For Structural Repair with No Infiltration. Pipe Ø 6 inch-54 inch. If during routine inspection damaged pipe is discovered, it can take as little as 20 minutes for an experienced installer to have the damaged sewer repaired using Link-Pipe GROUTING SLEEVE.
It greatly speeds up the repair process if a few boxes of sleeves are stored on the CCTV truck.
CCTV, a small compressor and 2 to 3 men can complete such an emergency repair.
The Use of Grouting Sleeve
is structurally designed to carry 5psi. (33kPa) external hydraulic pressure with a minimum Factor of Safety of 2.5. The design follows AWWA M11 standard for Flexible Tunnel Liners.
Stainless steel core provides the sleeve with the essential strength needed to support a damaged pipe.
WRc assessed the performance, the strength and effectiveness of the Link-Pipe GROUTING SLEEVE™sewer repair system by conducting loading tests on soil-embedded sleeves.
Structural Core: The material is SST-316 or a higher alloy for domestic sewers. For salt water pipes and tropical climate, higher stainless steel alloys are recommended.
The Stainless steel used meets ASTM Testing standards A267 & A240.
Grout: The Grout is tested and meets ASTM D-1010, D-1638, D-3574, D-412 & D-1042 standards.
The Grout expands and penetrates through the cracks into backfill, and the SLEEVE creates a complete restoration of the damaged pipe lasting at least 100 years.
