SikaBit Pro Bituminous Membranes

These membranes offer the best of both worlds technologies, combining the flexibility and tensile strength of a Styrene Butadiene-Styrene (SBS) modified bitumen membrane with the hardwearing properties and UV stability of Amorphous Poly-Alpha-Olefins (APAO). This therefore means they ensure exceptional waterproofing protection for your property, along with proven application ease.

They have been developed to offer a secure and safe secure solution for any environment. The SikaBit® Pro Bituminous Membranes range includes detailing materials for completely flame-free Safe2Torch-compliant roof installations.
