InsuFort
Produced through a high-tech calendering process, Insufort features a non-woven polyester carrier saturated and coated with APP polymer-modified bitumen.
Engineered for the job it protects.
Produced through a high-tech calendering process, Insufort features a non-woven polyester carrier saturated and coated with APP polymer-modified bitumen. It delivers a longitudinal tensile strength of 800 N/5cm with 40% elongation at break, providing a robust waterproofing layer capable of withstanding high mechanical stress and substrate movement. Cold temperature flexibility down to -8°C and flow resistance up to 120°C make Insufort a reliable mid-to-high performance solution for a wide range of climatic conditions. It is suitable for flat and sloped roofs, foundations, basements, tunnels, wet areas, and slab-on-grade applications.
Insufort is applied using the torch-on method, creating a continuous and durable bond with concrete, metal, and other prepared surfaces. The APP modification ensures strong resistance to UV radiation, ageing, and thermal degradation, making it particularly effective in environments with intense sun exposure. Available with surface finishes including colored slates, aluminum foil, sand, and polyethylene film, Insufort is a dependable mid-to-high-grade APP membrane for projects requiring proven mechanical strength and lasting waterproofing integrity.
- APP modified bitumen with 800 N/5cm tensile strength for robust structural performance
- Durable polyester reinforcement for long service life under mechanical stress
- Strong UV, ageing, and heat resistance with flow resistance up to 120°C
- Suitable for roofing, foundations, basements, tunnels, and wet areas
- Torch-on application for secure, continuous waterproofing adhesion
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.
