Rubber water swelling rubber waterstops

1. General Introduction

Awaterstopis an element of aconcretestructure, intended to prevent the passages of fluids (such as water) when embedded in and running continuously through concrete joints.

Waterstops are frequently manufactured from extrudedplasticssuch as flexible polyvinyl chloridePVC,polyethylene(PE) orthermoplasticvulcanizate rubber (TPV); formed metal such asstainless steel,copper, or carbon steel; or extruded thermosets such as natural rubber,styrene-butadienerubber, orneoprenerubber.

2. Characteristics

The waterstop belt can tight the airproofing, prevent making water, water penetration, shock absorption and cushion, for the characteristic of high flexibility and compression deformation.

There have to be some construction slot, sedimentation slot, transmutation slot for some reason of can not keeping affuse, or the transmutation of geology, or the thermal expansion and thermal contraction of the concrete for the reason of temperature, so it must to fix the waterstop belt to prevent leakage.

3. Application

The underground projects of the retaining dam, reservoir, metro, culvert, tunnel lamp. In those projects, it can be prevent from that thegroundwater(or out of bounds water) spill over into the buildings structureand also can preventthebuildings water leakage to the outside world.

remark
1 rubber and metal bonded items apply only to the edge of waterstop which include steel.
2 demand and supply can discuss about the question if there is other special needs, such as mold assessment test, but the anti-mildew properties should be equal or higher than two grade.
