A site that drains correctly and compacts to spec means no cracking, no pooling, and no costly fixes after the court is built.

What Goes Wrong & Why
The preparation mistakes that cause courts to fail within the first few seasons
Rushed or incomplete ground work shows up later as cracks, soft spots, and standing water, problems that are expensive to fix after the surface is down.
Slope Not Checked
A court graded beyond 1 percent slope holds water in low corners and creates an uneven playing surface that worsens over time.
Slope Verified to Spec
The builder measures slope across the full court footprint and grades to 1 percent or less before any base layer is placed.
Drainage Path Skipped
Without a confirmed runoff exit, San Antonio’s intense rain events back water up under the court, accelerating subgrade movement and surface cracking.
Drainage Path Confirmed
Drainage flow direction is mapped and verified before excavation, so heavy runoff exits the site rather than collecting beneath it.
Clay Soil Ignored
San Antonio’s caliche and clay-heavy soils expand when wet and contract when dry, causing the subgrade to shift and the surface above it to crack.
Soil Stability Assessed
A soil check is completed before excavation begins, and compacted gravel is added where the native soil cannot support the base load on its own.
Compaction Rushed
Subgrade compacted in a single pass rather than layers leaves soft zones that settle unevenly once the court carries regular foot traffic and weather cycles.
Layered Compaction Used
Mechanical compaction is completed in staged layers, and surface flatness is checked before the site is declared base-ready for the next phase.
Preparation starts with site measurement and layout staking. The builder confirms the court footprint fits the available space with adequate run-off clearance on all sides, then checks the existing slope. San Antonio’s caliche and clay-heavy soils behave differently under load and water, so a soil stability check is completed before any excavation begins.
Grading removes high spots and fills low areas to bring the surface within the required slope tolerance, typically 1 percent or less across the court footprint. Drainage path planning confirms where runoff will exit the site after heavy rain. South Texas rain events can be intense and short, so the drainage path must handle a high flow rate without backing up onto the court area.
Once grading is complete, the subgrade is compacted in layers using mechanical equipment. Compacted gravel is added as a base layer where soil conditions require additional stability. The builder checks surface flatness and drainage flow before declaring the site base-ready. No surfacing work is scheduled until the preparation phase passes that check.

Questions about court design & site preparation in San Antonio
How do I know if my site is ready for a court?
An on-site evaluation checks slope, drainage, soil stability, and available footprint before any work is scoped. Most yards need at least some grading or drainage work, very few are ready as-is. The evaluation identifies exactly what your site needs so nothing is assumed.
Will poor drainage damage the court later?
Yes. Water that pools under or around the court erodes the base, causes the surface to heave, and accelerates cracking. Drainage is planned before the build starts, not added as an afterthought, because fixing it after the surface is down costs significantly more.
How do you make sure the court fits my space with room around it?
The on-site evaluation measures the usable footprint and maps required buffer zones, typically 6 to 10 feet on each side depending on the sport. The layout is marked and confirmed before any grading begins, so the court dimensions and clearances are locked in from the start.
How do you handle slope before the court is built?
Slope is addressed through cut-and-fill grading, retaining where needed, and establishing a 1 percent cross-slope on the finished base to shed water. The method depends on how steep the site is and which direction it drains, both are assessed during the initial site visit.
What clearing and grading are included before the court goes in?
Clearing covers vegetation, debris, and any obstructions within the court footprint and buffer zone. Grading follows, cutting high spots, filling low ones, and compacting the sub-base to a consistent grade. Both are itemised in the written estimate before work starts.
How do you keep the court from ending up too small or in the wrong spot?
The layout is staked and measured on-site during the evaluation, accounting for sport-specific dimensions, buffer zones, fencing lines, and any setback requirements. You review the marked footprint before grading starts, so the position and size are confirmed before anything is moved.
Will the prep work help prevent cracks or settling later?
Yes. Cracks and settling almost always trace back to an inadequate base, insufficient compaction, wrong material depth, or poor drainage underneath. Proper sub-base preparation addresses all three before the surface goes down, which is the most effective way to prevent those problems from appearing later.
Will the prep work help prevent standing water on the court?
Yes. Drainage planning is built into the prep phase, not added after the fact. The base is graded to a consistent slope so water moves off the surface and away from the court perimeter, reducing the conditions that cause pooling, surface degradation, and slippery playing conditions.
