InsuSol
Manufactured with premium bitumen modified with Atactic Polypropylene (APP) and reinforced for strength and stability, Insusol provides excellent resistance to heat, ageing, and weather exposure.

Engineered for the job it protects.
Manufactured with premium bitumen modified with Atactic Polypropylene (APP) and reinforced for strength and stability, Insusol provides excellent resistance to heat, ageing, and weather exposure. Ideal for both above-ground and below-ground applications, Insusol is commonly used on flat and low-slope roofs, foundations, basements, podiums, terraces, and wet areas. Its enhanced thermal resistance makes it especially suitable for regions with high temperatures and strong UV exposure.
Insusol is easy to install using torch-on application, forming a seamless, durable waterproofing layer that adheres securely to concrete, metal, and other prepared substrates. Once installed, it delivers reliable protection against water ingress, moisture damage, and structural deterioration.
- APP modified bitumen for superior heat and UV resistance
- Strong, durable reinforcement for long service life
- Excellent waterproofing performance
- Suitable for roofing, foundations, and wet areas
- Torch-on application for secure adhesion and seamless coverage
The underside of the membrane is laminated with a thin, thermo-fusible polyethylene burn-off film to ensure efficient torch application and optimal adhesion. The membrane is available with a wide range of upper surface finishes, including multi-colored mineral slates, aluminum foil, sanded finishes, and polyethylene film.








Custom surface options and colors are available on request.

Application, Step by Step.
Clean the substrate of dust, debris and standing water, then repair any cracks or voids so the membrane can bond to a sound, even surface.
Apply a bituminous primer evenly across the whole surface and allow it to dry completely before any membrane work begins on the area.
Unroll and align the membrane on the primed surface, allowing the specified side and end overlaps before any bonding takes place.
Heat the burn-off film with a propane torch while progressively unrolling, pressing the membrane firmly onto the prepared substrate.
Torch and seal every overlap with a rounded trowel, checking each joint to achieve continuous, fully watertight seams across the surface.
Finish upstands, drains and penetrations with reinforcing details, then protect the membrane before backfilling, screeding or tiling.
