We can provide various specifications of construction waterstop according to the customers' requirements.

Description of Construction waterstop:

Waterstops are made of elastomers of different characteristics. They are available in nitrile or flexible PVC (Vedaflex). Nitrile waterstops are characterised by a higher breaking elongation, excellent resistance to chemical agents as well as to ageing, and permanent elasticity that is comparable to that of rubber. Welded joints are very easy to produce. Flexible PVC waterstops are made from basic raw materials of high quality, but offer an economical solution.

Usage of Construction waterstop:

There are two normal types of waterstop: internal waterstops (A range) that are laid inside the concrete elements, and external waterstops (AA range) on the surface or periphery of the structures (bottom of formwork). These two types are used to waterproof concrete construction joints that are subjected to pressurised water. The AA waterstop is used on the faces to the ground where it is much easier to be laid. Waterstops can be welded to each other on site using a hot knife, but this can also be done in the factory where the conditions are strictly controlled.

Use method of Construction waterstop:

Construction waterstop reliable fixed measures necessary, banding steel and the mold. Prevent during concreting Rubber water-stop displacement occurred, to guarantee the water stop in the correct position in concrete. Only on allow part of the punched hole, for a fixed water stop. Bailey effectively waterproof parts shall not damage. Fixed methods are: to use the additional reinforcement fixed; Special fixture fixed; With lead wire and templates, etc. , no matter what fixed method for fixed method should be according to the design requirements of the construction specification and must guarantee the accuracy of the water stop positioning, no damage to water stop effective waterproof parts, convenient to cast concrete.
