Redundant concrete waterproofing agent is a kind of high performance concrete waterproofing agent, after joining concrete, add water, after mixing with gelled material series reaction, activate the inert ingredient in concrete, refining the wool stoma, crystal form tendrils shape, with functions of crack healing, which to a certain extent, the subsidence caused by the crack of concrete can be adapted to foundation or other causes of cracking caused by leakage, called active concrete, its biggest characteristic is: even if the concrete cracking it wouldn't happen leakage, thereby significantly increased the probability of concrete leakage occurred.
