Materials Are Used for Trenchless Sewer Replacement

The materials used to repair or replace a sewer line can significantly impact the costs. Plastics like polyvinyl chloride (PVC) and acrylonitrile butadiene styrene (ABS) are the most common because they’re inexpensive, lightweight, and easy to install. Other options include cast iron and copper, which are more expensive but offer superior durability.

How old your existing sewer pipe is also a factor. Older pipes are more likely to have cracks and breaks, while newer pipes are less prone to issues. The length of the sewer line will also impact costs, as it will take longer to dig and replace a shorter line than a longer one.

Whether your property has underground systems like water, gas or electric lines also impacts costs. If you have these lines located in the same area as your sewer line, they will need to be relocated or rerouted during the trenchless sewer replacement process. This can increase your overall cost.

What Materials Are Used for Trenchless Sewer Replacement?

Another important factor is the current condition of your sewer line. If it has significant scale buildup or other mechanical defects, the contractor may need to perform a trenchless cleaning or de-scaling service before the lining can be installed. This can add a day or more to the total repair time.

Trenchless methods are minimally invasive, but the contractor still needs to dig access holes. The number of access holes needed can also influence costs. If the damaged pipe is located under landscaping or a swimming pool, digging can be expensive. But if the line is close to the house, contractors can dig through a small hole in the basement or crawlspace.

Other factors that can affect cost are the type of pipe and how complex the job is. For example, if your sewer line has many bends, the contractor will need to create more access points. This can be more expensive than repairing a straight line.

The trenchless method you choose will also affect the final cost. Pipe bursting and pipe lining both have different material costs and labor rates. Pipe bursting is typically more costly than pipe lining due to the additional machinery involved.

In addition, if your existing sewer line is made of clay, it will be more expensive to install a trenchless sewer replacement than if it was made of PVC or ABS. Clay is a dense and heavy material that’s difficult to work with. It’s also susceptible to root intrusion and chemical degradation.

To help keep your costs down, you can prevent damage to your sewer system by only flushing soluble waste and by regularly having your drains cleaned. If you have a septic tank, make sure to pump it out at least once a year. Additionally, make sure you’re not putting non-soluble waste into your drains, such as sanitary napkins and diaper wipes. Using a quality toilet paper that’s thicker than ordinary brands can also prevent blockages. Also, make sure to have your property cleanouts regularly inspected and cleaned.
