Traditional trenchless lateral relining utilizes the use of a cleanout which is usually situated somewhere close to the property line. This access point is used for cleaning purposes, for camera access and for actual liner installation in certain cases.
Liqui-Force has designed new systems that allow all of the lateral cleaning and installation to take place from access at the manhole, with no need for a cleanout or hole in the lawns of homes or businesses.
The preparation of the lateral is done through the use of a robot inserted into the mainline sewer, which then travels up the service lateral. This device will remove roots, debris, calcite and other foreign materials and wash out the lateral at the same time. During this process, a video inspection and exacting measurements will take place. These two operations will provide a service quality rating and allow for correct sizing of the liners as well as provide for the changes of size made through transitions.
Following the preparation process, and new installation system will launch a liner from inside the mainline sewer and send it as far as necessary up the lateral. At the same time, this one piece system will connect to the mainline sewer to repair defects at the junction, and stop I/I. This newly constructed liner is designed for a fifty year (minimum) life span.
These two new systems will make “Trenchless” totally “Trenchless for the first time”. Laterals will be rehabilitated much easier, in less time, with further reductions to traffic problems and carbon footprint. The simplified system will minimize long term liability to the customer and contractor, as well as save trees, roads driveways and sidewalks.
