Site grading is a technique used by excavation professionals to adjust the slope of an area prior to building construction. Before a new structure is erected, evening out the surface through grading can provide a stronger, more even foundation.
How is Site Grading Performed?
For both commercial and residential applications, professional engineers may need to weigh in on the site to determine whether it will require grading to achieve a level base. Factors like soil composition and moisture levels will be considered to assess the scope of the project. If site grading is indeed required, an excavation services team will need to be hired to perform the work. They’ll use heavy machinery like bulldozers and excavators to prepare the surface for leveling, then go in with a grader to achieve an even finish.
What is Site Grading Used For?
In addition to leveling out the ground to provide a sturdy foundation for construction sites, grading is also used to direct the flow of runoff water. When sites aren’t properly engineered, it can cause problems to a home or commercial building and its surrounding property. Issues like erosion, foundation damage, and basement flooding can all occur when properties aren’t graded to facilitate proper drainage.
Grading a piece of property so water flows away from buildings usually requires the construction of a slope of at least 5%. This translates to a six-inch drop in height over a 10-foot distance away from the building. While some excavation experts can grade surfaces using less of a slope successfully, this is the general rule of thumb many general contractors follow to ensure effective runoff.
