Frequently Asked Questions

Common inquiries about field drainage, porosity testing, and micro-climate engineering.

How deep should the gravel layer be under a professional turf field?

The gravel layer typically ranges from 100 to 300 mm depending on local rainfall intensity and soil type. For stadiums in high-precipitation zones, we recommend a minimum of 200 mm of well-graded aggregate with a geotextile separator to prevent fine soil migration and maintain long-term porosity.

What is the ideal spacing for lateral drainage pipes?

Lateral pipes are usually spaced 3 to 6 meters apart. The exact distance depends on the soil’s saturated hydraulic conductivity and the target drainage time. A herringbone layout with 4-meter spacing and a 1% slope is a common starting point for natural turf fields.

How do you measure soil porosity on an existing pitch?

We use a combination of double-ring infiltrometers to measure surface infiltration rate and core sampling to analyze bulk density and pore distribution in the lab. These tests give a clear picture of compaction levels and water retention behavior across the field.

Can drainage be improved without replacing the entire turf?

Yes. In many cases, targeted aeration, sand slitting, or installing additional lateral drains can significantly improve water removal without a full reconstruction. We first run a porosity audit to identify the specific bottlenecks before recommending a retrofit plan.

What role does stadium micro-climate play in drainage design?

Local wind patterns, shade from stands, and roof overhangs affect evaporation rates and soil moisture distribution. We factor in these micro-climate conditions when designing pipe networks and selecting aggregate gradation to ensure consistent drainage across the entire playing surface.
