Basic use: PVC waterstops are designed for use in concrete joints subjected to hydrostatic pressure.
Embedded in concrete, waterstops span the joint, forming a continuous,watertight diaphragm that prevents the passage of fluid.
In concrete structures, waterstops must be designed to accommodate joint expansion, contraction and other lateral and transverse movements. In addition to accommodating expected movements, the waterstop material must also be compatible with the concrete system and the liquids or chemicals contained in the structure.
Typical concrete structures requiring waterstops include: water and waste water treatment plants,reservoirs, locks, dams, canals,aqueducts, tunnels, storage tanks,foundations or any concrete structure where liquids are to be contained or controlled.
