P.V.C WaterStop

” PVC Waterstop” produced by Capco are made of high-quality flexible PVC material and are used for waterproofing expansion and construction joints in concrete structures. These waterstops come in various sizes and are formulated and manufactured to provide high flexibility and long-term durability. Capco has taken the initiative to develop and regulate waterstop standards in Iran, first established in two parts: ISIRI 13277-1 and ISIRI 13277-2. The design of all dimensions, grooves, and holes in the manufactured waterstops by Capco is based on the first part and other technical requirements such as elongation increase during aging (elongation) according to the second part are controlled.

Properties and Effects:
  • • A wide range of widths and thicknesses according to construction conditions.
  • • Compliance with international and domestic standards.
  • • Availability of welding equipment at the project site.
  • • Provision of clamps for ease of installation at the desired location.
  • • Long rolls to minimize welding joints.
The usage of the PVC Waterstop:
  • • Water tanks, water towers, and sewage reservoirs
  • • Water pools and reservoirs
  • • Dams, culverts, canals, and spillways
  • • Bund walls around fluid-retaining reservoirs
  • • Underground parking lots, tunnels, and underpasses
  • • Retaining and barrier walls, roof slabs
  • • Other water-contact structures with expansion and construction joints.
The instruction to use the PVC Waterstop:
  • If a waterstop has undergone deformation or damage that affects its functionality, it should not be installed.
  • Before installing waterstops, ensure they are free from warping, wrinkles, cracks, or any other deformities.
  • Any deformation occurring during transportation or storage of external waterstops should be corrected using tension and thermal methods on a smooth surface.
  • Waterstops should only be installed when the air temperature is above or below ±0 degrees Celsius.
  • Placement of external waterstops: They should be free from contamination and freezing. If necessary, they should be cleaned before concrete pouring (removing any residues from workshop operations like dust, sand, concrete leftovers, oil, grease, snow, ice, etc.). This is especially crucial for external waterstops installed on the structure’s floor.
Physical and Chemical Specifications of the PVC Waterstop:
  • Waterstops produced by Capco are made of highly flexible PVC material with exceptional quality. They are utilized for waterproofing expansion and construction joints in concrete structures.
Maintenance and Safety:
  • • Proper storage and handling of waterstops in the workshop must be carried out meticulously. Immediately inspect the shape and dimensions of the waterstops to ensure their completeness and integrity.
  • • Before installation, waterstops should be stored in a protected area, placed on pallets, and shielded from contamination or damage.
  • • Storage in summer: Particularly in the summer season, waterstops should be shielded from direct sunlight. When the outside temperature is high, they should be transported covered and, without exerting stress, taken out of the covering for installation.
  • • Storage in winter: Ideally, waterstops should be stored covered, and before installation, they should be kept in a warm room for at least a day to facilitate their handling and minimize potential damage during transportation. When hitting the external waterstops, extreme caution should be exercised to prevent them from becoming loose when striking the molds. If necessary, molds in these areas should be opened later.
