Aqualiner involves inserting a glass fiber reinforced polypropylene sock into a
deteriorated pipe. Once the composite sock has been inserted into the host pipe, a
silicone rubber inflation tube pushes a heated pig through the composite melting
the thermoplastic sock against the pipe. The inversion bag presses the molten
thermoplastic composite sock against the pipe wall where it cools to form a solid
glass reinforced thermoplastic liner.
• No mixing of chemicals – long shelf life
• Environmentally safe – no releases
• Structural – capable of withstanding internal and external pressure
• Thin liner – minimizes any loss of capacity with a liner
• Trenchless method of installation- minimizes excavation and disruptions
• Still in incubation – not commercially released yet
Main Limitations
Cited
• NSF 61 listing and UK approvals in process (DWI Regulation 31).
