A court needs a consistent playing plane and a workable water-management plan. Those are related but separate goals. Water must leave the surface, upstream runoff must be addressed, and moisture around or beneath the pavement must not be ignored. Adding color coatings or a drain at the lowest-looking corner does not automatically correct a poorly graded site.

Where does the water come from and where will it go?
Start with three sketches: the existing drainage pattern, the proposed finished elevations, and the discharge route. Identify water falling directly on the court, water arriving from uphill ground or roofs, and water collecting around the base. A contractor should be able to show how each relevant source is managed after construction.
Record the proposed outlet and who has authority to approve it. An outlet beyond your property is not merely a convenient line on a drawing. Easements, neighboring improvements and municipal requirements need to be resolved through the address-specific approval process.
| Water problem | Useful evidence | Decision it informs |
|---|---|---|
| Puddles inside the court | Photos after rain, elapsed time, locations and measured levels | Local depression repair versus broader plane correction |
| Runoff crossing the court | Flow paths observed from a safe location during rain | Interception or grading above the court |
| Wet edges or recurring moisture | Irrigation pattern, perimeter grades, drainage inspection | Perimeter correction and further investigation |
| Water leaving toward a neighbor | Existing/proposed elevations and outlet plan | Whether the proposed drainage strategy is feasible and approvable |
| Mud returning after storms | Bare soil, eroding slopes and construction restoration plan | Stabilization and protection of the finished surface |
These are investigation prompts. A photograph cannot identify every subsurface condition or replace a designer’s evaluation.
Is the court supposed to be flat or sloped?
A court can be flat in the sense of lying on a consistent plane while that plane has a deliberate slope. A depression is a local departure from the plane that can hold water. Treating “flat” as “perfectly level” confuses those two ideas and can produce a surface with nowhere for water to go.
SportMaster’s construction cost FAQ describes a one-direction slope of approximately 0.83%–1% as general construction guidance. That is a manufacturer overview, not a complete design specification or a local ordinance. The project designer and selected surface manufacturer should agree on the required slope, direction, tolerances and acceptance method.
To read a drawing, use fall = horizontal distance × slope as a decimal. For example, an illustrative 1% fall across 34 feet is 0.34 foot, or 4.08 inches. Across 64 feet it is 0.64 foot, or 7.68 inches. Those are arithmetic examples, not recommendations to orient every court’s drainage in one of those directions. A stated “one inch in ten feet” equals about 0.833%, not exactly 1%; have the design resolve the intended value rather than relying on interchangeable shorthand.
What should happen beneath the pavement?
The base design begins with the actual ground, proposed loads and drainage conditions. Ask who decides whether existing soil is suitable, how unsuitable areas are handled, and how placement and compaction are verified. A universal thickness copied from a web diagram is not a substitute for that scope.
Before base construction, coordinate utilities, net-post details, fence foundations and any lighting infrastructure that affects the work. Document what will be buried. If equipment must cross a driveway or a confined side yard, identify access restrictions and the restoration plan early; access changes can affect how material is delivered and placed.
At the transition between trades, obtain a documented acceptance point. The surfacing installer should inspect the pavement it will coat, and any required corrections should be resolved before the finish hides the surface. Use the concrete-versus-asphalt guide to compare these responsibilities.
Why can a well-colored court still blister or peel?
A coating’s appearance on opening day does not prove that moisture and adhesion were handled correctly. SportMaster identifies vapor-barrier, perimeter-drainage and surface-preparation considerations for its concrete application in the PickleMaster product guidance. Its maintenance manual also warns that excessive surrounding irrigation can contribute to moisture under the base and blistering through acrylic layers.
For a new court, ask how the specified assembly addresses these conditions. For an existing court with repeated coating failure, investigate before recoating. Merely making the surface look clean and dry at one visit does not establish why the previous system failed.
What is a useful acceptance and handover record?
Before construction, agree on how surface regularity and drainage will be assessed, which standard or manufacturer instructions apply, and who resolves nonconforming work. Record dates and conditions during the assessment. Do not invent an acceptable puddle depth or drying time after a disagreement has already occurred.
A practical owner file includes the final grading plan, drain and outlet locations, concealed-work photos, product information, inspection records and a maintenance plan. Where water testing is part of the agreed procedure, have the contractor explain the method and results. Keep observations distinct from conclusions: “water remains in this marked area” is evidence; “the base is failing” requires more investigation.
Leawood offers a concrete local example of why drainage is an early design item: its currently linked unlighted sport-court packet requires a drainage study prepared by a Kansas-licensed professional engineer. That is Leawood’s published process, not a metro-wide rule.
For a new backyard court, capture these questions in the quote worksheet. For an existing court, combine them with the repair decision guide. The complete planning sequence places this work before final surface selection for a reason: the visible finish depends on the conditions below and around it.
