Markchem Krystol Admix
KRYSTOL ADMIX (integral crystalline waterproofing admixture) is added to the concrete mix at the time of batching. It consists of Portland cement, very fine treated silica sand and various active, proprietary chemicals. These active chemicals react with the moisture in fresh concrete with the by-products of cement hydration to cause a catalytic reaction, which generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete. Thus the concrete becomes permanently sealed against the penetration of water or liquids from any direction. The concrete is also protected from deterioration due to harsh environmental conditions.
KRYSTOL ADMIX has been specially formulated to meet varying project and temperature conditions
- Resists extreme hydrostatic pressure from either positive or negative surface of the concrete slab
- Becomes an integral part of the concrete
- Highly resistant to aggressive chemicals
- Can seal hairline cracks up to 1/64” (0.4 mm)
- Allows concrete to breathe
- Less expensive than traditional methods
- Added to the concrete at time of batching and therefore is not subject to climatic restraints
- Reduces construction scheduling time
- Improves durability of concrete
- Permeability Reducing Admixture for Hydrostatic conditions
- Zero volatile organic compounds and are safe for use both outdoors and in confined indoor spaces.
- Exceeds requirements of ASTM C494-S
- Non-toxic (NSF 61 certified for potable water applications)
- Reservoirs
- Sewage and Water Treatment Plants
- Secondary Containment Structures
- Tunnels and Subway Systems
- Underground Vaults
- Foundations
- Parking Structures
- Swimming Pools
- Pre-Cast, Cast-in-Place and Shotcrete applications
