Crystalline waterproofing is a technology that involves the development of crystals to help achieve watertight concrete structures. Seed Pvt Ltd crystalline waterproofing technology is available as a waterproof coating for concrete, or an integral admixture for concrete, for use in both above and below grade applications.

When crystalline waterproofing is applied to the concrete surface, either as a coating or as a dry-shake application to a fresh concrete slab, a process called diffusion takes place. The theory behind diffusion is that a solution of high concentration will migrate through a solution of lower concentration until the two equalize.
