The top of the coil should be higher than the maximum water level of about 500mm, the outer side of the brick wall.
Q:Why do the basics of the cushion waterproofing
Raft foundation do not do waterproof mainly depends on the design of the groundwater level considerations, calculated if the floor itself to meet the requirements, you can not do, and not rigid to do
Q:The cushion is usually in the housing which parts
