HF Bentonite Waterproofing Membrane

HF Bentonite Membrane Type A (BS8102:2009) Waterproofing Membrane, BBA Accredited (Certificate 16/5330) polymer-modified, sodium bentonite geosynthetic clay liner with an LDPE laminated barrier designed to be applied in regular & extreme UK weather conditions, fast & simple application.

HF Bentonite Membrane excels as a leading product in the world of bentonite Geosynthetic Clay Liners. HF Bentonite Membrane, may be used wherever standard bentonite liners have been specified but as it is created using highly polymerised bentonite granules it also provides waterproofing security for constructions on contaminated land and in low-level saline groundwater conditions (always seek confirmation advice for specific site conditions).

5000g of polymer enhanced high swelling sodium bentonite granules per metre² are encapsulated, due to intense needle-punching, between extremely durable & strong polypropylene woven / non-woven geotextiles.

When applied under a concrete slab or within the concrete formwork an intimate mechanical bond is formed between the membrane & the concrete, minimising any possible water tracking. This application process removes the requirement for any weather-dependent primers & protection boards. Vertically, the BentoShield MAX LM membrane may be post applied using soft washer machinal fixings.

HF Bentonite Membrane has a 400-micron virgin polyethylene laminated sheet adhered. This sheet can be sealed using butyl tape to form a comprehensive basic radon barrier. All UK soils emit the hazardous ground gas Radon.

For added security, adjacent membrane laps can be sealed using a Bentopaste fillet or by applying butyl tape along with the polyethylene laminate films.
