PVC Waterstop

PVC Water Stoppers
PVC Waterstops are profiles based on specially formulated plasticized PVC composition. Waterstops are used in concrete masonry construction of hydraulic structures to safeguard from hydrostatic pressure and water seepage. Waterstops also withstand expansion or contraction of joints and take care of any deflection or displacement arising due to change in temperature or settlement of foundation eliminating danger of cracks. These are engineered a s Water Tight Seals in poured concrete structures.

Selection Criteria:
Selection of the waterstop depends upon the hydrostatic pressure of safe passage of seepage water. Where substantial expansion/contraction of joint takes place. Dumb Bells type should be used. In case differential settlement is expected and a firm grip in concrete is desired, serrated types should be used. moreover, following points should also be noted while selecting PVC waterstops.

    The overall width of the waterstop should not be greater than the thickness of the concrete.
    The distance form the face of the concrete to the waterstop must not be less than half the width of the watestop.
    The width of the waterstop must be atleast 6 times the largest aggregate used for satisfactory compaction.
  • Black/White length in 25meters or as desired colour & length.
Note: We can manufacture and design of PVC Stopper as per requirement.

Installation & Jointing:
Firstly one half of the waterstop is embedded in the concrete leaving the second half extended. Second half is also embedded leaving the centre bulb free from expansion and contraction. Care should be exercised in pouring concrete without misalignment the waterstop. Following joints may be fabricated by means of simple tools and heat fusion/welding.
