Small components that make a significant impact on your WaterProofing success

When it comes to keeping water out of your basement, foundation, or other below-ground structures, prevention is always better than repair. Our WaterProof swellables offer a simple, highly effective solution for sealing construction joints, pipe penetrations, and other critical areas prone to water ingress – helping you achieve BS 8102:2022 compliance with confidence.

Why Choose WaterProof Swellables?

Engineered to Swell on Contact with Water

Our swellable profiles expand to create a tight, durable seal that blocks water pathways before leaks can occur.

Ideal for Type B WaterProofing Systems

Perfectly suited for integration with reinforced concrete structures, enhancing the built-in WaterProofing design.

Compliant with BS 8102:2022

Supports the latest British Standard recommendations for protecting structures below ground from water from the ground.

Versatile & Reliable

Suitable for use in new builds, renovations, and complex detailing – from lift pits and retaining walls to service entries.

Long-Lasting Performance

Resistant to repeated wet/dry cycles and ground contaminants, ensuring consistent protection over the life of the structure.

Applications

• Construction joints in concrete walls and slabs

• Around pipe and service penetrations

• Precast element interfaces

• Pile caps, capping beams, and diaphragm walls

How They Work

When our swellable strips or rings and plugs come into contact with moisture, they expand larger than their original size. This swelling action fills gaps, irregularities, and voids in the joint, creating a watertight barrier that stops water at its source.

Achieve BS 8102:2022 Compliance

The latest BS 8102 standard emphasises integrated WaterProofing design and robust detailing to resist water ingress. By incorporating WaterProof Swellables into your Type B system, you:

• Reduce the risk of leaks through critical joints

• Provide redundancy in your WaterProofing strategy

• Meet compliance requirements with proven, tested technology

• Your Structure Deserves the Best Protection
