It also prevents root penetration from the junction. In addition, a cushion body having a water passage hole communicating the upper and lower surfaces and a communication groove on at least the lower surface protects the resin sheet and the waterproof layer by absorbing the weight of the soil and external impact force, and furthermore, the filter material is used for the filter material. Excess water in the soil is guided to the lower cushion body, and this water is also discharged to the outside through the water holes and the communication grooves of the cushion body, so that drainage is improved. Further, when the resin sheet is made white, it is difficult to absorb solar heat at the time of construction, so that heat shrinkage of the sheet does not occur and construction is facilitated.

And a water-impervious sheet such as a resin sheet such as PVC. When asphalt roofing is used, an asphalt waterproofing layer obtained by laminating asphalt roofing using hot asphalt as an adhesive on a sheet obtained by attaching an adhesive layer of a rubberized asphalt sheet to the main body of the rubberized asphalt sheet on the base surface 2 Is desirable. This is because the asphalt waterproof layer can sufficiently follow the behavior of the ground surface, and can maintain waterproofness for a long time.
