MANHOLE TO MANHOLE REHABILITATION LINING

Now you can reline pipe in tight spaces and areas with low clearance.

TRY TEK’s CWP Inversion Unit is a lightweight, mobile unit that can operate under bridges, power lines, and other places not accessible to traditional water inversion units that require high caffolds or lift trucks. The small footprint allows access to backyards, tunnels, alleys and more!

  • Water inversion limits ground water from entering pipe during the manhole rehabilition pipe relining process because the entire CIPP liner is filled with pressurized water.
  • Water inversion reduces lifts and soft spots and gives the operator greater control and maneuverability around bends and turns compared to air inversion.
  • With water inversion, the liner remains constantly inflated from inversion through curing, which reduces host-pipe damage and cave-ins caused by multiple inflations.
  • Water inversion provides a consistent heat source to allow the CIPP pipe relining material to cure completely and reliably.

The advantages of the water inversion method over the air and steam method.

Runs in excess of 1000 feet.
Invert 1.5 times farther than continuous-feed air units and up to 7 times farther than drum-style units.

Navigate bends and irregularities in the host pipe.
Incompressible water reacts instantly when unit is “jogged,” resulting in easier navigation of bends and irregularities in the host pipe

Complete cures with reliable results.
Because TRY TEK’s CWP Inversion Unit uses a pump, globe valve and head pressure gauge to precisely set water pressure, inversion speed is more controlled and regulated. Water provides complete, consistent curing due to its heat retention properties. And, groundwater infiltration into host pipe is much less likely to prematurely cool liner which can cause incomplete curing.

Water Inversion does not cause blistering and burning of the liner while curing.
Using hot-water for curing eliminates working with hazardous high-temperature steam. Liner coatings are safe from melting or blistering common to high-temperature steam curing.

Water Inversion provides more protection to the host pipe during the relining process.
Liner remains constantly inflated from inversion through curing, eliminating host-pipe damage and cave-ins caused by multiple inflations.
