A PE rod is placed on the lower layer or the module, and then a layer of module is placed thereon, and waterproof sealing glue is applied after the module is accurately positioned. A 5mm-thick polymer cement waterproof mortar is brushed on the outer wall at the gap between the upper and lower modules. In order to further prevent water seepage, a 1.5mm-thick silane modified polyether waterproof coating 15 is applied on the 100mm-wide upper and lower parts of the joint, and then the polymer cement waterproof mortar is brushed.
