GEL Crystalline


Permanent Waterproofing for Concrete and Mortar by Crystallization


Permanent Waterproofing for Concrete and Mortar by Crystallization


  • Easy to use by mix with water
  • Excellent adhesion to substrates
  • The crystallization reaction between GEL CRYSTALLINE with free lime and calcium hydroxide in cement will form the crystal to fully block the capillary in the concrete and mortar. It gives permanent moisture and water proof.
  • Non-Corrosive and Non-Toxic
  • Can be use both positive and negative side of waterproofing


  • Used as waterproofing material in concrete such as reservoirs, dams, canals, concrete pipes, water treatment plants, Sea barrier, deck, bridge, etc.

Surface Preparation

  • Clean surface from dust, concrete debris or oil stain
  • Curing concrete with water until the surface is saturated
  • Remove the excess water (the surface must be damp but not wet)

Work Procedure

  • Mix GEL CRYSTALLINE 1 bag (25 kg.) with clean water approximately 7-8 L. (For vertical water should be reduce to prevent sagging.)
  • Mix with low speed (60 rpm) mechanical mixer at lease 3 min. until homogenous
  • Can be apply by brush, roller or trowel
  • Recommendation for 2 coat apply
  • Apply second layer by applying perpendicular to the first layer (The second coat should be apply when the first coat is dry enough, normally approximately 3-4
  • For new concrete: GEL CRYSTALLINE can be applying immediately after the formwork has been removing
  • For exist concrete: If there are static crack more than 1 mm. widths, should be repair before apply GEL CRYSTALLINE


  • Clean the tools immediately after use
