NOKAOI
Pipe & Restoration, LLC

What We Do...

NOKAOI Pipe & Restoration specializes in the restoration of drainage and water supply pipelines to near original flow efficiencies, after suffering from years of corrosion, scale, build-up, pin-holes, root invasion and subsequent structural damage.

All pipe, no matter what they are composed of (wood, clay, concrete, lead, cast-iron, asbestos, ductile iron, PVC or ABS), deteriorate or lose their ability to efficiently convey water/waste as they age.  They will all suffer from some form of breakdown due to leakage or flow stoppage as a result of rot, breakage, corrosion, clogging, root infestation or chemical build-up.

Every residence, business and government institution relies on its potable water and sanitary drainage lines for a quality lifestyle.  NOKAOI Pipe & Restoration is here to help restore and maintain that quality of life for all in Hawai'i.  With our state-of-the-art equipment and technology, our services can save you hundreds and even thousands of dollars over traditional plumbing and pipe repair, and in most cases, WITHOUT DIGGING & EXCAVATION!

Save time and money with NOKAOI's trenchless C.I.P.P. (Cure-in-place-pipe) system.

​We can service damaged pipelines in diameters from 2″ to 8″ in less than a day and in most cases less than 3 hours!  NOKAOI Pipe & Restoration is the only company on Kaua'i utilizing a "trenchless" C.I.P.P. system.  ​​The pipe restoration process using Perma-Liner provides an alternative to re-piping by using in place pipe restoration which means no digging or excavation and doesn’t destroy walls, floors, ceilings or foundations.

The C.I.P.P. Process

A resin-saturated felt tube made of polyester, fiberglass cloth or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe.  It is usually done from the upstream access point (manhole or excavation).  Little to no digging is involved in this trenchless process, making for a potentially more cost-effective and less disruptive method than traditional "dig and replace" pipe repair methods.

TELEVISE THE PIPELINE
Pipeline is inspected with camera to find the problem.
Picture
CLEAN THE PIPELINE
Pipeline must then be cleaned out to remove roots, dirt, debris and any potential objects that could disrupt lining.
Picture
​TAKE MEASUREMENTS
Measurements of the pipelines diameter, depth and length are taken. The liner and calibration tube is then cut on the job site according to acquired measurements.
Picture
​MIX & MEASURE RESIN
Resin is also measured and mixed according to the acquired measurements
Picture
​POUR INTO LINER
The resin is then poured into the liner and rolled or " wet out" many times to ensure complete impregnation of resin to liner.
Picture
​LOAD INTO INVERTER
Impregnated liner and calibration tube is then loaded into the inverter
Picture
​INSERT INTO EXISTING PIPELINE
The liner is then inserted into the existing pipe using directional hoses and inversion heads. These ensure proper insertion.
Picture
​INVERT WITH AIR PRESSURE
Air pressure then inverts inside out allowing resin to bond and seal with existing host pipe. The calibration tube acts as a ballon to keep the liner in place as it cures.
Picture
​READY FOR SERVICE
Once cured, the calibration tube is removed and the pipe is ready for service.
