Waterproofing That Lives Inside the Concrete
Engineered by ConChem Labs®, CrystaFlex™ is a high-performance integral crystalline waterproofing admixture designed to enhance the durability, impermeability, and long-term structural integrity of concrete.
Unlike surface-applied systems, CrystaFlex™ becomes a permanent part of the concrete matrix — protecting from within and delivering measurable performance against water ingress, chlorides, sulphates, and hydrostatic pressure.
Designed for performance-driven construction, it integrates seamlessly into standard concrete practices without altering conventional mix procedures.
Why CrystaFlexTM?
Surface membranes can deteriorate. External coatings can fail. CrystaFlex™ works internally — where durability truly matters.
By activating a crystalline reaction within the concrete matrix, it transforms ordinary concrete into a dense, water-resistant structural element capable of long-term protection in aggressive environments.
It is not a coating. It is structural waterproofing.
Active Crystalline Technology
Active Crystalline Technology improves concrete durability by blocking pores, reducing water penetration, and enabling self-sealing of microcracks.
Forms additional C-S-H gel structures within the concrete matrix.
Generates insoluble crystalline formations that block pores and capillaries.
Reduces permeability and restricts water migration.
Enhances resistance to chloride and sulphate attack.
Improves performance under hydrostatic pressure.
Supports autogenous crack-sealing of microcracks up to 0.3–0.5 mm over time.
Performance Benefits
Significant reduction in concrete permeability
Integral, non-leachable waterproofing system
Improved resistance to aggressive chemicals
Enhanced durability in wet and high-humidity conditions
Increased service life of reinforced concrete structures
Reduced lifecycle maintenance costs
Potential elimination of external waterproofing layers.

Method of Use
Remove Sachets
- Remove the required number of sachets as per recommended dosage.
Add Sachets
- Add the unopened water-soluble sachet directly into the concrete mixer.
Mixing Sachets
- Allow standard mixing time to ensure uniform dispersion.
Seal Sachets
- Do not cut or open the sachet. it dissolves completely during mixing.
