Concrete waterproofing: This PVC strip is designed with the aim of sealing executive and expansion joints and is produced and supplied in different dimensions and shapes.
Uses of concrete stratification
Construction of reservoirs, dams and tunnels
Construction of pools and canals
Sewage and water treatment plants
Generally prevent the passage of water in concrete cutting sites (executive and expansion joints)
Advantages of concrete stratification
Easy to install
Its efficiency is equal to the life of concrete
Resistant to alkaline reactions of concrete
High tensile strength
Extraordinary flexibility
Sufficient engagement with concrete
Full connection without leakage to each other
Variety of sizes and shapes
Select the type and size of concrete stratification
PVC waterstops are produced in two types: under (E) and hollow (O). The flat type is used for executive and concrete cutting joints and the hollow type is used for expansion joints and joints. Usually, the width of the waterstop should be equal to the thickness of the installation section, and depending on the pressure on the seams, the shape of the waterstop will be determined.
Method of installation and stratification of concrete
Flat water stops (E) should be used in the predicted locations of concrete cutting, half of the width of which will be in the old concrete and the other half in the new concrete.
Cavity (O) water stops in the predicted locations of the expansion joints and June should be placed in such a way that the waterstop cavity is completely in the joint after concreting the first and second sections to have sufficient resistance during expansion and contraction of the structure. Have the necessary tension and pressure.
To fix the waterstop in its places, use waterstop clamps and they should never be punctured because the waterstop will rupture due to the change of tension in the place of the hole.
To connect the waterstops to each other, in addition to overlapping, use a waterstop thermal welding machine.
