Top 5 PVC Waterbar for Expansion Joints
PVC waterbars are essential waterproofing components used in expansion joints to prevent water leakage while allowing controlled movement in concrete structures. Expansion joints experience movement due to temperature changes, shrinkage, and structural loads, making the correct selection of PVC waterbars critical for long-term performance and durability.
Why PVC Waterbars Are Important for Expansion Joints
Expansion joints are designed to absorb movement without cracking concrete. PVC waterbars act as a flexible internal barrier within these joints, stopping water penetration while accommodating expansion and contraction. High-quality PVC waterbars ensure watertight integrity even under continuous movement and water pressure.
