HYDROZOL® НВМ PRO (SBS-PE) - Hydro insulation membrane from SBS modified bitumen reinforced with polyester

Hydro insulation membrane from SBS-Premium modified bitumen reinforced with polyester, with high elasticity, flexibility and tensile strength in wide operating temperature range: from -25°C to +100°C


- excellent elasticity in both low and high temperatures (-25°C to +100°C);

- for applying on hardly reachable areas with complicated construction;

- SBS-Premium modification of the bitumen;

- basic hydro insulation layer in a multilayer bituminous waterproofing of flat and other roofs;

- suitable for subterranean and dynamically loaded hydro insulations;

- high resistance to aging.





Scope of use

HYDROZOL® HBM PRO (SBS-PE) is highly flexible hydro insulation membrane which provides secure and long lasting protection from water penetration. The product is made up by elastomeric polymers (SBS) high-quality bitumen content, which is layered on both sides with polyester. The SBS-Premium high modification of bitumen with elastomeric polymers provides excellent low-temperature flexibility. It also guarantees long-term durability (25 years) and resistance to aging at extreme operating temperature range (from -25°C to +100°C) without being influenced by frequent and abrupt change in ambient temperature.

The polyester reinforcement increase the membrane`s strength and makes it highly flexible and elastic. The product is perfect for applying on hardly reachable areas with complicated construction, multiple angles. In such places where high flexibility of the membrane is needed in order for it to be placed properly. Although the membrane has high elongation properties, it does not tear or puncture easily. If the temperature of the surrounding is changing, the membrane still has its water impermeability.

The membrane is used as first hydro insulation layer in a multilayered hydro insulation (over bituminous membrane without slate) of flat and inclined roofs. It is suitable for subterranean and dynamically loaded hydro insulations (canals, tunnels, parking areas, bridges and others).

The membranes are both sides covered by polyethylene film which preserves the adhesive properties of the rolls during the storage. The application of the membrane (using torch) is extremely strong thus adhesives are not necessary.

HYDROZOL® HBM PRO (SBS-PE) is a component of the multilayer system of bituminous hydro insulation. It cannot be used as finishing layer. It should be protected by HYDROZOL® HBM (SBS-PEP), hydro insulation membrane with SBS-Premium bitumen and fiberglass reinforcement covered by slates.

If used properly, the product has minimum 25 years of service life.
