The sub-base represents the structural foundation of a sports pitch and directly affects the performance of the playing surface. Pitch quality does not depend exclusively on the visible turf, but on the workmanship and materials used to create the correct sub-base—a fundamental element for ensuring stability, drainage, and long-term durability.
Sub-base structure
The sub-base structure consists of a stratigraphy of materials designed to support the playing surface and ensure the correct functioning of the pitch. Each layer performs a specific function: from load distribution and water management to soil stabilization. Proper stratigraphy design results in a uniform and stable base, reducing the risk of subsidence and surface deformation.
Materials and workmanship
Material choice and workmanship quality are decisive for sub-base behavior. The aggregates used must guarantee adequate drainage capacity and long-term stability, while the work must be executed with precision to ensure correct compaction and layer continuity. Errors at this stage can compromise the entire system, negatively impacting pitch performance and increasing the need for corrective actions.
Water management and drainage
The sub-base plays a central role in water management, integrating with the pitch's drainage systems. The ability to quickly dispose of rainwater and irrigation is essential for keeping the surface stable and usable even in difficult climatic conditions. Correct design prevents waterlogging and preserves pitch quality over time.
Impact on pitch performance
Sub-base characteristics directly affect the performance of the playing surface. Stability, planarity, and response to stress depend on the quality of the base upon which the pitch is built. A correctly designed sub-base ensures uniform playing conditions, improving the quality of the sporting experience and athlete safety.
Durability and maintenance
The durability of a sports pitch is closely linked to sub-base quality. A stable, well-designed base reduces the risk of surface degradation and allows for optimized maintenance activities over time. Conversely, an inadequate sub-base can lead to frequent interventions and faster pitch deterioration.
Integration with the pitch system
The sub-base must be designed as an integral part of the pitch system, in relation to the chosen surface type—whether natural, synthetic, or hybrid. FLexGrass develops solutions where sub-base design is strictly coordinated with other pitch components to guarantee high performance and continuity of use.
