During construction, the grass-roots treatment of the construction site should meet the requirements of national standards, and the construction surface should be dry and hard, and there should be no uneven defects such as hollowing, sanding and cracking. The hot-melt method requires that the bottom of the coil be fully melted, while the cold-stick method is generally sticky, and all the important parts are full of sticky.
Extended data:
1. Before waterproofing membrane construction, leveling is required, and the surface can't have any sundries, including Mingshui and oil stains, and the construction must be sunny. In case of rain or just rain, the construction must be postponed for several days.
2. Waterproof membrane has high requirements for the construction environment. No matter which method is adopted, it should be kept in a dry environment, and construction should not be carried out in an environment below zero as far as possible, otherwise poor adhesion will easily occur. If necessary, protective measures should be taken.
According to experts from Qijia. Com, because the waterproofing membrane needs to be pasted in one piece, it is easy to have bubbles. If it is not handled in time, it will easily affect the waterproof effect. Therefore, when pasting waterproofing membrane, it is necessary to discharge bubbles while constructing.
4. During the transportation and construction of waterproofing membrane, attention should be paid to avoid damaging the membrane, which will bring unnecessary troubles and losses, especially if it is not found, it will be very troublesome to rework after it is put into use.
