Can the liner be inserted from more than one access point?

Yes. The liner can be inserted through a cleanout or from a small excavation and the end of the liner is open so there is no need to access the other end of the liner.


 

When inserted through a clean-out how is the liner directed either upstream or downstream?

Our patented soft shoe allows us to direct the liner either upstream or downstream.


 

How are side connections in small diameter laterals reinstated without excavating?

By use of an optically guided robotic reinstatement cutter.


 

How does the liner cure?

At ambient temperatures the liner can be cured in 4-6 hours or less. Hot air or steam can hasten the process.


 

How do you cut the ends of the liner open?

There is no cutting required because the bladder extends beyond the end of the liner keeping the end of the liner fully open.


 

How many lateral installations can be performed in a day?

On average 4 to 6 laterals can be renewed in one day.


 

What size pipes can be renewed?

Pipes from 2” to 4” diameter.


 

How many feet of pipe can be renewed by one liner installation?

Up to 130’ of 4” liner or 100’ of 6” liner can be inserted through single installation.


 

Will the liner significantly reduce pipe size?

There is a minimal reduction in diameter, but the smooth bore interior of cured in place pipe typically improves flow rate. Also, pre-cleaning typically removes encrustation that has restricted flow.


 

Are there other pipe repair applications suited for the lining process?

The Liner system is often used to renew roof drains, industrial piping, commercial piping, and residential drain and waste piping.


 

Does the liner stick to the host pipe?

How do you verify the bond between the liner and the host pipe? No manufactured CIPP product or installation contractor can tell you when the liner sticks and how well it is stuck to the pipe. There is grease in sewer pipes which has a serious effect on adhesion. However, wherever the pipe is thoroughly cleaned good adhesion will occur.


 

Is the lateral liner root resistant?

Yes, the lateral liner is a new pipe within a pipe so there are no open joints, cracks or crevices where roots have an opportunity to grow.


 

How long will it last?

The liners have an engineered service of 50 years based on ASTM F1216-09. The service life is based on extrapolation of testing data of the liner’s physical properties.
