Waterstop

Definition

A Waterstop is a synthetic rubber strip used to seal joints in concrete foundation walls.

Purpose

The purpose of a waterstop is to prevent water from passing through joints in concrete structures, such as foundations, retaining walls, and tunnels. It ensures the integrity and waterproofing of the structure.

Examples of Use

• Foundation Walls: Installed in construction joints to prevent water infiltration.
• Retaining Walls: Used to seal joints and prevent water pressure from causing leaks.
• Tunnels: Provides waterproofing for joints in underground structures.

Related Terms

• Sealant: A material used to block the passage of fluids through a surface or joint.
• Concrete Joint: A deliberate break in a concrete structure to allow for movement and prevent cracking.

Notes

Waterstops must be correctly positioned during concrete pouring to ensure effectiveness. They come in various profiles and materials to suit different applications and environmental conditions.
