About Us

,

Link-Pipe Inc. develops No-Dig repair products to extend the service life of city sewers to full originally intended use.

LINK-PIPE Inc. continues to develop reliable and innovative technologies for repair of underground infrastructure systems including industrial, steam and gas supply applications.

Link-Pipe Inc. offers only products designed according to modern engineering and material sciences.

History

After 20 years working as a municipal engineer, Lembit Maimets founded LINK-PIPE Inc. in 1980.

By 1980 re-lining method of pipe repair was already widely used. By that time it had already become known that most un-reinforced sewer pipes were only locally damaged except those that were chemically eroded. Maimets had found that the damage in most un-reinforced pipes did not exceed 6% of the pipe length if the sample exceeded 1-mile (1.5km).

By re-lining pipe most of which was perfectly preserved was costly and overloaded the budgets. By repairing only those parts of pipe that were damaged Maimets estimated that more than 50% of money could be saved and used elsewhere where it was more useful. Based on this observation, Maimets designed the first Spot Repair sleeve and called it LINK-PIPEâ„¢.

Patents

Maimets registered the first patent of Link-Pipe spot repair sleeve in the United States in 1978 and sales began in 1980. This event established Link-Pipe as the first commercially available spot repair technology in the world.

Subsequent patents have been obtained for the repair sleeves known as SNAP-LOCK (October 31, 1988), followed by GROUTING SLEEVE, GasSealer, etc.
By the end of 2002, 42 patents have been issued or applied for by Maimets and licensed to Link-Pipe Inc. or its affiliated companies.

Quality Policy

Link-Pipe Inc. is committed to serve it's customers and meet their needs and expectations in the design, manufacture and supply of reliable and innovative technologies and products for repair of underground infrastructure systems using modern management, engineering and material sciences.Link-Pipe Inc. is committed to continuing improvement of its products and services to achieve increased customer satisfaction as well as to ensure compliance with the requirements of the Quality Management System and it's continuing improvement.

As Link-Pipe is dedicated to deliver to the public quality products, it was felt that the quality control in the design and manufacturing of those products should undergo some independent and impartial third party scrutiny. Therefore an application was made seeking certification from International Standards Organization, ISO.

Through ISO certification Link-Pipe has submitted all its design, manufacturing and customer feedback processes to an independent scrutiny by an ISO appointed review agency, ITS.

Applications

Link-Pipe pipe repair system involves covering the damaged area with an internally applied prefabricated stainless steel sleeve. Since these repair sleeves can be installed through an Access Chamber (Manhole) no excavation is needed.

The sleeves are used to repair structurally damaged pipes. They can also be used to restore missing pipe sections without excavation. Infiltration and ex-filtration sealing is made recreating a sound and long lasting pipe.

Not counting the set-up time, an individual repair takes approximately 20 minutes with a crew of two. From one set-up 25 repairs have been made in a 5 hour work period.

Link-Pipe stainless steel sewer repair sleeves are designed for a 100 year minimum service life and carry a 10 year Limited Warranty when used in storm and sanitary sewer environment (Manufacturer specifications apply).

Main areas of application includes:

  • Sewers
  • Water Mains
  • Collector Mains
  • Gas Mains
  • Culverts
  • Pressure Pipes
  • Industrial Pipes
  • Drains
  • Wells
  • Insta-Liner

Sewer Repair Systems

,

Link-Pipe offers Municipalities a new economic way to provide an improved level of service when maintaining their sewer systems.

The savings offered are based on switching from replacement and re-lining of the entire pipe to repair of only the damage by Spot Repair. For this Link-Pipe offers factory made high quality stainless steel and PVC sleeves.

The sleeves are easy to install, need very little equipment.

An analysis of inspection data has shown that of all sewers examined, only 6% on the average were found to be damaged in a typical 1-mile long sample. This translates into only six feet out of every one hundred feet of un-reinforced sewer pipe.

Next to digging, the popular technology for sewer rehabilitation has been relining. This has meant that for every one hundred feet of liner at least 94 feet of sound pipe has been relined where only six feet really needed repair.

If during routine inspection damaged pipe is discovered it takes around twenty minutes to have it repaired if Link-Pipe GROUTING SLEEVEâ„¢, or SewerSealerâ„¢ in shipping cartons are kept on the CCTV truck. Link-Pipe Inc. can supply highly reliable products, installation staff training and trouble shooting assistance for those first time difficult jobs.
