SpECtite WS

SpECtite WS crystalline capillary waterproofing system contains proprietary blend of Portland cement, quartz aggregate and special chemicals. In the presence of moisture, the active chemicals in SpECtite WS crystalline waterproofing system penetrates concrete and react chemically with free lime to produce insoluble crystals. This crystalline growth reduces porosity by blocking capillaries and filling hairline non-structural cracks (up to 0.25mm wide) caused by shrinkage or expansion. Unlike metallic and membrane types of waterproofing which only form a surface barrier, SpECtite WS crystalline waterproofing system, in the presence of water, continues producing crystals and lasting imperviousness to water.

TYPICAL USES
SpECtite WS crystalline waterproofing system is used for waterproofing against the positive or negative sides of hydrostatic heads of water and damp proofing in a wide range of conditions like:

• Sewage treatment and water treatment plants, tanks, foundations, tunnels and manholes.
• Terrace garden, balconies, sunshades, etc.
• Roof and Sunken slabs.
• Industrial and Office buildings.
• Reservoirs, water holding structures, etc.
