Understanding Type A, B & C Waterproofing Systems
Type A – Barrier Waterproofing Systems
Type A systems prevent water ingress by forming a physical barrier on the internal or external face of a structure. These systems are commonly specified where water must be blocked at source.
- External tanking membranes
- Internal cementitious waterproofing
- Liquid-applied waterproof coatings
- Gas and moisture barrier membranes
Type B – Integral Structural Waterproofing
Type B systems provide waterproofing within the concrete structure itself, forming part of the building’s construction. These systems are typically specified for new builds and reinforced concrete structures.
- Integral concrete admixtures
- Construction joint sealing systems
- Waterbars and joint protection products
Type C – Drained Waterproofing Systems
Type C systems manage water ingress by controlling and safely draining it, rather than blocking it. This approach is widely used for basements, conversions, and refurbishment projects.
- Cavity drain membranes for walls and floors
- Perimeter drainage channels
- Sump chambers, pumps, and battery backup systems

Quick FAQs
What do Type A, B and C mean in BS 8102?
BS 8102 categorises waterproofing into Type A (barrier protection), Type B (structurally integral protection), and Type C (drained protection). Systems can be used individually or combined depending on site risk.
Which waterproofing system is best for basements?
Type C cavity drain systems are commonly used for basement conversions and refurbishments, while Type A and Type B systems are often specified for new builds. Higher-risk sites may require combined protection.
Can Type A, B and C systems be combined?
Yes. Combined waterproofing designs are frequently specified to provide additional protection, particularly in areas with high groundwater levels.
Do you offer next-day delivery?
Yes. Next Day UK delivery is available on most stocked waterproofing products.
