What Goes Wrong & Why
Skipping steps in site prep is where most court problems start
The failure modes below are not rare, they show up on courts where the ground phase was rushed or skipped.
Unverified Slope
A yard that looks flat can carry a grade change of several inches across a court footprint, causing drainage to run toward the surface rather than away from it.
Full-Area Slope Check
A slope check is run across the entire footprint before staking, so grade corrections are built into the excavation plan from the start.
Clay Soil Left In Place
Raleigh’s clay-heavy soil holds water and shifts seasonally, leaving it as the subgrade without assessment leads to base movement and surface cracking within a few years.
Soil Assessment First
A soil assessment determines excavation depth and whether the subgrade needs amendment before any gravel base material is spread.
No Drainage Plan
A court built without drainage pipe or a planned runoff slope will pool water after Raleigh’s summer rain events, softening the base and shortening the surface life.
Drainage Pipe & Slope
Drainage pipe is installed where the site assessment identifies water movement risk, and the subgrade is shaped to a consistent slope that directs runoff clear of the court.
Loose Base Material
Spreading gravel without compacting it in lifts leaves voids that collapse under load, causing the surface above to crack and settle unevenly over time.
Compaction in Lifts
The gravel base is spread and compacted in measured lifts, and compaction is verified before the base is considered ready for a concrete or asphalt pour.
The process starts with a site measurement and layout staking to confirm the court footprint fits the available space with adequate clearance on all sides. Slope is checked across the full area, because even a yard that looks flat often has grade changes that affect drainage. Raleigh’s clay-heavy soil holds water and shifts seasonally, so a soil assessment at this stage determines how deep the excavation needs to go.
Clearing and excavation follow: tree roots, debris, and existing material are removed to the required depth, and the subgrade is shaped to a consistent slope. Drainage pipe is installed where the site assessment identifies water movement risk, directing runoff away from the court footprint. The region’s summer rain patterns make this step critical, a court without planned drainage will pool water and degrade faster.
Once the subgrade is shaped and drainage is set, a gravel base layer is spread and compacted in lifts to prevent future settling. Compaction is verified before the base is considered ready for the next phase. Retaining edges are installed where the court meets a grade change, keeping the base material contained. Only after this sequence is complete is the site ready for a concrete or asphalt pour.

Wake County’s clay conditions are factored into excavation depth and drainage planning on every residential job.
Backyard to Commercial Scale
The same evaluation and base-prep process applies whether the site is a backyard, an HOA facility, or a school property.
Final Walkthrough Sign-Off
The completed base is walked through and confirmed before the next phase of the build is scheduled or started.
The Process
From first enquiry to a base that is ready to build on
Do I need site prep before building a sports court?
Yes, every court build requires site preparation. The ground must be graded, compacted, and properly drained before any surface goes down. Skipping this step leads to cracking, settling, and uneven play surfaces within a few seasons. Every project starts with an on-site evaluation to determine exactly what prep your specific yard needs.
Can my yard be used as-is for a new court, or does it need grading?
Almost no yard is ready as-is. Most residential lots have enough slope, soft spots, or drainage issues to require at least some grading. The on-site evaluation identifies what your yard actually needs, so you get a clear picture before any work begins rather than surprises mid-project.
How do I know if the space is big enough for the sport I want?
A standard pickleball court needs roughly 30 by 60 feet of clear space; a half-court basketball setup needs at least 42 by 37 feet; a full tennis court needs 60 by 120 feet. The on-site evaluation measures your available area and accounts for fencing setbacks, so you know exactly what fits before committing.
Will you check for drainage problems before the court goes in?
Yes, drainage is assessed during the on-site evaluation before any work is quoted. Poor drainage is one of the most common causes of court failure, so identifying low spots, runoff paths, and soil permeability upfront is a standard part of the process, not an add-on.
What if my soil is soft or uneven under the court area?
Soft or uneven soil must be addressed before the base goes in. The fix typically involves excavating to stable ground, adding compacted aggregate base material, and re-grading to the correct slope. Building over soft soil without correction causes the court to settle and crack, often within the first year.
Can tree roots or buried debris cause problems for the court base?
Yes. Tree roots continue to grow after a court is built and can lift or crack the surface from below. Buried debris like old fill, stumps, or rubble creates voids that lead to settling. The site evaluation looks for these issues, and any roots or debris in the build zone are removed before the base is laid.
What happens during court site preparation?
The crew clears the area, removes vegetation or existing material, excavates to the required depth, and grades the ground to a precise slope for drainage. A compacted aggregate base is then installed before any surfacing begins. Each step is sequenced so the finished base is stable and ready to hold the surface layer long-term.
How much clearing or excavation might be needed on my property?
Clearing and excavation scope varies by lot condition, but the itemised written estimate you receive after the on-site evaluation breaks out base preparation costs separately so you can see exactly what site work accounts for. Overall project investment typically runs $2,500-$7,500, with site conditions being one of the main variables.
