The elastic two-component waterproofing mixture “Hydrostop” PRG-02 is designed for waterproofing and protecting building structures inside and outside buildings: concrete, brick and plastered surfaces exposed to moisture and water, both during periodic and constant wetting.

And also with hydrostatic pressure of a water column up to 20 m high; walls and floors of bathrooms, showers, pantries, basements and other wet rooms.

For foundations, terraces, balconies, flat roofs, parapets, pools, tanks, including for the storage of drinking water and other hydraulic structures.

It can be used in the “warm floor” system, and the mixture is also used to protect concrete and reinforced concrete structures from atmospheric precipitation and exposure to carbon dioxide.

Prevents the destruction of building structures, heat loss, water leakage, mold, fungi, etc.

Elastic waterproofing PRG-02 is not the final coating and requires mandatory protection with other materials (tiles, polymer-cement plaster, paint, polystyrene foam boards).

It is applied by water.


The waterproofing mixture PRG-02 is not intended to localize the flow of oil products, diesel fuel, gasoline, kerosene, liquefied gases, lubricants, fuel oil, paraffin, tar and the like.
