Field of Application

 Producing impermeable concretes to water and chemical solutions,
Producing resistant and durable concretes for low temperatures and freezing conditions,
Sealing the concrete in hydraulic structures,
Producing durable concretes for concreting the water resources and reservoirs, retaining walls, water channels, tunnels, bridges, dams, pools, basins and other concrete surfaces,
Suitable for sealing and providing impermeable masonry mortar and grouting.

Properties and Effects

 Reducing permeability and percolation of concrete to water and corrosive chemical solutions,
Increasing the integrity and uniformity of concrete,
Reducing the effects of concrete bleeding and cracking,
Increasing the concrete durability and protecting the bars,
Reducing the carbonation rate.


Depending on the conditions and consumption cases, use BC39 Up to 2% of cement weight. Approximately 3.5 to 7 kilograms of BC39 per square meter is needed

Instruction for use

After concrete components were thoroughly mixed, add BC39 to the mixture and continue mixing for 2 minutes

Technical observation and application

 The overuse of the product delays the concrete setting
In high hydrostatic pressure conditions, use BC39 with super plasticizer and water
reducing additives. In certain cases, use BC18, BC19 or BC17
An equivalent part of consumed liquid waterproof should be reduced from the ratio of
water to cement
When simultaneous use of BC39 with other additives is required, consult Research Center
of Beton Chimie
