InsuMeric
Manufactured through a high-tech calendering process, Insumeric is produced by saturating and coating a polyester carrier with SBS elastomer-modified bitumen compound.
Engineered for the job it protects.
Manufactured through a high-tech calendering process, Insumeric is produced by saturating and coating a polyester carrier with SBS elastomer-modified bitumen compound. Available in both fiberglass and polyester reinforcement variants, it provides absolute impermeability to water, superior chemical resistance to alkaline and light acidic solutions, and solid thermal stability under varying temperature conditions. With cold temperature flexibility down to -8°C, Insumeric performs reliably in a range of climatic conditions and is suited for flat and sloped roofs, foundations, basements, tunnels, wet areas, swimming pools, and slab-on-grade applications.
Insumeric is applied using the torch-on method, adhering securely to concrete, metal, and other prepared surfaces to form a seamless waterproofing layer. Its elastomeric SBS compound allows it to accommodate structural movement without cracking, providing consistent protection even under dynamic load conditions. Available with surface finishes including colored slates, aluminum foil, sand, and polyethylene film, Insumeric is an accessible and dependable SBS membrane for projects where flexibility, chemical resistance, and ease of installation are key considerations.
- SBS elastomeric modified bitumen for reliable flexibility and chemical resistance
- Available in both polyester and fiberglass reinforcement variants
- Cold temperature flexibility down to -8°C for performance in variable climates
- Suitable for roofing, foundations, tunnels, wet areas, and swimming pools
- Torch-on application for easy installation and secure 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.
