Sewer Products

Link-Pipe offers innovative no dig sewer line repair solutions for efficient and reliable repair. Our Stainless Steel 316 Sleeves are designed for short repair to structurally repair the host pipe. 

We designed our system to be easy to install, need very little equipment and most repairs can be carried out in a live sewer operating condition. Link-Pipe's technologies does not require digging or external point repair. 

Standard Link-Pipe's sleeve is made of stainless steel expandable cover covered with sealing material. For brittle pipes, our sleeves have limit straps to prevent over-expansion of the Installation pressure. In flexible pipe situations, when sometimes exact I.D. of the host pipe is unknown, our sleeves carry a Variable Diameter Locking Mechanism that is designed to have +/- 1/2" of tolerance.

Culvert Products

Water Main Products

For water main repair application, a sleeve called Hydro Seal™ is used. Hydro Seal™ can be applied to: seal joints and breaks, isolate lead in joints and seal holes. 

Installation in a cleaned pipe can be made through opening left by removing valves.

In a built-up city, any excavation through existing surface and underground structures becomes not only very costly, but also very disruptive to social activities. Link-Pipe techology is designed to offer the liberty of choosing most suitable locations for excavated entry if needed and in case of water mains, valve chambers offer excellent predetermined access points. By temporarily removing the valves, necessary access becomes available.

End Sealer Products for CIPP

Prior to CIPP relining, our Repair Sleeves can repair structurally missing or deteriorated/damaged pipe and create a "re-newed" round host pipe.

It enables CIPP installation using a thinner liner and improves it to eliminate premature repairs or replacement. The ends of CIPP liner can be permanently sealed with our End Sealers™. De-lamination at the ends of the liner and infiltration from the separation between liner and host pipe will no longer be a concern once the End Sealers™ are locked into place.
