ArmTec HyperFlex over torch-on

Torch-on bitumen membranes were the default flat-roof waterproofing for decades, and thousands of Bloemfontein slabs wear one. They age predictably: the UV-protective mineral chips shed, the bitumen oxidises and goes brittle, joints open, and blisters form where trapped moisture expands in the afternoon heat.

The traditional fix — strip the old membrane and torch on a new one — is expensive, slow, and leaves your roof exposed mid-project. In most cases it is also unnecessary.

BloemGuard renews torch-on roofs by overlaying a reinforced liquid system directly over the prepared existing membrane. The old torch-on stays down as a base layer; the new system bonds to it, bridges its joints and cracks with mesh reinforcement, and finishes with a UV-stable topcoat that protects it from the sun that killed the original.

• ArmTec HyperFlex overlay — UltraBond WP primer over the entire surface (mandatory on torch-on), ArmTec mesh reinforcement over the full surface and at every joint, flexible membrane coats and UV-stable topcoat.
• UltraBond WP — the mandatory primer over torch-on and bitumen. It prevents off-gassing delamination; no topcoat ever goes onto torch-on without it.

1. Inspect & quote — we map blisters, open joints, punctures and previous repairs across the whole membrane.
2. Prep & repair — blisters cut out and dried, joints re-sealed, surface cleaned and primed.
3. Seal & reinforce — full-surface reinforced overlay, detailed at edges, outlets and penetrations.
4. Topcoat & sign-off — UV-stable finish, walkthrough and documentation.
