Installation Guide

Pre-Embedding – Anchor in first concrete pour using tie wires.

Joint Welding – Use oxyacetylene torch for continuous seams.

Concrete Protection – Prevent direct contact with alkaline additives.

(Pro Tip: Pair with Bentonite swell strips for redundant sealing!)

Why Engineers Prefer Copper Waterstops?

✔ Proven in mega-projects (Three Gorges Dam, Channel Tunnel)

✔ Zero maintenance – No replacement needed

✔ Superior ROI despite higher upfront cost
