Code of Practice for Waterproof Angle of Yin and Yang

The base at the corner of Yin and Yang of the waterproof layer should be made into a 45 fillet or a splay according to the requirements, and the splay foot is 50mm long. Due to the stress concentration at the joint, it is often destroyed earlier than the large-area waterproof layer. Therefore, additional layers are added to these parts, and the additional layers can be laid with coil strips.

In the internal corner, it is usually paved with full stickers, and in the external corner, it is often paved with empty ones. The width of the additional layer is as stipulated in the design, and it is generally advisable to paste 250mm on each side.

Yin and Yang Angle additional layer coil to cut into graphic shape, according to the graphic crease construction.

Methods of waterproof and leakage-mending for houses

1, cracks and water leakage

For example, the temperature control of concrete in construction is not in place, the maintenance is not in place, and the settlement joint is not standardized. There will be cracks and water leakage in the house. If this is the reason, you can clean up the concrete with bad joints first and repair it according to the construction requirements, or pour concrete according to the construction standards and make settlement joints according to the regulations.

2, the waterproof layer leaks

The waterproof layer is damaged, or the quality of the materials used is not good, which will also cause leakage of the waterproof layer. The leakage caused by this reason requires us to remove the protective layer such as tiles on the wall in the hourglass area, do a good job in waterproof engineering and do a good job in water closing test. If there is no problem, we can lay tiles.

3. Not fully compacted

If workers don't tamp the concrete, there will be empty drums and other phenomena, which will lead to moisture and water seepage in the wall. If this is the reason, it is necessary to eradicate the leaking wall or ground, choose the appropriate concrete installation specifications for construction tamping, then pour, finally waterproof the wall or ground, and finally lay tiles.
