The Installer’s Solution

ISCO has eliminated the hassle of aged and host pipe excavation. Special threaded sections of polyethylene pipe are inserted into the old sewer, forming one continuous, leak-free liner. Once anchored and sealed by grouting, the new system is virtually maintenance-free.

• No excavation and costly restoration
• No traffic diversions
• No interruption to service
• Better flow and chemical resistance
• Infiltration and exfiltration problems are eliminated

Buttress-Loc® is a leak-free, independent system featuring cost effective installation, improved flow and dramatically longer life. Buttress-Loc pipe is made from high-density polyethylene, known for its strength, flexibility, and outstanding chemical and corrosion resistance.
