Naturally occurring sodium bentonite granules ideal for detailing to the Newton HydroBond System where HydroBond 403 Plus terminates to building elements such as piled walls, support piles, pile caps, and protrusions through the membrane.
Bentonite is an absorbent clay formed millions of years ago from volcanic ash. There are different types of bentonite but all expand to an extent when hydrated. The sodium bentonite in HydroBond 314 Bentonite Granules can absorb many times its mass in water.
The property of swelling on contact with water makes sodium bentonite useful as a sealant since it provides a self-sealing, low permeability barrier. When in contact with water, HydroBond 314 Bentonite Granules swells up to 15 times its initial size to form a dense, water impermeable paste. When confined, the swell is controlled, forming a dense waterproofing component that fully seals these otherwise difficult to detail joints against water ingress.
