Trenchless Sewer Repair - Why Dig If You Don't Have To?
Advances in technology in the sewer repair industry means faster, easier, and more economical sewer repair and replacement for homeowners and business owners alike.

Trenchless Sewer Repair means just as the name implies. You can have any length or diameter of underground damage sewer lines replaced or repaired without digging a big trench across your property, and without the need to disturb structures like garages, porches, and driveways. Why would you ever even consider allowing a contractor to dig up your yard now that you know you don't have to?

Methods Of Trenchless Sewer Repair


 

SEWER PIPE RELINING - This is the preferred method of trenchless sewer line replacement as in most cases it requires no digging at all and is commonly referred to as “No Dig” sewer pipe repair. This method involves relining the entire length of sewer pipe with seamless, flexible PVC infused liner that is coated with epoxy resin. The new liner is unraveled and blown into the old sewer line using air usually from an existing access point called a clean-out. The epoxy coated side is simultaneously pushed against the interior wall of the existing sewer line. Once in place, a bladder is inserted the full length of the new liner and inflated with high pressure, heated air sealing it to the old sewer line. This effectively seals all leaks, cracks, and voids and leaves a smooth, rock hard seamless new pipe that’s water tight and highly resistant to future root intrusion, a leading cause of failed sewer lines.

SEWER PIPE BURSTING - This method of trenchless sewer repair is usually the second option if sewer pipe relining cannot be performed due to the old sewer pipe being too severely crushed or damaged. With this trenchless sewer repair method, two very small access holes are dug at each end of the sewer line. A cable is run through the entire length of sewer line and attached to a cone shaped tool called a bursting head that is attached to a brand new length of sewer pipe. Using a power hydraulic winch, the bursting head is pulled through breaking up the old pipe while pulling the new pipe in behind it. Sewer Pipe Bursting can easily be performed on a standard 3”-6” residential sewer line and can also be used on large commercial sewer lines up to 56” in a diameter.
