Exterior Surface Preparation Description

Proper surface preparation is the foundation of any lasting outdoor project. At CNG Contracting, we handle Exterior Surface Prepping for patios, landscaping areas, shed bases, outdoor furniture setups, and event spaces—ensuring everything starts on solid, level ground.

Our process begins with assessing the area to identify uneven surfaces, debris, or drainage issues that could affect your project’s results. We then clear vegetation, grade the soil, and compact the base material as needed to create a clean, stable surface ready for installation. We use the right tools for each project—whether it’s a stone patio foundation or a storage shed base. Once the prep is complete, the site is smooth and ready for the next stage—no loose soil, no wasted effort, and no surprises later.

Frequently Asked Questions

Do you remove the sod/grass?

Yes. For any hardscape or structure base, we excavate the organic layer (grass and topsoil) down to the subsoil to ensure a solid, non-shifting foundation.

What material do you use for the base?

Depending on the project, we typically use "HPB" (High Performance Bedding) or Granular A gravel, which effectively locks together when compacted to support heavy loads like hot tubs or sheds.

Can you level a very sloped backyard?

We can perform "cut and fill" grading to create flat usable terraces or install retaining walls to manage significant slopes safely.

Area to Cover

Why is a Technical Visit necessary?

You cannot build on top of organics or uncompacted soil. If a shed or patio is placed directly on top of grass or soft dirt, it will settle unevenly within months, causing doors to jam or stones to crack. Furthermore, changing the grade of your yard can inadvertently direct rainwater toward your basement. Our Exterior Surface Prepping assessment evaluates the soil type (clay vs. sandy) and the natural slope to ensure we build a stable base that drains water away from your home foundation.
