The Advantage of Trenchless Sewer Line Repair
A broken sewer line doesn’t have to mean tearing up your yard. Our team of trenchless engineers uses the latest technology to replace sewer pipes, sewer lines, and sewer laterals without digging up your property. As an industry leader, PIPE SPY Marin was the first plumbing company in the Bay Area to use trenchless sewer repair and trenchless sewer replacement. Since 1998, we have developed a reliable process that allows us to work quickly with minimal damage to your landscape. Our list of satisfied customers continues to grow.
​
PIPE SPY Marin has been Diamond Certified since 2012, and is the only Diamond Certified sewer contractor in Marin County. We are an approved sewer contractor for all the sanitary districts in Marin County. We will keep your trenchless sewer repair cost down.
Be Sure to Get a Sewer Camera Inspection
If a sewer camera inspection has confirmed the majority of your sewer lateral is in good working order, but has a spot that causes a backup, a spot repair may be right for you. A repair to a broken sewer line, offset pipe joint or short section of root intruded pipe, can extend the working life of your sewer. PIPE SPY Marin will recommend spot sewer repairs when it's the right choice to help you manage your sewer line.
​
Exterior clean outs provide access to the building sewer lateral for servicing the sewer pipe with cleaning equipment, inspection equipment, and provide an exterior backup relief point. This relief point can prevent sewage from backing up into your home's interior.
Trenchless Sewer Lateral Replacement
The trenchless sewer lateral replacement process reduces the cost of replacing a sewer pipe and installs a better product in the ground than the traditional open cut or trenching procedures.
​
Though this process generally eliminates the need for digging long and deep trenches, it does require strategic access points and holes, to use the existing sewer lateral’s position in the ground as a guide for the new replacement pipe. This eliminates disturbing large areas of your property’s hardscape and landscape.
What Are the Benefits of Trenchless Sewer Line Repair?
The less your surface is disturbed, the more you save. You can get back to enjoying your yard or garden right away – instead of days later.
​
Before TRIC TOOLS made this process accessible to your property’s side and rear yards, it cost tens of thousands of dollars and days to carve a trench from your house to the sanitary main.
​
Trenchless replacement saves you more than money. PIPE SPY Marin can replace or repair your sewer lateral in one day. Our respect for your house, landscape, and neighbor’s property will leave you feeling we were never there, but you will have a new trouble free sewer. There is minimal impact on your garden, irrigation systems, pathways, and stepping stones. There is little interruption to your lifestyle and you do not have piles of enriched soil around for days.
Can I Use Trenchless Sewer Line Repair For My Project?
Yes, most existing sewer laterals can be replaced with trenchless replacement technology.
​
Most PIPE SPY Marin customers are trenchless sewer replacement or trenchless sewer repair customers. Digging a long trench is almost never needed, because of the flexibility of trenchless sewer technology and the exactitude of our sewer diagnostics.
​
The slope of an old sewer might have a "negative grade," meaning that the pipe sags or does not have a proper down-sloping angle per local plumbing requirements. Negative grade areas do need to be trenched, to first correct the pipe slope. Even if a sewer pipe has a negative grade, PIPE SPY Marin can use a combination of trenchless and open cut. The solutions used for your sewer line repair project will depend on how and where your original sewer was installed, how it may have been repaired in the past, and what kind of damage it has experienced.
Risks and Limitations
Trenchless replacement technology is not idiot proof. It takes awareness and skill to apply the tools, and intense power to pull pipe underground.
​
Plumbing branch lines connected to the sewer lateral must be accurately located, exposed, and reconnected to the sewer lateral. Often other house utilities, water, gas, and electrical lines, are exposed at excavation points and care must be used to not damage them. There are some situations where the lines may need to be cut or relocated.
​
A person cannot know what is underground until it is dug up. A sewer pipe surrounded with concrete will stop the pipe from bursting. Concrete will not allow the bullet to expand the tunnel and make room for the new pipe. There must be awareness of retaining wall footings, multiple layers of the road, and other obstruction potentials.

Trenchless Slip Lining
Cured In Place Pipe (CIPP) is a trenchless rehabilitation technique that installs an epoxy saturated fabric lining in your existing sewer lateral.
​
Though approved for use in Los Angeles and Sacramento areas, trenchless slip-lining technology is generally not approved by Bay Area sanitary district authorities. This process does not fix offset pipe joints or breaks in the pipeline. As a liner, the inside diameter is reduced, and therefore the life expectancy of a lined sewer pipe is not as good as a new sewer pipe with a full 4” inside bore.
​
Pipe Spy can advise you if slip lining is an appropriate solution for your situation. We'll always recommend what's best for the long-term integrity of your sanitary lines.
