La description
HongyuanTM cement-based capillary crystalline waterproofing coating
(CCCW), which is in the form of gray powder, is composed of
ordinary Portland cement as base material and active chemicals.
Carried by water, the active chemicals penetrate into concrete
substrate and react with unhydrated cement granules to produce
insoluble crystals, which block the capillary channels in concrete,
making the concrete itself become waterproof. When small cracks
develop in the concrete substrate due to internal stress or
external force, as along as there is water, the above mentioned
reaction will happen again and the crystals produced will fill the
cracks, realizing self-repair.
This product is applicable to the waterproofing of tunnels, dams,
reservoirs, power stations, nuclear power plants, cooling towers,
underground railways, overpasses, bridges, underground diaphragm
walls, airport runways, pile head and pile foundation, purification
tanks for liquid waste, basements, roofs, bathrooms, etc., as well
as to the leak repairing and stopping of concrete structures.Â
