Dr. Fixit Krystaline Admix — Crystalline Waterproofing Admixture for Concrete (20 Ltr)

Concrete is never truly watertight on its own. Even a well-designed mix carries a network of capillaries, micro-voids and shrinkage cracks that water can find its way through — and once water gets into the matrix, it carries chlorides, sulphates and dissolved salts with it, attacking reinforcement and degrading the structure from the inside. Surface waterproofing membranes deal with this from the outside, but they're vulnerable to damage during backfill, screeding and follow-on trades. Crystalline waterproofing takes a different approach, and Dr. Fixit Krystaline Admix from Pidilite Industries Ltd. is the integral crystalline technology that contractors reach for when the waterproofing has to live inside the concrete itself.

Krystaline Admix is dosed into the concrete during batching. Once the concrete cures and comes into contact with moisture, the active chemicals in the admixture react with free lime and water in the matrix to form insoluble crystalline structures that grow into the capillaries and micro-cracks — physically blocking the pathways water would otherwise travel through. The behaviour that makes the technology distinctive is that it stays reactive over the service life of the structure. If a hairline crack opens up years after casting and water enters it, the unreacted crystalline chemistry in the matrix activates again and seals the new pathway. The waterproofing is self-healing in a way that membranes and coatings simply cannot match.

This is why it has earned its place in the most demanding waterproofing applications — basement raft slabs and retaining walls, underground water tanks, sewage and effluent treatment structures, swimming pools, tunnel linings and lift pits. These are projects where access to redo waterproofing later is either prohibitively expensive or physically impossible, and where the waterproofing system has to last as long as the concrete it's protecting. Engineers and waterproofing consultants specify Krystaline Admix on these structures because it converts the concrete itself into the waterproofing barrier, rather than relying on a separate layer that can fail independently.

A construction chemical from Pidilite Industries Ltd. that solves waterproofing at the structural level — Dr. Fixit Krystaline Admix is the crystalline admixture specification for water-retaining and water-excluding structures where surface systems aren't enough.
