  5. What Types of Rubber Waterstops...

Rubber waterstop is a waterproof material used in construction, water conservancy, tunnels, underground projects, etc. It is usually made of synthetic rubber with good weather resistance and corrosion resistance, and has good elasticity and tear resistance. Its function is to form a waterproof barrier in the building to prevent water from seeping into the building through the joints.

There are many varieties and specifications of rubber waterstops. According to the model, it can be divided into CB type rubber waterstop (embedded type with holes in the middle), CP type rubber waterstop (embedded type without holes in the middle), EB type rubber waterstop (externally attached type with holes in the middle). type), EP type rubber waterstop (externally attached type without holes in the middle).

How to choose the rubber waterstop?

When the waterstop encounters oil medium, nitrile waterstop should be used because nitrile rubber has better oil resistance.

When the waterstop corrodes media with weak acids and weak alkali, chloroprene rubber waterstop should be used because chloroprene rubber has better acid and alkali resistance.

When encountering the possibility of mold erosion, the mildew-proof performance of the rubber waterstop should be considered, and its mildew-proof grade should reach level 2 or above.

When the construction environment requires high anti-aging properties, EPDM rubber waterstops should be selected. For example, the anti-seepage cover sheet used on the panel dam is directly exposed to the sun, so EPDM rubber is selected.

Advantages of rubber waterstops

The advantages of rubber waterstops are that they are durable, corrosion-resistant, easy to install and maintain, and can accommodate joints of various shapes and sizes. At the same time, it can also be used in conjunction with other waterproof materials such as waterproof coatings, membranes, etc. to improve the overall waterproofing effect of the building.

Installation location of rubber waterstop

Rubber waterstops can be installed on walls, floors, roofs and other locations of buildings, and are often used in tunnels, reservoirs, sewage treatment plants, basements and other places. It can be fixed on the building through bolts, clips, glue, etc., and achieves a waterproof effect by tightly fitting with concrete, masonry and other building materials.
