Applications:
✔ Water containment structures: Reservoirs, dams, tunnels
✔ Water/wastewater systems: Pools, canals, sewage treatment plants
✔ General waterproofing: Prevents water penetration at concrete cold joints and expansion joints
Key Advantages:
– Easy installation
– Concrete-compatible lifespan
– Resistant to concrete alkalinity
– High tensile strength (15 N/mm²)
– Exceptional flexibility (400% elongation)
– Secure concrete bond
– Leak-free splice connections
– Diverse size/shape options
Product Selection Guide:
| Type | Profile | Use Case |
|———-|————|————–|
| Flat (E-Type) | Solid PVC strip | Construction joints (embedded between concrete pours) |
| Bubble (O-Type) | Center-weep hollow profile | Expansion joints (accommodates structural movement) |
Sizing Principle:
– Waterstop width should match joint thickness.
– Low-pressure applications: Thin profiles
– High-pressure/high-head applications: Thickened profiles
Installation Instructions:
For E-Type (Flat):
1. Embed 50% of the strip in existing concrete; remaining 50% bonds with new pour.
For O-Type (Bubble):
1. Position centered over the joint** after initial concrete placement.
2. The hollow core must align perfectly with the joint gap to allow expansion/contraction.
Critical Notes:
⚠ Use PVC waterstop clamps for positioning—never puncture (causes stress fractures).
⚠ Splicing: Overlap joints or thermally weld using a dedicated PVC heat welder.
