Crystalline Admixture Waterproofing


PENTENS T-308 is a reactive crystalline type waterproofing material which is formulated by proprietary blends of chemicals (mainly organic and inorganic salts), quartz, sand and cement. PENTENS T-308 is an environmentally friendly and low VOC material. It is an integral waterproofing system that is being added to batches of concrete during mixing process. The active chemicals which react with moisture and free lime in the concrete or cement-based materials will cause a catalytic reaction that creates a non-soluble crystalline formation which crystallizes in the pores and capillary tracks. In the long run, under a supersaturation environment inside concrete, PENTENS T-308 initiates crystallization process. When this process takes place, millions of needle-like crystals are formed and fill the capillary tracks, pores and microscopic voids within the concrete. Paths for harmful moisture and aggressive chemicals are blocked permanently. PENTENS T-308 is added to batches of concrete during the mixing process for new construction projects. The high-growth organic component of the product reacts with water and unhydrated particles in concrete to form millions of needle-like crystals. These crystals grow and migrate through the concrete to fill in hair-thin pores and microscopic voids up to 0.4mm that would otherwise serve as passages for harmful moisture. 
PENTENS T-308 technology enhances the natural hydration process in concrete, increasing compressive strength over time and dramatically reducing cracks caused by shrinkage.

PENTENS T-308 is used to waterproof areas as indicated below:
  • Basement floors and retaining walls
  • Concrete flat roofs
  • Water retaining structures
  • Lift pits
  • Swimming pools

  • Low VOC.
  • Environmentally friendly.
  • Easy to use - only mix with concrete.
  • It provides significant cost saving because it eliminates labour cost in the long run.
  • Integral protection for the entire concrete.
  • Permanent protection even if the surface is damaged.
  • Can seal the capillaries and minor shrinkage cracks up to 0.4mm through crystal formation.
  • Protection from any direction.
  • Time-saving.
  • Non-toxic.
