The builder starts with a laser level site survey and slope check. Los Angeles County hillside lots often have terrain that looks manageable but requires significant grading to reach the slope tolerance a court surface needs. Edge setback planning is done at this stage so the layout stays within local lot-coverage rules and the usable court area is confirmed in writing before any ground is moved.
Southern California clay soil retains water and shifts seasonally, which makes compaction and drainage checks especially important. Excavation removes unstable material, and a compacted aggregate subbase is built to the depth the surface type requires. Drainage lines are placed during this phase, not added later as an afterthought, so they integrate with the subbase and slope correctly toward the exit point.
An existing slab is evaluated for cracks, slope, and surface adhesion before any new material goes over it. If the slab is sound, it can often serve as the base layer. If it has moved or drained poorly, the builder documents the issue in the written scope so the repair is addressed before surfacing begins, keeping the project on schedule.

Do I need site preparation before building a sports court?
Yes, every court project requires site preparation. The ground must be graded, compacted, and drained correctly before any surface goes down. Skipping this step leads to cracking, pooling water, and an uneven playing surface that worsens over time. An on-site evaluation confirms exactly what your specific ground needs.
Can my existing concrete slab be used for a new court?
Sometimes yes, but the slab must be assessed first. Builders check for cracks wider than a hairline, surface heave, drainage slope, and structural integrity. A slab in sound condition with adequate slope can often be resurfaced directly. One with significant cracking or poor drainage usually needs repair or replacement before a new surface is applied.
Is my yard flat enough for a court project?
Most yards are not perfectly flat, and that is normal. Grading during site prep corrects the slope to the required tolerance. What matters is whether the existing grade is close enough that grading is practical, or so steep that major earthwork or retaining walls would be needed. An on-site evaluation gives you a clear answer for your specific yard.
How do I know if my space is big enough for the court size I want?
A standard pickleball court needs roughly 30 by 60 feet of clear space; a half-court basketball layout needs about 42 by 37 feet. Tell us the sport and your available dimensions, and a local builder will assess the site and confirm what fits, including any buffer space needed for fencing or run-off zones.
What happens if the site has drainage problems?
Poor drainage causes water to pool on the surface, which accelerates surface wear and creates a slip hazard. Builders address it during prep by regrading the base to a controlled slope, adding a compacted aggregate sub-base, or installing French drains where the ground cannot shed water naturally. Ignoring drainage problems before construction guarantees they reappear through the finished surface.
Can you tell if the soil will cause problems before construction starts?
Yes. The on-site evaluation checks soil type, compaction, and how the ground responds to moisture. Expansive or clay-heavy soils that shift with water content are identified at this stage, so the base design can account for them before any work begins rather than after a problem surfaces.
What if the base ends up uneven after the work starts?
If grading reveals unexpected soft spots, buried debris, or inconsistent compaction, the builder addresses those areas before the base layer is finished. Continuing over an uneven base would transfer the problem directly to the playing surface, so correction at this stage is standard practice, not an optional extra.
Will site prep help prevent cracking later?
Yes. Most surface cracking traces back to an inadequately compacted or poorly drained base that shifts under load or moisture. Proper grading, a compacted aggregate sub-base, and controlled drainage remove the main causes of that movement, giving the finished surface a stable foundation that resists cracking over time.
