(1) Lay a coiled material waterproof layer on the bottom plate. After the construction of the retaining wall is completed, lay the facade coiled material directly on the outer wall of the retaining structure, and then take protective measures. The biggest advantage of this method is that after a long time, the concrete of the wall will slowly dry, which can effectively prevent indoor humidity.

⑵ Complete the masonry of the retaining wall, then spread coiled materials on the retaining wall and bottom pad, and after the waterproof layer is completed, pour the concrete of the retaining structure. The only disadvantage of this method is that the construction conditions are limited, and it is a waterproof construction method that has to be adopted.

2. How to make the kitchen waterproof:

(1) Generally, the ground is uneven, and the kitchen base should be repaired before waterproofing, especially in the corner of yin and yang, and the uneven place should be leveled. You can shovel out the protruding cement slag and sundries with a shovel, and repair and smooth the sunken place. If there are cracks or water seepage, it needs to be plugged and repaired.

(2) After the ground is repaired, it is also necessary to ensure that the base surface is free of any dust, particles and garbage, so it can be cleaned with water before construction, as long as the surface is wet and there can be no Mingshui.

(3) Make the ground waterproof first, so mix the waterproof coating on the ground first. Pour the waterproof paint into a plastic bucket according to a certain proportion, first pour the paint emulsion, then pour the powder, stir it evenly with a blender, stand for three minutes after it is in a particle-free state, and use it after eliminating small bubbles.

(4) You can start brushing waterproof slurry. First of all, we should focus on painting some special areas in a small scope, especially around floor drains, pipes and walls. Then other areas can be painted for the first time in a large area. After the brush is soaked, the paint sticks to the brush in one direction, and the thickness of the paint film is within 1mm, which is easy to dry and not easy to bubble and crack. After drying, it can be painted in the cross direction for the second time to avoid brush leakage, and the closed water test can be carried out the next day.

5] The kitchen space also needs waterproof measures for the wall, the height of which is about 180cm, which can prevent the faucet from soaking the wall in water. Its practice is consistent with the ground waterproof practice, the only difference is that the waterproof slurry is different, and the special coating for wall surface should be used.
