There are many factors to consider regarding the design and construction of running tracks and sports fields, but one aspect that will ensure track longevity is addressing the need to evacuate water off the track surface. A track left with standing water causes major damage to the surface over time, delaminating the synthetic surface and asphalt base and severely shortening its usable life.
Surface drainage options include area drains, french drains/open swale or modular perimeter trench drains. Area drains and french drains have an irregular surface, are prone to ponding, difficult to maintain and have poor hydraulic performance. A modular perimeter trench drain is versatile and quick and cost-effective to install while being highly efficient and easy to maintain. These five steps will help to identify the proper trench drainage system for your track/field facility and ensure sporting events to continue without delay or cancellation.
1. Hydraulics – It’s important to evaluate the hydraulic performance of the trench drain, or the ability of the drain to evacuate water without flooding.
3. Material – Modular sport trench systems are available in polymer concrete or plastic materials. While the drain body may not be visible once installed, the choice of material is important when evaluating loading requirements, ease of installation (product weight) and the effect of climate changes on the material, such as in freeze-thaw environments.
4. Aesthetics/Security – The facility or type of events may dictate an aesthetic requirement. Several grate designs and materials are available. For a grated drainage system, a number of grate locking options are available, depending on the need for easy removal for maintenance.
5. Legislative/Safety – Depending on traffic conditions, it may be necessary to comply with ADA requirements. Other safety issues may need to be considered for the facility, such as needing to accommodate high heels or bicycle traffic.
