Longsheng provide \ the Shaanxi rubber water-stop \ only 1.2 Drainage rubber water-stop manufacturer of water-stop material selection according to the following provisions 
 1.2.1 Under normal circumstances, multi-use natural rubber water stop. 
 1.2.2 When the case of weak acid, alkali, corrosive media, should use neoprene waterstops. 
 1.2.3 should be selected when the case of oil medium nitrile rubber water stop. 
 1.2.4 When possible case of mold erosion, should be considered mold rubber water-stop, their grades should reach more than two and two. 
 1.2.5 When the use temperature: -25 ° C ~ 60 ° C, selection of neoprene waterstops. 

 -35 ℃ ~ 60 ° C, use of natural rubber water stop. 

 -40 ° C ~ 60 ° C, use EPDM rubber water-stop. 
 1.3 the waterstops width and thickness of options to consider the following three factors 
 1.3.1 the level of deformation joint and vertical deformation 
 1.3.2 The water pressure 
 1.3.3 structure of the section size 
 (3) water-stop: (1). Buried in rubber water stop (2) backing with rubber water stop (3) (4) grouting steel side rubber waterstops waterstops and other forms. 
 Rubber water-stop construction and installation of: 
 The water stop pouring concrete pouring process, some or all buried in the concrete. In pointed stone and reinforced concrete, in waterstops positioning and concrete pouring process, should pay attention to the installation location method and pouring pressure to avoid the water stop was punctured. As the tear strength of rubber is 3-5 times lower than the tensile strength, so if the water stop was punctured will greatly reduce the water stop the ability to resist external forces. Therefore, in the construction of extra attention. Specific precautions are as follows: 
 1.1 in the steel banding and formwork, the water stop must be taken to a reliable fixed measures to avoid displacement occurred in the pouring of concrete to ensure that the correct location of waterstops in concrete. 
 1.2 fixed water stop, only perforated holes allow parts of the water stop shall not damage the body part. 1.3 
 Construction specifications for fixed water-stop shall be designed requirements, commonly used fixation methods: the use of a fixed set of additional reinforced; fixed special fixtures; wire and template fixed. Regardless of the fixed method. 
 Must be guaranteed the waterstops accurate positioning without damaging the effective part of the water-stop, convenient concrete pouring. 
 (5) after-sales service: 
 The water stop at the factory should be connected as a whole, as a result of the use of the environment or transport conditions and restrictions required in the field connection, we can always send someone to the field joints and to guide the installation. Site joints by hot press curing glue, and the appearance of smooth, bright and clean.
