What is the difference between a water stop and a water stop?

Both the waterstop and the waterstop are used to prevent the building from leaking, but the waterstop and the waterstop are very different in use and in principle.

1, rubber waterstop

Construction place: The water stop belt is often used for construction in places such as temperature shrinkage and settlement joints;

Water stop principle: The water stop belt is used to prevent and prevent water leakage. It utilizes the high elasticity of rubber and has very high deformability. It can be deformed under various loads and has certain strength and toughness. It can effectively leak and seep water in tightly sealed buildings.

2, water swelling water stop

Construction local: water-expansion water stop strip is mainly used in construction seams;

Water stop principle: After the water stop strip can touch the water, it can absorb water and expand. After the expansion, it can make a strict touch with the concrete, and can block the gap in the concrete to reach the effect of stopping the water;

The correctness of the construction and installation of rubber waterstops is the key to the use of rubber waterstops. We know that rubber waterstops are partially or completely buried in concrete during concrete casting. Since there are many sharp-pointed stones and sharp steel bars in the concrete, in the process of water stop positioning and concrete pouring, attention should be paid to the positioning method and the pouring pressure to avoid the waterstop being pierced. Since the tear strength of plastics and rubber is 3-5 times lower than the tensile strength, if the product is punctured, the ability of the product to resist external force will be greatly reduced, so special care should be taken during construction.
