Hengshui expansion of the seal specifications] [the Shijiazhuang product type water expansion of the seal industry-leading 
 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. Fixed method should be of 1.3 waterstops design requirements of the construction specifications, fixed: the use of a fixed set of additional reinforced; fixed special fixtures; wire and template fixed. Regardless of the fixation methods, 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.
