DrainLinerTM
can:
1. Restore cracked pipe
2. Keep the host pipe sealed against infiltration
3. Close holes in pipe walls
4. Isolate root intrusion
5. Prevent exfiltration.
DrainLiner
uses PVC-coated polyester needlefelt tube filled with
liquid resin. The impregnated felt hose is inverted from a
Drum by well proven inversion method using compressed air.
The resin filled felt hose is pressed tightly host pipe and
held until cured. The end is a solid smooth pipe that acts
compositely with the host pipe.
The
DrainLiner technology is a low-cost relining method for
the rehabilitation of lateral connections from buildings to
main pipes. This variable ambient cure system has an
adjustable pot life of 20 to 90 minutes, which enables
control of the full curing process to be completed from 1 to 2 hours.
Curing time
can be substantially reduced through applying hot water or
hot air.
