized substrate binder or bituminous primer is applied to anchor the upcoming structural waterproofing layers permanently.
Membrane Application
We apply our engineered heat-fused membranes or multi-coat elastomeric fluid systems with careful detail around water drains and flashings.
