Buying Land To Build A Home? Here's What You Need To Know About Land Excavation And Site Preparation

Construction & Contractors Blog

If you plan to purchase a parcel of bare land to build your dream home, then it's important you understand the necessary processes of land excavation and home-site preparation.

While it would be ideal to purchase a perfectly flat piece of land and start building immediately without any preparation, this is hardly ever the case. The area where you plan to build your home will need to be professionally prepared to accommodate the structural stability necessary to build a long-lasting home.

While you will need to hire a professional land excavating service to prepare the home-site, it's vital you have a clear understanding of the process. To assist you, here are the basics:

A Geotechnical Report Must be Completed

Before you can do anything to your bare land, first a professional geotechnical report will need to be completed. The report will determine many important aspects of the site, including:

  • soil properties
  • soil stability
  • groundwater locations
  • depth of the freeze/thaw line
  • site drainage

The geotechnical report will be required to obtain the necessary zoning and building permits to ensure you can build your home where you desire.

A Survey Crew will Determine the Lot Boundaries and Home Foundation Locations

Once you have the geotechnical report and building permits, then a survey crew will bring out their transoms and stake the boundary lines and home-site.

Heavy Equipment is Used to Remove Vegetation and Soil

Once the home site has been determined, a land excavation service will come in with heavy equipment and clear the site down to the depth required for the foundation. 

First, trees and vegetation will be removed and taken offsite for disposal. Second, the soil will be removed and stockpiled on-site to use as backfill after the concrete foundation has been poured.

If your parcel of land has very shallow bedrock, then it may be necessary to use explosives to break through it for removal.

The last step is to grade the remaining soil to ensure the site will drain property during storms.

In addition to clearing the site and preparing it for your new home, the area for the driveway and any patios you plan to build can be excavated at the same time to save you some money down the line.

Compaction Equipment is Used to Compact the Soil to Withstand the Weight of the Future Home

After a home-site has been excavated, the remaining soil needs to be compacted with heavy machinery. This will ensure the new home's foundation is stable.

A Foundation Contractor will Pour a Concrete Foundation

When the site has been properly cleared and compacted, then a foundation contractor will come onsite and pour the concrete foundation for the house.

The Land Excavation Contractor will Backfill Around the New Foundation 

Finally, your land excavation contractor will use the stockpiled soil from the excavation process and backfill around the new concrete foundation. Once this has been completed, then the rest of your home can be built by your contractor.

All About Building a Home

Welcome to my website. I'm Albert Frost. Besides my dad, one of my biggest role models was my uncle Rick. He was a construction contractor who would let me come on his construction sites and also taught me everything he knew about building homes, including how to install hardwood flooring and add insulation. I always wanted to grow up to build houses like my uncle. I used to help my uncle with a lot of the grunt work needed to make a home a reality. But then I hurt my back playing football. Until I heal completely, I'm going to devote as much of my time as possible to teaching others about various construction topics I'm interested in.
