TANKING

Mastic asphalt, when used on underground structures, provides a continuous waterproof lining or tanking to walls, floors and foundations, constructed in direct contact with the earth.  In addition mastic asphalt is used for lining structures in water and sewage treatment works.

When fully confined it will provide an effective barrier to the transmission of water from the ground for the design life of the structure in which it is incorporated.
