Home Excavation Techniques Meant for Deep Foundation Construction

New construction projects, archeology, and even soil removal projects often require excavation.  Based on your needs, there are several excavation techniques that you can choose for your project. Hiring the best excavation contractor is therefore very important to ensure that these projects are completed correctly and safely for reliable future use.

Whether you are undertaking a commercial construction or building a new residential home, you need to have the site cut for deep foundation construction. This is true, especially if you want your construction to remain strong for several years. Here are some of the best home exaction techniques meant for deep foundation construction.

Vertical Excavation

This is perhaps the most common deep foundation construction excavation method. This type of excavation is mostly used in large urban areas where many layers of the ground need to be exposed. Large buildings such as skyscrapers and dams require this technique to ensure that they remain stable.

Vertical excavation is also used in wet or loose soils where the banks must be supported by sheathing and shoring. It involves excavating a significant depth of deposits until all the wet and loose soil is removed. Vertical excavation is one of the most preferred methods by residential earthmoving contractors.

Rock Excavation                                                                    

When a technique is classified as rock excavation, it implies that the materials consist of sedimentary, igneous and metamorphic rocks that need to be removed. These materials could be in the form of boulders, solid rocks or even detached stones.

These materials are normally removed through blasting, by the power of shovel or by using any other power equipment that can provide the same results. Specific criteria need to be used to ensure that these materials are excavated well.

Island Excavation Method

In this method of excavation, the centre of the area is dug and the material is placed next to the retaining wall to provide a slope. After that, the major part of the building will be constructed at the centre. Next, the slope soil will be removed and the struts will be put between the main building and retaining wall.

Once everything is done, the strut will be removed and the remaining parts will be constructed. Sometimes this excavation technique may require the use of a brace or anchored technique to remove the slope soil material, especially when the excavation is very deep.


Although there are other types of excavation for deep foundation construction, these are the main strategies used by the earthmoving contractor.  Therefore, it is vital to look for an experienced contractor to get the job done on time and budget.
