IKO Tankstar T, when used on underground structures, provides a continuous waterproofing lining or ïtankingÍ to walls, floors and foundations, constructed in direct contact with the earth. In addition mastic asphalt can also be successfully used as part of a gas protection system.

The formulation of IKO Tankstar T includes the addition of Trinidad Lake asphalt. This gives the product improved laying qualities and greater thermal stability. When fully confined, IKO Tankstar T (High Performance Tanking) will provide an effective, seamless barrier to the transmission of water from the ground.
