How to repair the leakage of the pipe through the floor in the kitchen?

(Summary description)

Information

In the actual use of the toilet, the kitchen, there will be a pipe water supply, drainage through the ground, these parts of the waterproof layer aging or failure, there will be the problem of water leakage.

Summing up such problems (non-pipe rupture and leakage), it can be found that the causes of leakage are roughly the same. The pipeline water supply between the kitchen for a long time, heat expansion and cold contraction and structural vibration produce cracks in the connection part of the pipeline and the floor, and crack the non-integrated waterproof layer.

And the pipeline in the installation, it is often reserved holes and then through the pipe, the root needs to be poured twice, so that the fine stone concrete tamping is not dense, will also produce gaps.

These are the hidden danger of water leakage, accumulated over time, leakage appears.

In view of this kind of health kitchen through the ground pipeline site leakage, can be divided from the front and the back of the two maintenance and treatment methods, combined with the needs of the actual operation, to make a comprehensive choice, today we mainly take a look at the front treatment of leakage method.

Front maintenance scheme

Remove the surface layer and binding layer around the root of the pipe from the front to the lower part of the original waterproof layer (demolition width is 300mm) Note: the original waterproof layer should be kept 150mm intact within the demolition range;

2. Pick the groove with a width of 20mm and a depth of 30mm at the junction between the pipe and the floor (if the loose area around the pipe is large, the groove cannot be removed);

3. Clean up the base surface, and then repair the base level with waterproof blocking and leakage king or cement mortar;

4. The root of cast iron pipe shall be polished by steel wire brush or PVC pipe grinding and rough;

5. Fill the sealant in the tank and cover the arc with the leakage king. Build a new waterproof additional layer on the repaired base surface. The waterproof additional layer should be lined with mesh cloth, whose plane matching width is 150mm, and the elevation erection height should be the same as the surface brick;

6. After that, brush the coating waterproof layer compatible with the original waterproof layer to ensure that the new waterproof layer should be connected with the original waterproof layer by 150mm, and the matching part of the old waterproof layer should be clean and free of dust;

7. Recovery the cushion (cement mortar layer) and apply the cement mortar protective layer on the new film waterproof layer;

8. After the curing of the waterproof layer, a 24-hour water closure test shall be conducted at the repair site.

9. After passing the water closure test, the binding layer and the surface layer are restored to the original state.

Comparatively speaking, from the front treatment through the pipe site leakage problem, the operation is more convenient, but for the new waterproof layer of material selection or need to be particularly careful: with ultra-high extension rate, super adhesion, aging resistance, non-toxic environmental protection, it is more reliable.

Health kitchen through the ground pipe leakage on the back of the treatment method we will introduce in detail in the following article.
