Cement-based composition, with predefined quartz sand grain sizes and special penetrating and crystallization accelerating additives. 

HIDROSTOP PENETRAT has two functions:
Capillary - active chemical admixtures penetrate deep into the pores of the construction material, form insoluble crystals, thus sealing the pores and protecting the material from penetration of water and other liquids. 

Barrier function - formation of a solid and waterproof insulation layer on the construction material surface.
Waterproof penetrant HIDROSTOP PENETRAT assures the most effective permanent sealing of concrete surfaces, thus preventing water penetration. It features the following advantages: in-depth action, ensured waterproofing despite surface damage, crystallization products seal the pores and capillaries in the concrete, 100 % water tightness, resistance to positive and negative water pressures, water vapour-permeability, application onto moist mineral substrate, simple use, frost-resistance. Permanent and effective waterproofing protection of concrete surfaces. For protection from moisture and water, sealing in showers, sanitary areas, bathrooms, swimming pools and laundries, for sealing inside cellar surfaces and water reservoirs etc.
