Professional Waterproofing Protection with Sikalastic-685

Sikalastic-685 is a one-component, solvent-free bituminous membrane designed for comprehensive waterproofing of building structures exposed to water and moisture. This liquid membrane creates a continuous, durable protective barrier that prevents water penetration while accommodating structural movement.

Key Features & Benefits

Superior Crack Bridging

The flexible formulation bridges cracks up to 3.5 mm, providing reliable protection against structural settling and thermal expansion without loss of waterproofing integrity.

Exceptional Durability

Advanced resistance to UV radiation, thermal cycling, and weathering ensures the membrane maintains its protective properties for decades, even in severe exposure conditions.

Strong Adhesion

With adhesion strength of ≥2.5 MPa, the membrane bonds securely to substrates, preventing water infiltration at the critical interface between membrane and structure.

Ideal Applications
