Anonymous users2024-01-23The main functions of toilet backfill are: 1. The backfill has a certain water content. 2. The backfill should have a certain structural force, not too loose, and it is easy to sink after the backfill.
There are 3 types of materials for bathroom backfilling:
1. Slag. 2. Brick slag. 3. Perlite or ceramsite. Toilet drains and other pipes should be mated with bricks!
These three materials have their own advantages and disadvantages, 1. Slag is the best of these kinds, with better water content and a certain structure, but now it advocates environmental protection, and there is basically no cinder boiler in Changsha, so the material is relatively difficult to find. Disadvantages, slag contains sulfur oxides, and water will form sulfuric acid later, will have a certain corrosive effect on iron, sewer pipes with iron parts of the bathroom is best not to use slag backfill.
2. Brick slag is a kind of backfill material that can be found now and has relatively good performance. The disadvantage is that the water chestnut has a certain destructive effect on the waterproof layer, and it should be broken when used to minimize the destructive force per unit area.
3. Perlite, the texture is too loose, easy to cause sinking, and it is not recommended. If the original bathroom does not leak, and the waterproof layer is not damaged below, it can be directly backfilled, backfilled to the part close to the plane, and tamped with cement mortar. Then paste the wall tiles.
After sticking it to about 30 cm above the ground (the shower area is strengthened and heightened), then do the waterproofing of the wall and the ground, focusing on the waterproofing around the corners and pipes. Test the waters again. If there is a water leak before the backfill, we must urge the property to rectify it, and if you are not at ease, you can renovate it when you decorate it, and ask the decoration master to strengthen the waterproofing again, and then do the backfill.
