Sewer Repair 101: Types of Excavation

While most sewer problems like leaks and cracks can be quickly fixed with “no-dig” trenchless methods, there are times when severe issues like a collapsed pipe make excavation necessary. While this type of sewer repair in Saline, MI, can be invasive, rest assured that we at Dynamic Drains will do our best to keep disruptions to a minimum and deliver a hassle-free process.

To help you make informed decisions, we list the different types of sewer excavation below.

Exterior Excavation

Exterior excavation, also referred to as open-top excavation, is the oldest sewer line replacement method. It involves digging out the entire sewer pipe for assessment and restoration.

The first step involves mapping out all the utility lines to ensure we don’t damage them. Our technicians then excavate the sewer line to replace the damaged part.

We often recommend this method if basic sewer pipe line repair isn’t enough, if the damage is in a hard-to-reach area, and if the utility lines are too close to the affected pipe. This method can take days to finish because of extensive digging.

Interior Access Excavation

Meanwhile, interior access excavation involves digging a hole toward the leak before we perform sewer line repair. In most cases, we may need to replace the flooring because we need to penetrate layers of concrete and gravel.

This works best when there is only one leak. That is because this method can be invasive if there are multiple leaks, as we need to jackhammer several holes. In that case, exterior excavation presents a more cost-effective solution to repair or replace sewer line.

Excavation is a complicated task that requires the right skills and equipment. This is where the pros at Dynamic Drains fit the bill.
