Flat Roofs & Concrete Slabs

Double-touch torch-on bitumen for long-life sealing on slabs and flat decks.

Flat surfaces ponder water and need a fully bonded, multi-layer system. We apply double-touch torch-on bitumen membrane over a properly primed slab for an industrial-grade seal that handles foot traffic and ponding — proven across hundreds of Cape Town buildings.

— FAQs

Answers from our team.

Common questions about flat roofs & concrete slabs in Cape Town.

Can torch-on be installed over existing membrane?

Sometimes, if the existing system is sound. More often we strip back to the slab for a proper 20-year job.

Is there a fire risk?

Torch-on uses controlled flame in trained hands. We carry full public liability and fire-safety equipment on every job.

How long does it take?

A typical 100m² slab takes 2–3 days including prep, primer cure and the two membrane layers.
