Top 5 PVC Waterbar for Water Tanks
Water tanks require robust waterproofing to prevent leakage and protect stored water from contamination. PVC waterbars are used within construction and expansion joints of water tanks to form internal seals that stop water from escaping and resist hydrostatic pressure. Choosing the right PVC waterbar is key to ensuring long-lasting watertight performance.
Why PVC Waterbars Are Used in Water Tanks
Concrete joints in water tanks can become pathways for water seepage if not properly sealed. PVC waterbars act as flexible internal barriers embedded within these joints, preventing water penetration while accommodating controlled movement due to temperature changes and loading.
- Stops water leakage at construction and expansion joints
- Resists hydrostatic pressure from stored water
- Offers flexibility for structural movements
- Provides long-term waterproofing protection
