Pentens T308 Flex | Flexible Crystalline Cementitious Waterproofing Compound

PENTENS T-308 FLEX is a two-component, penetrating cementitious, reactive crystalline nano-capsule core self-healing technology waterproofing material. 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. At micro level, shrinkage cracks from drying might create passageways for moisture infiltration. If problem occurs while crystals are still forming, micro-cracks up to 0.4mm can be bridged. If problems occur later, the water will infiltrate water reactive proofing chemicals, allowing the concrete to heal itself on a micro scale.

PENTENS T-308 FLEX technology enhances the natural hydration process in concrete, increases compressive strength over time and dramatically reduces cracks caused by shrinkage. PENTENS T-308 FLEX has the characteristic of apply self-sealing in 24 hours. PENTENS T-308 FLEX can be applied as a second coating to reinforce PENTENS T-308M Crystalline Cementitious Waterproofing Compound. For damp proof areas, T-308 FLEX can be applied to the concrete surface.
