Top Construction Excavation Techniques

When you are working on the construction of a building, the composition of soil is important. You have to keep track of loose soil, inclines and other issues that may lead to flaws in the structural integrity of the building. This means that you may need to excavate the site before you start the build. This way, you know that the ground is level.

Excavation involves cutting and filling. Here are a few of the common excavation methods.

Vacuum Excavation

While most techniques involve cutting into the earth, this method does not. Instead, it uses suction to remove soil and debris. This is safe because without the cutting element, you aren’t at risk of hitting utility lines.


Benching takes out the need for structural supports. Essentially, professionals cut benches into the face of the site. When your soil is stable, this is a great technique.

Vertical Excavation

This is the most common form of excavation. Essentially, you dig down into the Earth about 15 feet. This is important when you have limited space and site access. When performing this type of excavation, slope the walls at an angle to avoid a cave-in.

Horizontal Excavation

For the most part, if your site is smaller, then you may be able to use this method. Professionals can complete this excavation with a pickaxe or a spade.

Hybrid Excavation

Hybrid excavation is what its name implies. Larger sites may require professionals to use a mix of horizontal and vertical excavation.


As you dig deep into the Earth, you run the risk of hitting the water table. Cofferdams will temporarily stop water from infiltrating your site by creating a barrier.

When it comes to construction, excavation is important. It is the first step to proper construction builds and guarantees that your building will be more structurally sound. Of course, as with any construction site, the proper equipment and safety techniques should come first. For more information on techniques and safety, call D2 Site Work at 301-800-7883.
