Flatness and drainage are separate checks
A court can look flat and still pond. Survey local undulations and the overall drainage path rather than relying on visual inspection.
KNOTTR CIVIL INTERFACE
3x3 basketball court base and drainage planning.
The playing surface cannot correct a failed supporting base. Base flatness, water management, cracking and perimeter transitions should be known before the sports surface is released.

PLANNING REFERENCE
Resolve the project logic before selecting the exact products.
This page answers one narrow planning question. Use the Technical Centre and Project Brief for the complete 3x3 system.
Modular surfaces still need civil quality
Perforated or open-grid systems allow water movement through the playing layer, but water still needs a stable base and a controlled route away from the court.
Repair before covering
Cracks, failed joints, local depressions and unsafe perimeter steps should be assessed before the final sports surface is installed.
PROJECT CHECK
Information worth confirming before the brief moves forward.
Identify base type and age
Survey flatness and low spots
Confirm drainage outlets / direction
Assess cracks and joints
Resolve edge transitions and local civil responsibility
