Water Stop | Best Types of PVC & UPVC Water Stop by iChem Egypt 2025
What is a Water Stop?
When constructing any concrete structure — whether a water tank, treatment plant, or tunnel — waterproofing is a crucial element to protect the building from leakage and corrosion.
That’s where the Water Stop comes in. It’s a flexible strip made of PVC or UPVC, installed inside the concrete joints during casting to completely prevent water passage through the joint.
At iChem Egypt, we provide IsoFlex PVC Water Stop, manufactured from the finest European raw materials. It offers exceptional flexibility, heat and moisture resistance, and outstanding durability under high water pressure.
Importance of Water Stop in Protecting Structures
Installing a water stop is not just a technical step — it’s a key factor in ensuring the long-term durability of any water-exposed structure.
It prevents water from penetrating the concrete, protecting the steel reinforcement from corrosion and significantly extending the lifespan of the structure.
Main applications include:
Underground and overhead water tanks
Pumping and treatment stations
Tunnels and box culverts
Swimming pools and water reservoirs
Horizontal and vertical concrete joints

Proper Installation of Water Stop
Installing a water stop requires high precision and should be done during concrete casting:
Place the strip at the center of the construction joint.
Use metal clips or heat welding to secure it properly.
Ensure the fins are embedded into the concrete to prevent leakage.
Inspect welding points before pouring concrete to ensure complete sealing.
