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

Link-Pipe Inc. provides rehabilitation system for repair of Round, Horse-shoe and Box culverts.

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.

Gas Main Products

Link-Pipe Inc. has available Gas Sealer™ Sleeves to seal cast iron and low pressure mains.

Gas Sealer™ Sleeve was jointly developed by Link-Pipe Inc. with Consolidated Edison, KeySpan Energy (prev. Brooklyn Union/Lilco) and NYGAS.

Pressure Pipe Products

The pressure seal is one of our no dig sewer line repair solutions that can be used for sealing pump mandrels, siphons, pipes subjected to internal pressure, and for sealing exfiltration.

It is designed for spot repair in sealing joints, transfers cracks and holes. We designed our Pressure Seal™ to seal pressure pipe with ultimate pressure up to 150 psi. (10 bar). For higher pressures, Link-Pipe can accomodate and design according to your needs and the pipe's condition.

Standard Link-Pipe's Pressure Seal™ is made of stainless steel expandable cover covered with sealing material. Sleeves are equipped with Ratchet Locking mechanism to accomodate dimensional tolerances of the host pipe up to +/- 1/2".  Pressure Seal™ is designed for sealing pressure pipes and it is uniquely suitable for old cast iron mains that have unpredictable variations in manufacturing tolerances, -roundness and -joint offsets to which the sleeve will conform.

Water Well Products

The Link-Pipe internal repair sleeves are designed for rehabilitation of well casings and screens, repairs holes, cracks and corrosion damage.

The corrosion of well casings or screens can cause holes to develop in a casing and cause the screen slot size to increase, allowing sand, fines and gravel pack to enter the well. Link-Pipe can help repair this.

  • Extends service life of the well
  • Reduces pump equipment cost

  • Minimum diameter loss in the well casing
  • Complete control in locating the repair
  • Repair sleeves fit a wide range of well casing diameters
  • Repair Sleeves can be customized for a different chemical environments

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.
