The slow-setting type is mainly used for moisture-proof and permeability-reducing purpose, and the quick-setting type is mainly used for impervious and leak stopping purpose.

I. Features of the product
1. Rapid water-seal and leak-stopping and the works can be executed without water cut.
2. Moisture-proof, permeability-reducing and permanent water-proof.
3. Firmly bonded with new and old buildings of concrete construction and masonry construction.
4. Works can be executed on the water face and the downstream face as well.

IV. Job practice

1. Leak stopping construction: Cut an opening with a certain depth (over about 5cm), with a large inside and small outside as far as possible, in the leaking point or leaking crack with a chisel or percussion drilling. The opening shall be as small as possible, but new concrete must be exposed and be cleaned up.
ProportioningThe leak stopping powder of quick-setting type must be selected for stopping leakage through the water leak slot (Hot water of 50-70℃ can be used to blend the powder to shorten the setting time). Repeatedly mould the leak stopping compound with powder-to-water proportion at 1:0.25 i
