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-PIPE™.

 Patents

The first patent of Link-Pipe spot repair sleeve was registered in the United States by Maimets 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.
