Overview
Applied as a slurry or added as an admixture, crystalline waterproofing turns the concrete itself into the water barrier and resists negative-side pressure. Crystals can keep growing when water returns, sealing fine cracks up to the width the maker states.
It suits basements, tanks and buried structures where the outer face is hard to reach. It does not replace proper treatment of movement joints, construction joints or large structural cracks.
Uses
- 01Basement walls and slabs
- 02Water tanks and wastewater tanks
- 03Tunnels, buried structures and pits
- 04Concrete under negative water pressure
Selection and acceptance checks
- Confirm the crack width the product can seal per the maker
- Treat construction and movement joints separately with waterstops
- Moist-cure for the specified time
