Blind Side Waterproofing

Blind side waterproofing with bituminous membranes is ideal for below-grade structures where exterior wall access is restricted, such as in urban environments or adjacent to existing buildings. In this method, bituminous membranes are pre-applied to a substrate like shotcrete or sheet piling before the concrete wall is poured. The membrane bonds directly with the concrete, creating a watertight barrier that resists water seepage and hydrostatic pressure.

Key benefits include strong adhesion to concrete, robust moisture protection, and durable performance. These membranes, reinforced for strength, form a continuous, puncture-resistant layer that ensures long-term structural integrity.
