Waterproof construction precautions

Waterproof construction precautions:
1, before the waterproof construction, we must first clean the debris and dust in the construction site, and the depression should be levelled with cement mortar in order to carry out waterproof construction.

2, the intersection between the water mouth and the ground should also be handled well, these fine points, can not have a lucky mind, otherwise there will be leakage after the construction, too late.

3, the joint between the wall and the ground, it is easier to be ignored, in the construction time to pay attention to, you can use the corner wipe and fingers to smooth and clear, these places are the most prone to water seepage.

4, the wall must be waterproof treatment, the wall waterproof is done before the wall tile.

5, the key step in the construction is the base surface treatment and later protection. The foundation is not handled well, just like the foundation of the building is not done, how everything else is empty talk. In addition, the later stage is not protected, the waterproof layer is damaged, and it can not play a waterproof role.

6. The waterproof layer should be scraped in accordance with the principle of the first detail (pipe root, water leakage hole, etc.) after the large surface (wall and ground). Yin and Yang Angle should be made into a circular arc, large area waterproof construction, according to the design requirements in the groove embedded in the sealing material, in the gutter, cornice, Yin and Yang Angle, pipe root and other nodes, the first brush paint twice.

7, waterproof paint full coating, no omission, and the base is firmly bonded. There is no bubble, no crack, no delamination, the surface is flat, the height of the rolling part is basically uniform, and the thickness must meet the requirements of the product. The waterproof coating construction shall be carried out step by step according to the time schedule specified in the instruction manual. After the completion of the construction process, other subsequent engineering construction shall be carried out.

8, generally, the thicker the better, but the waterproof as long as the national acceptance specification of 1.5mm thickness can be.

9. The grooves of the water pipes in the wall should also be waterproof. When pipelines and floor drains pass through the floor, the waterproof layer around the holes must be carefully constructed. The pipes buried in the wall should be chiseled into grooves larger than the diameter of the pipe, the grooves should be plastered smooth, and the waterproof coating should be brushed.

Tip: If the original drainage and sewage pipes and floor drains are changed during the renovation, it is necessary to strengthen waterproof measures around.
