The development of trenchless sewer line replacement over the last two decades was in response to the need for a non-invasive method of repairing underground infrastructure. This option is ideal for many repair situations as it saves time, labor and money.
Here’s how the newer, no-dig technology compares to traditional methods for underground pipe repair.
Traditional Repair vs. Trenchless Repair
Traditional repair methods for underground pipe systems involves creating trenches to reach the pipe of interest. Not only does this digging process damage the landscape above, it comes with a hefty price for the labour and construction involved. Tearing up a lawn, driveway or other urban surface also requires permits and traffic rerouting.
Trenchless sewer line replacement is a relatively new option that eliminates many of the issues associated with traditional repair methods. There are two main types of trenchless sewer pipe replacement: pipe lining and pipe bursting.
Pipe Lining – In this method, a flexible tube is blown into or pulled through the damaged pipe. This tube is coated with a resin, which hardens to create a new, corrosion-resistant pipe inside the old pipe.
Pipe Bursting – As the name suggests, pipe bursting involves breaking apart the old, damaged pipe in the replacement process. A cone-shaped head attached to a steel cable is pulled through the old pipeline, breaking apart the old pipe as it’s pulled along, while also pulling a new pipe into place.
Savings from Trenchless Replacement
The initial cost of installing trenchless sewer lines is higher than that of traditional trenching repairs, but trenchless sewer line replacement will save money in the long-term if repairs are required. The costs of performing no-dig repairs will remain low and consistent, while the costs of traditional pipe repairs can vary widely depending on where the pipe is located and what lies above it.
