Mapeproof HW

Eco-friendly bentonite waterproofing sheets for below ground level structures.
Mapeproof HW is certified as a “clay geometric barrier” by the BBA and is used for waterproofing and damp-proofing underground concrete structures. Mapeproof HW absorbs water and swells to form a waterproofing barrier. The swelling action can self seal around any fixings, encapsulating minor damage.
