From the cation exchange capacity of bentonite waterproof blanket resolution quality, absorbing the higher the amount of blue and cation exchange capacity, decentralized expansion possible. Some experts believe that as long as the swelling index and filtration qualified, not necessarily required amount of blue smoke natural waterproof blanket manufacturers, because a lot of good bentonite gel its blue smoke amounted to less than industry standards. Bentonite content subject to tests to determine the actual situation. Second, the basic requirements: 1, basis of soil compaction (density of ≥85%) GCL mat, to avoid damage during use because the underlying cause of the sinking of the permanent use of adverse factors. 2, foundation soil formation and must not have sharp objects such as stones, to avoid being punctured affecting GCL waterproof effect. As mainly the flatness 3500g waterproof blanket, suggested 300mm thick sand or 30mm --- 50mm thick layer of cement mortar. 3, GCL in a wet environment construction, but should avoid soaking in water. 4. The foundation soil below the bottom of the water table elevation, rainfall should take effective measures to drain the water. 6mm waterproof blanket _ Edison new materials shares (certified) _ GCL new material provided by the Edison Company.
