What should be paid attention to during the construction and installation of water stop?

There are many sharp stones and sharp steel bars in concrete. Because the tearing strength of plastic and rubber is 3-5 times lower than the tensile strength, once the water stop is punctured or torn, the crack will expand without great external force. Therefore, in the process of positioning the water stop and pouring concrete, we should pay attention to the positioning method and pouring pressure to avoid the water stop from being punctured.

How to ensure the quality of externally attached water stop;

1. The incoming materials must have the product certificate (or material inspection report), a copy of the business license with official seal and the material re-inspection report.

2. When transporting materials, avoid direct sunlight, contact with heat sources, oils and harmful solvents, and avoid heavy pressure on finished products.

3. Construction personnel should strictly check whether the material specifications and appearance are defective.

4. The construction shall be carried out by an enterprise with professional waterproof qualification, and the operators shall hold relevant certificates and be operated by experienced construction personnel.

5. When positioning the water stop, it must be kept flat and cannot be turned over or kinked. If it is found that there is no proliferation, it should be adjusted in time.

6. The water-stop paste position must be firm, and two parallel water-stop joints should be staggered by 30cm.

7. When pouring concrete on the water stop, it must be vibrated and compacted, so that it can be well combined with concrete.

8. Before pouring concrete, remove the sundries in the water stop tank and rinse with clear water to ensure the tank is clean.
