Excavation Methods for Different Purposes

Excavation in layman’s terms, can be described as the installation, repair, and maintenance of gas, sewer, and water lines. These lines are important to protect the safety of occupants within commercial buildings and homes. Plumbing excavation uses various techniques for different purposes.

Excavation Methods for Different Purposes

Here are some of them:

1. External

This is probably one of the most time-consuming excavation methods, but is extremely effective. With the external method, a large part of the property might be dug so workers can reach sewer lines. When water line and sewage pipe repair work is needed, a closed-circuit camera can identify the specific problem and minimize the disruption to the landscape.


2. Rerouting

Unlike the complete external excavation method, this one might require less digging. It can also be less time-consuming and costly. With rerouting (as the name suggests), new sewer lines are rerouted from the outside of the building structure. A special pipe lining is pulled through the already-existing pipework. One the lining is in place, pressure can be applied to it. This is called “cured-in-place piping.” The rerouting method is a form of trenchless repair that is less invasive than some other methods.


3. Interior

This method is mostly suitable for settings where there is a single leak. It is not as damaging as exterior excavation but can still be an extremely invasive method of sewer repair. A jackhammer is used to penetrate the ground and dig a hole to the leak. Should there be more than one leak in the plumbing, external excavation is the likely approach.
