Floor Water Seepage Treatment Measures

I. Overview and cause analysis:

Tianmenyuan 16 # Floor 2 ~ On the sixth floor, local water seepage occurs, and leakage can be observed from the bottom of the plate. On-site water seepage marks show irregular cracks on the bottom of the plate. It can be analyzed that the water seepage cracks are the dry-shrinkage capillary cracks generated during the concrete hydration and solidification process, and non-structural force deformation occurs, it has no impact on structure security.

Ii. Possible Consequences

This water seepage occurs because we only use ground cement mortar to find the flat layer in our contract, and the ordinary floor is not waterproof. This will cause water seepage on the floor after being handed over to the household during the decoration and use process, as a result, various disputes and disputes may cause unnecessary economic losses and image losses to all parties. Therefore, it is particularly important to deal with this situation.

Iii. Solution

The best way to deal with water seepage is to make water treatment on the floor. Based on the actual situation and the characteristics of various waterproof materials, we plan to use 2mm thick cement-based capillary crystalline Composite Waterproof Coating for waterproofing of the floor. Perform the following steps for waterproofing of the floor:

1. Clean the Floor Concrete Base Layer

Before waterproofing, all the debris such as mortar and floating slurry on the concrete floor should be cleansed and cleaned with water, non-design reserved holes such as the laying hole and reserved hole of the Concrete Pump tube reserved on the panel should be blocked by expanded Fine Stone Concrete first.

2. Brush cement-based waterproof coating

Before the construction of waterproof coating, we should first conduct a comprehensive inspection on the panel surface, and confirm that the debris such as float on the panel has been cleaned up and there is no obvious water.

Apply waterproof coating should be carried out in different rooms. Apply the paint in one direction for the first time. For example, apply the paint in north-south or east-west directions. Apply the waterproof coating evenly and do not leak the paint. No bubbles or holes may exist after the painting, after the first click, you can apply the paint for the second time. The direction of the second click is the same as that of the first click. Other Panel waterproofing processes are performed in sequence.

After two times of Waterproof Coating Treatment, the thickness of the waterproof layer should be checked. If the thickness is less than 2mm thick, you should fill the brush once again to meet the requirements of 2mm thick.

3. After the waterproof paint is painted, in order to prevent cracks on the surface layer of the dry-drying and water-loss coating, the waterproof floor should be watered and maintained to keep the waterproof paint surface moist.

Iv. processing result test

After the waterproofing treatment and maintenance are completed, the treated floor should be tested with water and the treatment effect should be checked. The specific method is to spray water on the floor, and there is obvious water on the floor, 2 ~ 3 hours later, check whether there are signs of leakage at the bottom of the plate. If there is water seepage, proceed with the above method. Only when water seepage does not occur can the ground leveling layer be constructed.
