    What You Need to Know About Trenchless Sewer Replacement

    March 3, 2021 By //  by ehretco

    Trenchless sewer replacement has many advantages over traditional sewer excavation. It requires less construction, reduces traffic detours, and reduces disruption to people around the construction zone. It also minimizes disturbance to landscapes and outdoor structures, making it a frequent choice of sewer replacement contractors and homeowners.

    Two common methods of trenchless sewer replacement are sliplining and pipe bursting

    Both methods involve slipping a new pipe into the original pipe. The key difference is whether the old pipe is dismantled or used as an outer shell for the new pipe. In some cases, both methods are ideal choices, but a household plumbing inspection might find one more beneficial to certain situations.

    Sliplining

    Sliplining requires the new pipe to be narrower than the original pipe. The new pipe is pulled or pushed into the original pipe, and then grouted into place. Sliplining doesn’t dismantle the original pipe, which has become an outer shell for the new pipe, so the new pipe can’t be upsized. Upsizing the pipe’s capacity would require dismantling the original pipe, as is done with pipe bursting.

    Pipe bursting

    Pipe bursting is exactly as it sounds. The sewer replacement plumber pulls a bursting tool through the old pipe, forcing it open as the new pipe is dragged into place. Pipe bursting can replace pipes of similar or larger size, typically made of high-density polyethylene (HDPE). It’s also more environmentally-friendly than sliplining, which requires chemicals to grout the new pipe into place.

    Cured-in-Place Pipe (CIPP) Lining is another common method

    CIPP lining is ideal for repairing sewer pipes that don’t need to be upsized or be entirely replaced. It creates a new lining within the old pipe. A resin-saturated felt tube is inserted into the old pipe and turned inside-out with air or water pressure. This puts the resin in contact with the old pipe so it can be cured and hardened into a new lining. 

    Trenchless sewer replacement can’t fix pipe bellies

    Despite the benefits of trenchless sewer replacement, sewer lines that sag due to shifting soil and improper bedding can’t be replaced with trenchless methods. This is because a new pipe can’t be led through a misshapen pipe. Sewer replacement contractors also won’t cure a new lining into a pipe belly, as solid waste could remain stagnant in the belly and form a clog. The only option is to dig out the entire pipe.

    What are the Benefits of Trenchless Sewer Replacement?

    January 5, 2021 By //  by ehretco

    Decades ago, the only way to replace a sewer line was to entirely remove its damaged pipes. Workers had to upend all surrounding landscape and structures to access the line, making for long days or weeks of excavation. Now, modern technology allows an easier, quicker, and less-expensive method to replace damaged sewer lines: trenchless sewer replacement.

    Minimally Invasive

    Traditional sewer replacement is messy. If the damaged segment of a sewer line runs beneath a garden, fence, or building structures, they’ll all be dismantled or unearthed for the excavation site. Workers will dig trenches to access the entirety of the damaged sewer pipe, which is avoided with trenchless sewer replacement.

    Instead of exposing the entire sewer pipe, trenchless sewer replacement creates entry points for new piping to be fed through. There are typically two entry points, so instead of digging up the entire pipe, workers only have to dig up enough land to access those portions. This leaves the rest of the landscape untouched.

    Higher Quality & Functionality

    Trenchless sewer replacement can improve your sewer line’s functionality by installing higher quality pipe liners or pipe replacements. A new pipe liner can reinforce your sewer line by increasing flow capacity with stronger piping material, and a seamless pipe replacement can prevent off-set piping caused by tree roots and other environmental factors. Not only is your sewer line repaired, it’s upgraded with the latest pipe technology. Your sewer line will last longer  and have fewer needs for residential plumbing services.

    Saves You Time & Money

    Smaller excavation sites means shorter project times. There is less land to dig, and less land to replace after the pipe is repaired. This frees up substantial time for the actual replacement. Workers can be in and out of site within a day, compared to the multiple days often required by traditional sewer replacement. And if your sewer pipe damage extends beyond your property and underneath the sidewalk, traditional replacement might stretch into a week or longer.

    Trenchless sewer replacement also can cut down the money you’d spend with traditional replacement. You won’t need to pay for dismantling all the structures that would get in the way of a complete excavation. You’ll also have a lower bill to pay for post-project cleanup, including replanting the small sections of your lawn and garden that were dug up. Make sure you plant greenery that is pipe-friendly and won’t grow into your sewer line, or plant them far away from your pipes.
