Admixtures are usually stored in bulk, in plastic tanks, metal tanks or barrels. Modern bulk plastic storage tanks are double-skinned to minimise the risk of leakage from a skin splitting. If doubled-skinned tanks are not used, the admixture storage area should be bunded to prevent spillage entering the water system.
Admixtures should be protected from freezing. All tanks and pipes should be clearly marked with their contents and the shelf life of the product should be indicated.
If an admixture exceeds its storage life or is no longer required, it must be disposed of through an approved contractor.
