Used in the detailing of HydroBond Pre-Applied Membranes

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.

Key Benefits
  • Hydrophilic – swells to 15 times its initial size when contacted by water.

  • High resistance to water pressure.

  • Easily applied by hand.

  • Cost is much less than modern polymer type products.

  • Naturally occurring product.

  • Persistently elastic – no embrittlement.

  • Can be installed in almost any weather condition.

  • No VOCs.

  • Has a proven track record of effectiveness on both new and remedial waterproofing projects worldwide over many years.

Typical Applications
  • Can be mixed with clean fresh water to seal parts of Type A and B waterproofing systems where a reinforced concrete construction is used.
  • Sealing of pipes, sleeves, columns and posts that penetrate the Newton HydroBond System.
  • Between the horizontal and vertical application of HydroBond 403 Plus 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 Plus terminates at elements that are not to be further waterproofed.
  • Sealing cored holes within Type B construction in conjunction with suitable Newton repair mortars to confine the product.
Suitable Substrate and Materials
  • HydroBond 403 Plus
  • Plastic and ceramic/clay pipes.
  • Concrete.
  • Steel.
