 The floor drain is the place where the ground drainage is concentrated, and it is easy to cause leakage, and the cast iron floor drain has a small bottom and is in contact with the concrete on the outer surface. Due to the shrinkage of the concrete, cracks are likely to occur, resulting in water seepage around the floor drain. The ground floor should generally be on the floor. Reserve holes, and then install the floor drain. After the floor drain is installed and fixed, detailed waterproofing should be done.

Filling the groove coating: the grooves around the upper opening of the floor drain should be tightly embedded with sealing materials, and then a waterproof additional layer of coating film with carcass reinforcement material should be laid.
