Rubber sealing strips classification

Based on usage, rubber sealing strip can be classified as buried water-stop and back stick type rubber water-stop. According to the form appearance, it can be divided into CB-type water stop (refers to the middle hole of buried waterstop), CP-type water stop (refers to the middle of nonporous buried water stop), EP-type water stop (also known as externally bonded water stop or backing with water stop, refers water stop to posted outside the middle of no pass water stop),

EB-type water stop (also known as posted outside water stop or backing with water stop, refers to water stop posted outside the middle of the hole).

Rubber sealing strip model specification

Rubber sealing strip common specifications are 300 x 6 mm, 300 x 8 mm, 300 x 10 mm,350 x 8 mm, 400 x 10 mm, etc. And the model commonly used is buried type 651.


Rubber water-stop selection

Structures should be based on the level of importance, the amount of deformation and pressure, so that the water-stop can be used properly.

a.Under normal circumstances, we generally advise you to choose the natural rubber water-stop.

b.When it comes to weak acid and alkali corrosive media, you should use neoprene rubber water-stop.

C.When it comes to oil medium, you should use nitrile rubber water-stop.

d.When the application might be eroded by mold, water stop mildew should be considered. And at this time, the water-stop you choose should reaches level 2 and 2 above.

e.According to the piratical using temperature.

-25 °C - 60 °C, it is better to choose chloroprene rubber water stop.

-35 °C - 60 °C, it is better to choose natural rubber water stop.

-40 °C - 60 °C, it is better to choose EPDM rubber water stop.

f.When it comes to waterproof sheet materials such as welding, you should use its same molecule synthetic resin type water stop (EVA, PE, ECB, HDPE, PVC).


Quality requirements of seating appearance


Rubber sealing performance parameters



1.Banding, rubber/metal only be applicable to water-stop with steel plate.

2.If other special needs when appropriate may be negotiated stingy inspection, as appropriate, according to user needs assessment mold testing, but its antifungal properties should be equal to or greater than 2.

Rubber sealing strip application scope and standards

Rubber sealing strip with water swelling rubber water can be applied to underground structures like dams, reservoirs, swimming pools, roofing and other building materials and structures used in the deformation joint waterproof. Because concrete structure has become one of the basic part of the engineering, underground facilities, tunnels, culverts, water aqueducts, dams, and rubber sealing strip is mainly used for concrete cast in the construction joints and deformation for ensuring life of the project construction. So it is very important in construction.

Water-stop complies with GB18173.2-2000 standard for polymer waterproof material - water stop production. According to users' piratical requirements in different projects, different parts, different slopes, our products can equipped with cross. What's more, the angle of inside and outside rubber water-stop connector products can also be applied to any special designs.


Construction and installation of rubber water-stop

In construction, some or all of the rubber water-stop is buried in the concrete during pouring process. Because there maybe are many sharp corner stones and sharp steel heads in concrete, we need notice its installation positioning method and pouring pressure during water-stop position and concrete-pouring process to avoid water-stop punctured. Due to the tear strength of rubber/PVC materials is lower than strong stretching by 3-5 times, its product ability to resist external forces will significantly reduced if waterstop punctured. So in order to keep effective of waterproof function, specific matters tips in construction as follows:

A.Rubber water-stop can't resist long time outdoor exposure, should prevent from the rain, do not contact with strong polluting chemicals. It's better to keep products in stored places where temperature changes from -10°C to + 30°C, and relative humidity from 40% to 80%.

B.During transportation and construction, you should prevent the products from damage of the machinery or steel bar. The storage and transportation of finished products should be taken in the flat circumstance, don't increase the pressure.

C.In construction process, the product must be installed properly, avoid the displacement during concreting and guarantee the water stop in the correct position in concrete.

D.The common methods of fixing water-stop: using the additional reinforcement fixing, special fixture fixing, lead wire and fixed templates fixing, etc. If you want to punch, only need to select edge part of the installation area, shall not damage other parts.

E.When ordering the products, according to the engineering structure, calculation length of good product design, you should provide us drawings. Because the heterotypic structure should have the drawings and we can check the hose connection in the whole part. Because of the production process or transportation limitation, needing connecting at the scene, you should adopt the method of the electric heating plate vulcanizing bonding or cold bonding (rubber water-stop) or welding (plastic water-stop) method. And if you still have difficulties in construction process, our company can send technical personnel on-site guidance.

Notice during transportation and storage

During transportation and storage, products should avoid direct sunlight, should not contact with heat, oil and hazardous solvents. Do not affect the quality of rubber in contact with the substance. Finished product should be taken straight flat, do not increase the pressure. Storage areas best kept from -10°C to + 30°C, relative humidity 40% - 80%, and should be kept clean.
