During the home improvement process, especially waterproofing works are especially important in hidden projects. Some self-contained companies subcontracted waterproofing projects at a low price. These waterproofing companies used non-GB price waterproof materials with a price of RMB 80 per barrel. In addition, they used waterproof materials instead of waterproof materials. Is this material waterproof?

Again, the waterproof layer should extend from the ground to the wall, 100mm above the floor; the waterproof layer of the bathroom wall should not be less than 1800mm. The waterproofing project should be conducted two water storage tests, at least 24 hours in summer and at least 48 hours in winter. Consumers must pay attention to on-site acceptance.
