Waterproof polymer mortar treatment scheme at the grass-roots level

Polymer waterproof mortar basic level processing plan 1. At the grass-roots level should be smooth, impervious, surface should be clean. When more grass-roots flatness deviation is allowed, appropriate USES appropriate material stuck between filling-in or flat. 2. The waterproof construction of polymer mortar, concrete goods masonry mortar compressive strength at the grass-roots level shall not be less than 80% of the design value. 3. Appropriate USES the base at the grass-roots level surface mortar ( Beauty or concrete interface treatment seam an agent for processing) ； When using the processing of polymer waterproof mortar, the interface, don't do processing. 4. When pipes, floor drain, etc. Through the floor, wall, should be a certain slope with pipes, floor drain the roots of the ring grooves, and embedded fill out the appropriate waterproof sealing material. In addition, the information of note: 1. Before construction, waterproof polymer mortar related equipment fix embedded parts and pipes should be installed. 2. Waterproof construction after the completion of the polymer mortar, forbidden perforated hole on the waterproof layer.
