Water seepage on the wall around the balcony floor drain pipe

We can only negotiate with the property. This should be because the waterproof treatment upstairs is not good, which leads to water storage in the waterproof layer and the ground, and then slowly leaks to your home. This is because this is a new house. After finding the property, the property will contact the developer. When dealing with it, remember that the waterproof layer can't be re-laid immediately after the waterproof layer is dug upstairs. You have to wait until the ground upstairs is completely dry before repaving the waterproof layer. In addition, it is recommended not to use coiled materials for floor drains and wall pipes upstairs. Polyurethane will be better, but it will taste great. It is estimated that waterproof materials such as polypropylene will be used in property repair, but the requirements for construction quality are higher! !

The warranty period of the house is roughly as follows: the basic project and the main structure project are the reasonable service life of the project specified in the design documents; Roof waterproofing works, leakage prevention for bathrooms, rooms and external walls with waterproof requirements, 5 years; The heating and cooling system consists of two heating periods and cooling periods; Electrical piping, water supply and drainage piping and equipment installation for 2 years; The renovation project will last for 2 years.
