WATERPROOFING THAT REACTS TO WATER.
When you're building below ground, keeping water out starts with choosing a waterproofing system designed for the conditions it will face.
Wykamol Bentonite Waterproofing uses the natural swelling properties of sodium bentonite to create a highly effective waterproof barrier around below-ground concrete structures.
WHY BENTONITE?
Encapsulated between woven and non-woven geotextiles, the bentonite membrane is designed to bond to fresh concrete and swell when it comes into contact with water.
That swelling action helps form a low-permeability barrier against water ingress.
And it doesn't stop there:
✅ High swelling capacity – expands up to 15× its dry volume
✅ Self-healing properties – helps seal small punctures or damage
✅ Fully bonds to fresh concrete
✅ BBA accredited and tested for BS 8102 compliance
✅ Suitable for below-ground waterproofing
✅ Can be installed in challenging site conditions
IDEAL FOR
🔹 Basements & foundations
🔹 Lift pits
🔹 Cut-and-cover tunnels
🔹 Swimming pools & water tanks
🔹 Spray-applied concrete structures
The system is also supported by ancillary products including bentonite granules, sealants and fixings for detailing and installation.
