PVC Waterstop

Definition

A PVC waterstop is a nonmetallic synthetic resin prepared by polymerization of vinyl chloride, inserted across a joint to obstruct the seepage of water through the joint.

Purpose

The purpose of a PVC waterstop is to prevent water from passing through concrete joints, ensuring the integrity and watertightness of structures such as foundations, retaining walls, and tunnels.

Examples of Use

• PVC waterstops are used in the construction of concrete foundations to prevent water ingress.
• Tunnels and dams incorporate PVC waterstops to maintain structural integrity and prevent leaks.
• Retaining walls and reservoirs use PVC waterstops to block water seepage through construction joints.

Related Terms

• Expansion Joint: A gap between sections of concrete that allows for movement and expansion.
• Sealing Compound: A material used to fill and seal joints or gaps.
• Waterproofing Membrane: A layer applied to surfaces to prevent water penetration.

Notes

PVC waterstops are essential for maintaining the waterproofing of concrete structures, ensuring longevity and durability. They are easy to install and provide reliable performance in various environmental conditions.
