Sealing clay

Clay TJN

Sealing (open caisson) clays are environmentally friendly however absolutely reliable means of environmental protection. The clays do not content any undesirable foreign matters. The clay barrier is built upon a physical principle, it is self-curable and it profiles ground movements without limiting its proper function. Thanks to their checked properties these clays represent a very convenient material for solving problems which may occur in building the anti-flood dams, for protection of waters against environmental contamination caused by filtration from refuse and waste yards, from depots of crude oil substances and from pipe lines. They are also suitable for sealing of open caissons and wells against filtration of ground waters.
