Link-Pipe Insta-Liner™ forms a composite structure with the damaged, or eroded host pipe and creates a new pipe even where the old pipe is missing. The new composite pipe combines the strength of the new liner with sections and pieces of the host pipe, all bonded together with a cementitious grout.
Link-Pipe Insta-Liner™ can be ordered with a 50-year, 100-year, or any custom designed service life. In all cases, a 10-Year Manufacturer Limited Warranty applies for all materials.
Application
Link-Pipe Insta-Liner™ is made up of short links of stainless steel sleeves, which are coupled together to create a continuous liner of a specified length. Individual links are coupled together and are pulled through the host pipe by a cable from the opening at the far end of the host pipe. A continuous stainless steel liner is thus formed.
A specially formulated cement grout is then pumped to fill the annular space between the host pipe and the Insta-Liner™.The grout flows into all cracks and joints, joining together the Insta-Liner™ and all old pipe sections into a solid and unified structure.The SST-316 Insta-Liner™ is selected for the purpose of providing a repair that lasts at least 100 years in a city culvert, sanitary and storm sewer environment.

Link-Pipe Insta-Liner™ has the following specific benefits:
- Technical staff offers a one-day training seminar from Link-Pipe Inc.
- Just three persons can do the job. Additional labor would increase the productivity.
- The equipment needed is very simple and readily available.
- A winch with ¼-inch cable and capacity to pull with a force equal to half the weight of the SST core of the Insta-Liner™.
- A grout pump available from many tool rentals and also Link-Pipe Inc.,
- 1-¼-inch Grout hoses of required length,
- Set-up involves coupling the links and passing them into the host pipe. The coupled segments are pulled through the host pipe, forming a new liner. A 30-meter (100-ft.) length culvert can be re-lined in less than one hour.
- The liner is also suitable for short repairs. Coupled with expandable Spot Repair Sleeves, e.g. GROUTING-SLEEVE™. This lowers the cost of short repairs by avoiding pipe sections that need no repair.
- CCTV for inspection before and after work
- Vac-Truck for cleaning before re-lining
The new pipe has the strength of the original sound host pipe and much more. Under 10-psi grouting pressure, the annular space and all host pipe cracks are filled by the cement grout. The LINKcRETE Grout has enhanced adhesion properties, due to Link-Pipe proprietary additives. The cracked or corroded host pipe pieces are bonded together. Furthermore, should there be any cavities in the soil around the host pipe, the grout flows out to fill all accessible spaces. The end result is a very strong and sound new pipe.
