Basic Use: "A Waterstop is usually a section of flexible waterproof material placed at any joint in concrete to prevent the passage of water."


Joints in concrete structures, one side of which is subject to hydrostatic load, are generally provided with Waterstops bridging the joints and embedded in the concrete on either side. In concrete joints where expansion and contraction cause the joints to close and open, the Waterstop must be designed to accommodate itself to movement. The primary reason for specifying Rubber Waterstops rather than metal or PVC is their superior performance in withstanding shear movements and resisting hydrostatic pressure.


Rubber Waterstops will have ultimate elongation of 450% (ASTM D 412-75) and will continue returning to near original shape after repeated movement. They have very low compression set and perform well at low temperatures.


The system features sleeve type fittings that provide fast positive splicing and precise. Waterstop alignment. Fittings are manufactured from the same elastomers/polymers as the Waterstop.


Typical installations include: sewerage plants, water filtration plants, aqueducts, reservoirs, locks, tanks, channels, swimming pools, culverts, tunnels, bridge decks and abutments, roofs, dams, foundations, mine shafts, retaining walls and any concrete structure requiring watertight joints


The necessity of installing water stop:

In many countries in the design of large scale engineering construction, civil engineering, water and soil structure has a certain scale, and there is waterproof and shockproof requirements, so use and install rubber waterstop is effectively solve various problems encountered in the above project.

What are the characteristics of the rubber water stop?

The following are the characteristics of the rubber water stop:

1.In the process of product installation, the interface is simple, safe and reliable. In the field using heat welding method or heat curing method and docking, to make sure that  the water stop lap seam is quality, safe, reliable, and in order to make the waterproof quality of the construction joint/expansion joints be more perfect, more secure and reliable guarantee.

2.Rubber sealing strip can be carried out daily detect and repair. Through a preset grouting pipe to water leakage detection, If because of the waterstop quality or construction quality and other reasons, resulting in construction joint leakage, through the grouting pipe grouting repair is the most effective and rapid economic. And it can make the waterproof quality of the construction seam / deformation joints be more safe and reliable durable.

3.This product operation is simple, economical and practical. Water stop belt is provided with a mounting hole, easy to installation and accurate positioning. Grouting pipe can be reused, detection and repair has the advantages of simple operation, to avoid the traditional drilling and grouting repair, and it has good effect and low cost. Rubber water stop with is that we can use the rubber itself has a high elasticity and compression deformation characteristics, deformation is generated under various loads, so as to effectively fastening seal, to prevent the leakage of construction, water seepage and cushioning, thereby improving the construction / expansion joint water-proof safety coefficient. If there is a leak, by grouting, effective and rapid repair. Water quality is reliable and no recurrence. The comprehensive cost is the most economical and it completely solve the traditional water stop weakness.

The scope of application:

Generally used in basement wall and the construction of the late poured band , rubber water stop belt is mainly used for one of the basic engineering cast-in-place concrete when in construction joints and deformation joints and concrete structure , such as underground facilities, tunnels, aqueducts, dams, liquid storage structures and so on.

Processing procedures of rubber water stop 

raw materials---1st pressing---2nd Pressing & cutting---3rd inner hose shaping

with the model---4th inner hose frozening(-19°C)---5th weaving/Twining for

several times(as request)---6th wrapping---7th vulcanization for 40-50 mins--

-8th unwrapping---9th model extrusion---10th testing---11th packaging---12th

finished products



First, cut the waterstop ends square. Brush adhesive onto cleaned, butted surface of the waterstop and fitting, assemble, hold in place, allow to dry.

Installation of Waterstop involves split forms. In the first pour the waterstop is held in place with blocks or other suitable arrangements on the outside of the split form (away from the concrete which is to he poured).

After the first pour has set up, the split forms and block are removed. When the adjoining pour is made, care should be taken to support the waterstop.
