What is trenchless sewer and drain lining?
In the most basic terms, trenchless sewer lining is the process of creating a new pipe inside the existing host pipe. A resin-saturated felt tube made of polyester is inverted or pulled into a damaged pipe. Little to no digging is involved in this trenchless drain lining process, making for a more environmentally friendly method than traditional “dig and replace” sewer and drain pipe repair methods. Trenchless sewer and drain rehabilitation methods are generally more cost-effective than traditional exhume (dig) and replace methods. Many people in San Diego are now looking to trenchless lining as an alternative to traditional sewer and drain repair.
How do I know if sewer lining is the right fix for my problem?
If you’re having a drain problem the only thing you know for sure is that you need it fixed. The first course of action is going to be to resolve the immediate problem by clearing the line. Once the line is cleared we will conduct a full video inspection of you main sewer and drain lines so we can tell where the problem is stemming from. If the host pipe is deteriorating or your experiencing root intrusion, trenchless lining may be the best option. We also offer sewer and drain line replacement so you can trust that we will show you all the options and let you determine what the best solution is for you.
The process – step by step
- Existing host pipeline is cleaned out with rooter machine.
- Video pipe camera confirms if pipe can receive lining.
- One (1) small pot hole 4ft. x 3ft. is excavated to expose pipe.
- One piece felt liner is treated with epoxy resin.
- Lining is inserted into old pipe, calibration tube is inflated & expands the lining
- Lining is “Cured-in-Place” as epoxy resin cooks and hardens.
- Calibration tube is deflated and removed, video camera inspects the results.
- Pipe lining is a permanent, stand-alone, new pipe line.
- Reline 4″ to 6″ Transitions
- Non-Woven / No Stretch Liner
- Minimum Design Life 50 Years (ASTM)
