Deep Penetration Crystal Sealer

Deep Penetration Crystal Sealer 

DPS, is the abbreviation for Deep Penetration Sealer (deep penetration crystalline waterproof material). Is the domestic national standard definition, is water-based (or water, water-based) infiltration crystalline inorganic waterproof material.

Waterproof mechanism

Its water-proof mechanism is a chemical reaction with the free base in the concrete to produce a stable dendritic crystalline colloid, which can effectively block the fine cracks and capillary voids inside the concrete, so that the concrete structure has a lasting waterproof function and better density And compressive strength. Penetration depth of 20-30mm, but also can effectively prevent the acidic substances, oil and oil erosion of concrete. Can be used in any case of concrete base.


One does not need to find leveling and protective layer, directly in the concrete layer can be sprayed 2 times, each worker can build 1000 square feet / day;

Two infiltration grade to S11 or more;

Three shelf life of more than 50 years. Not aging, deterioration;

Four can be wet construction surface construction, conservation period is very short, not afraid of rain;

Five after pouring the floor to do waterproof construction, can save a long time period;

Six completely environmentally friendly non-toxic, do pool pool and other internal walls;

Seven prices are lower than other materials.
