Newton HydroBond 314 Bentonite Granules 20kg
Newton HydroBond 314 Bentonite Granuela is a naturally occurring sodium bentonite in the form of varying sizes granules, used for detailing to the Newton HydroBond System, specifically where Newton HydroBond 403 terminates to otherwise difficult to detail building elements, such as the base of 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 Newton HydroBond 314 Bentonite Granuela 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 Granuela swells up to 20 times its initial size to form a dense, water impermeable paste. When confined, the swell is controlled, forming a pressurised, dense waterproofing component that fully seals these otherwise difficult to detail joints against water ingress.
TYPICAL APPLICATIONS
Newton HydroBond 314 Bentonite Granuela can be mixed with clean water to seal elements of Type A and Type B waterproofing systems:
- Sealing of pipes, sleeves, columns and posts that penetrate the Newton HydroBond System
- Between the horizontal and vertical application of Newton HydroBond 403 to irregularly shaped interfaces such as piled walls
- Can be poured into an inverted fillet formed within the blinding as a termination detail where horizontal HydroBond 403 terminates at elements that are not to be further waterproofed
