Flexobit: “The Original”

Flexobit waterproofing membrane

Flexobit is a 5 mm smooth, non-reinforced SBS waterproofing membrane that adapts seamlessly to any surface, reducing cutting and speeding up installation. Its SBS polymer-modified bitumen formula ensures superior adhesion, flexibility, and long-lasting protection.

Ideal for even demanding projects, Flexobit provides reliable waterproofing for foundations, basements, terraces, underground parking, expansion joints, elevator shafts, recesses, and concrete pile heads. Self-adapting and durable, Flexobit delivers peace of mind for every below-grade application.

What makes Flexobit “The Original”?

Flexobit is a pure, non-reinforced SBS-bitumen membrane, designed without any reinforcement carrier, creating a fully homogeneous compound with no polyester, glass, or fillers. Its exceptional elasticity and flexibility, with elongation up to 1,600%, allow it to adapt to structural movement far beyond conventional membranes.

The material naturally self-heals small punctures, while its reinforcement-free design ensures true 3D mouldability, bending, folding, and wrapping around complex details without compromise. Fully torch-welded overlaps deliver a single, seamless waterproofing layer—monolithic waterproofing as it was meant to be.

Flexobit is certified according to European standards, guaranteeing top-quality performance and reliability.
