? Solutions to basement water seepage:
? 1. Water seepage at the root of the wall: First, when building the basement wall, ensure the fullness of the cement mortar filling the wall , to prevent water seepage from the joints of the bricks; secondly, before plastering on both sides of the wall, the roots should be cleaned to ensure that the density of the root plastering is qualified. If necessary, eight figures should be made at the internal corners where the two sides of the wall meet the foundation. secondly, make sure that the upper elevation of the waterproof coating on both sides of the wall is lower than the indoor elevation of the basement. When laying the flexible waterproof layer on the wall, special treatment should be done on the root of the wall to ensure that the laying is qualified.
? 2. For deformation joints: the inside of the joint is often sealed with insulation foam board, and then asphalt linen is used to seal it, and both sides are coated with two cloths and three coats of ointment. To ensure the deformation of the deformation joints and at the same time ensure the waterproofing effect, a protective wall should be built outside the waterproof layer with a width 120 wider than each side of the waterproof layer, and the gap in the middle of the waterproof layer of the protective layer should be filled with cement mortar. To prevent the waterproof layer from being damaged during backfilling of the foundation pit.
? 3. The pipe passes through the wall hole in the basement. After the pipe is installed, the surrounding area is compacted with dry hard cement mortar or plain cement, and then waterproof coating is applied on both sides. After the waterproof coating dries, Apply polyurethane waterproof coating twice within 35mm of the outer diameter of the pipe.
? 4. When the heating pipe passes through the wall hole in the basement, the thermal expansion and contraction of the pipe must be considered. After the pipe installation is completed, use asphalt and linen to pound the wall hole firmly, and apply cement on both sides of the wall. For mortar, apply the polyurethane waterproofing membrane twice.
? 5. For water seepage in the scattered water parts, the wall waterproof coating should be about 150mm higher than the scattered water to ensure that the top side of the feet is tightened to ensure that the waterproof layer of the scattered water parts is not broken, and the waterproof layer of the scattered water parts should be well connected with the water. Fill the cracks at the feet with ointment; in order to ensure the waterproofing effect and prevent water seepage, the basement wall needs to be built with cement mortar, and the mortar joints must be full.
? 6. Water seeps through the joints of the wall. Before masonry, wet the surface of the bricks with water and then lay the cement mortar; when laying the bricks, ensure that the cement mortar of the mortar joints is dense and full, and the mortar joints should be outlined; When plastering, check the plaster joints first, and then fill them if there are any loose spots.
7. In terms of external factors, it is necessary to ensure that the outdoor road drainage is smooth, and at the same time, ensure that the outdoor road is more than 20mm lower than the minimum standard for scattered water. The outdoor drainage pipes must always be kept clear and not damaged. To prevent external water seepage; the water stored in the warm water pipe trench must be cleared immediately. The control of outdoor water seepage sources to avoid the occurrence of water seepage sources is also a very important measure to prevent basement water seepage.
