At Hummer, we understand that drainage isn’t just a fix—it’s the foundation of field performance. Our drainage solutions integrate subsurface pipe networks, sand-slit and sand-channel systems, laser-precise grading, and full-field renovations—working together to eliminate standing water, relieve compaction, and deliver firm, consistent natural-grass surfaces. Whether you’re building new, upgrading heavy-use fields, or correcting moisture issues mid-season, our engineered systems are designed for athletes, schedules, and real-world conditions to keep your field in the game, rain or shine.
For more than three decades, the Hummer Sand Grid System has set the standard for natural turf drainage solutions on high-use athletic fields. Developed in 1990 as a direct response to the chronic drainage challenges facing schools, universities, and municipalities, this proprietary system has been installed on more than 150 fields across the Mid-Atlantic region. Its proven performance has led many clients to outfit entire campuses and athletic complexes with Sand Grid, ensuring their athletes always have safe, playable fields.
Quality control is the foundation of every Sand Grid installation. The system consists of a cross-hatched trench network, each carefully engineered to intercept and move excess water efficiently. Our team uses specialized equipment with flotation tires to minimize turf disturbance and protect existing surfaces. Every sand and gravel material used in the grid is rigorously tested and approved by Hummer staff before installation to ensure proper gradation, permeability, and performance. This attention to detail ensures a system that functions exactly as designed — season after season.
Unlike full-profile sand fields that require high inputs of water and nutrients, the Sand Grid System leaves the native topsoil intact between drainage lines. This allows the field to retain natural moisture and nutrient-holding capacity, reducing reliance on additional fertilizers and irrigation. The result is a field that drains quickly, plays consistently, and remains environmentally responsible.
From high school football stadiums to Division I soccer fields, facilities that adopt the Hummer Sand Grid System experience an immediate improvement in field usability and athlete safety. Many schools and municipalities have seen such success that they’ve installed Sand Grid on multiple fields, creating entire athletic complexes that remain open and playable when competitors’ fields are washed out.
