Description

A combined water resisting and crystalline waterproofing admixture used to reduce permeability of concrete and has the ability to heal cracks. Consists of a mixture of cements, amino alcohols and fillers. These active materials will form non-soluble materials throughout the pore and capillary structure of the concrete and seal the concrete permanently against penetration of water and other liquids. In addition the special formula and ingredients enhances the self-healing properties of concrete.

Benefits:

  • Reduced water penetration under pressure.
  • Reduced water absorption.
  • Enhancement of self-healing properties of the concrete.
  • Improvement in resistance against chemical attack.
  • Reduced vapour transmission.

Uses:

Specifically formulated to produce high quality waterproof concrete. Treated concrete is used as a part of the Sika® Watertight Concrete System.

Can be used in any below, in or above ground watertight structures such as:

  • Basements.
  • Parking garages.
  • Utility or plant rooms.
  • Tunnels.
  • Swimming pools.
  • Water retaining structures.
  • Dams.
  • Waste water treatment structures.
