Governmental Trenchless CIPP Restoration
With the new Trenchless CIPP Technologies, for governmental pipe restoration, FPS is able to repair all forms of broken, split, or cracked pipes. Our Cured-In-Place Piping System allows us to restore drain lines, sewer lines, stacks, and laterals. This new CIPP pipe has an estimated life expectancy of 50 years. Our CIPP Process is fast and effective. This Trenchless Technology means that we are able to avoid cutting through concrete foundations, digging up landscaping, and excavating paved areas. We offer a superior method of pipe restoration that is usually more cost effective than the old fashioned alternatives.
The lining is typically positioned within a translucent bladder (or connected to a positioning hose) and vacuum impregnated. Next, the liner/bladder assembly is inverted through the cleanout and directed upstream or downstream by use of a guide shoe.
Only the bladder is located within the cleanout since the liner does not begin to invert until it is positioned within the horizontal lateral pipe. The process includes the use of a camera port which allows a lateral push camera to be inserted inside the translucent bladder, providing visual verification of the liner placement prior to curing.
The liner can be cured at ambient temperatures or accelerated with steam. The liner can be installed where the inflation pressure is never compromised; because the liner remains inflated from the time of inversion throughout the curing process. This is an important feature as the pressure used to invert the liner tube may move broken pieces of pipe. If inflation pressure was removed the broken pieces of pipe could fall on the deflated liner. Inflation, deflation and subsequent re-inflation could result in a defective liner which would result in required excavation to repair the defective liner.
When cured, the bladder is re-inverted and removed from the pipe. There is no cutting required in the liner because the liner is started below the test tee and past the side connections. Further, the liner is open ended at the main location so there is no cutting at the upstream end or the downstream end.
