The basement roof generally can not take place the condition of infiltration or leaking, but some local summer easily takes place heavy rainfall, for example south summer often has thunderstorm, falls a large amount of rainwater in short time, because of the rainwater is more, if the drainage is not smooth can take place ponding, the basement roof just can take place infiltration or leak very much this moment. The water permeating the top concrete layer 4 enters the water absorption groove 33, and then the water in the water absorption groove 33 is absorbed by the water absorption wool 322, so that the water is not easily accumulated on the waterproof roll 31, thereby allowing the water to permeate the waterproof roll 31 and the bottom concrete layer 1.
