Waterproof membranes are used in basements, foundations, podium decks, roofs, and retaining walls to stop water ingress. They can be:
- Sheet membranes (pre-formed rolls)
- Liquid-applied systems
- Cementitious waterproof coatings
- Fully bonded or cavity drainage systems
The correct membrane depends on hydrostatic pressure, ground conditions, and the structure’s use.
In below-ground applications, membranes are often installed as part of a wider waterproofing strategy to manage groundwater and prevent dampness.
Why It Matters
Uncontrolled water ingress can lead to:
- Reinforcement corrosion
- Concrete deterioration
- Internal damp issues
- Structural damage
Proper membrane specification and installation are essential to ensure long-term durability and compliance with UK waterproofing standards.
