Application

Can be used as:

  • A detailing product for Newton 403 HydroBond.
  • As a swelling adhesive for the installation of Newton System 300 hydrophilic waterbars.
  • Sealing of service protrusions through the structure.

To be applied with a standard mastic gun.

Description

Newton 306 LeakSeal is a high-quality, firm, fast-curing, swellable, single-component, polymeric adhesive sealant. The special composition makes the sealant start to swell when in contact with water (to about 200% of original size).

The sealant has high elasticity and high adherence, and it develops a strong adhesive tensile strength immediately after application. The first swelling is time delayed which allows Newton 306 LeakSeal to be applied to slightly damp surfaces.

The product is suitable for bonding Newton System 300 hydrophilic waterbars to concrete, plastics and steel as well as being a sealant for service protrusions through the structure.

Consult manufacturer's literature for relevant surface preparation.

Features and benefits:

  • Very high resistance to water pressure.
  • Delayed swelling - will not swell during the installation process or during the concrete cure.
  • Swells up to 200% its original size to quickly seal leaks at joints in the structure.
  • Resistant to the high alkalinity of concrete.
  • Maintains very high elasticity and tensile strength, even when swollen.
  • Age resistant, no embrittlement.
  • Suitable substrates include concrete, steel, plastics and rubber.
  • Has a service life that can be equal to the design life of the structure.
