A Guide to Ground Grading in Construction

What Is Grading in Construction?

Grading, or land grading, refers to the process of adjusting the slope and elevation of the ground to create a stable base with proper elevations and slopes for construction projects. This is done using heavy machinery like bulldozers, wheel tractor-scrapers and graders to move soil. The site grading process follows a grading plan that is based on existing site conditions and the land requirements for a build. The goal of a thoughtful grading plan is to stabilize the ground, create proper surface drainage, avoid erosion, improve the aesthetics of a project and ready a site for building foundations and other improvements. Sites with existing buildings benefit from a regrading plan when there are drainage issues or new additions being constructed.

Grading also includes leveling to smooth the surface for uniformity and stability and refine the gradient per design specifications. Well-executed grading and leveling prevent serious problems like uneven foundation settling, stormwater accumulation and water drainage.

The Difference Between Grading and Excavation

Both excavation and grading are early-phase construction processes that support a site’s structural integrity. Land excavation is one of the first steps on a construction site and involves digging and removing materials such as soil and rock to prepare the site for structures and utilities. Grading reshapes the contours and elevation of the land to support the design of the site and structures. This cut-and-fill work creates the necessary surface for a specific build. 

Types of Grading in Construction

There are several types of construction grading services. Depending on the project, multiple grading techniques may be used to level and slope the land. Types of grading in construction include:

Rough Grading

This is typically the first stage of grading. During rough grading in construction, major cut-and-fill operations are performed to shape the terrain according to the construction and grading plan, and to remove debris and vegetation that weren’t removed during excavation. This step sets the basic contour for more detailed work.

Fine Grading

This technique is more precise than rough grading. Fine grading brings the earth to exact elevations and specifications for each area’s use. The team performs detailed work and ensures all areas are properly compacted and sloped. This is when the site preparation team ensures that the land meets all final design grades and specifications for drainage, stability, and surface preparation. It’s often followed by the installation of topsoil, sod, landscape and pavement.

Landscape Focused Grading

Landscape focused grading services enhance the visual appeal and functionality of outdoor areas and prepare a site for landscaping projects. This involves shaping the land to create or remove elevations, control erosion, support plant life and improve drainage. 

A Level Site Matters

Grading that isn’t precisely completed can lead to costly repairs and even make a site unbuildable. After properly grading the land to design elevations, contractors have peace of mind knowing that water will drain away from streets and structures, and that the land is solid. Without effective ground grading, water pools in the wrong places, structures may become unstable, and landscaping may be damaged long-term.
