5kg/m2 Needle-Punched Sodium Bentonite Waterproofing Membrane - BM-01

Description

YHSY Bentonite membrane is a highly effective waterproofing composite, of high strength green coloured geotextile, and sodium bentonite. The high swelling sodium bentonite is encapsulated between a non - woven and woven geotextile. A ‘needle-punch’ process, interlocks the geotextiles together forming an extremely strong composite that maintains the equal coverage of bentonite, as well as, protecting it from inclement weather and construction related damage.

When wetted, unconfined bentonite can swell up to 20 ~25 times its dry volume. When confined under pressure the swell is controlled, forming a dense, monolithic, impervious waterproofing membrane.

The swelling action of YHSY Bentonite membrane can selfseal small concrete cracks caused by ground settlement, concrete shrinkage, etc.

YHSY Bentonite membrane forms a strong mechanical bond to concrete, when the geotextile fibres are encapsulated into the surface of insitu concrete.
