Solar Field gravel driveways and drainage culvert installation.
Marsella also installs Gravel Cover for Fire Mitigation in Pole Yards.
Marsella Sand & Gravel installs gravel driveways and access roads for Solar Fields in a 5-state area including Minnesota, North Dakota, South Dakota, Wisconsin and Iowa.
Gravel is primarily used to support heavy equipment during construction and provide durable access for ongoing maintenance.
- Perimeter Roads: Most 1 MW solar units include a 4-meter-wide gravel road around the exterior for construction and operational access.
- Installation Process: Proper installation involves removing topsoil (typically 4–6 inches), laying a geotextile fabric to prevent soil mixing, and applying a subbase of clean gravel followed by a compacted layer of crusher run.
- Culverts and Drainage: At least two culverts are usually required at property entrances to allow water passage and prevent erosion.
- Soil Stabilization: For heavy traffic areas like laydown yards or crane pads, contractors may use stabilizing agents (cement, lime, or fly ash) to create a stronger foundation.
Marsella Sand & Gravel also installs Gravel Cover in Pole Yards for Fire Mitigation.
Gravel cover is a highly effective, non-combustible ground cover used in solar field pole yards for fire mitigation, offering a proactive solution to protect infrastructure from wildfires and onsite electrical fires. By acting as a firebreak, gravel inhibits the spread of fire in pole yards by removing fuel sources, such as dry vegetation and wood mulch, which are common catalysts for flame propagation.
The Key Benefits of Gravel use for Fire Mitigation.
- Fuel Elimination: Gravel provides a non-flammable surface that prevents the growth of dry, "flashy" fuels like tall grass, which can ignite from a single electrical spark in a pole yard.
- Strategic Firebreaks: Gravel is used to create critical firebreaks around high-risk infrastructure, including:
- Project Perimeter: A 50-foot buffer of gravel with no vegetative fuel.
- Inverter Pads: A 10-foot radius cleared of vegetation and covered with landscape fabric and gravel.
- Tracker Poles: A 36-inch "clear zone" at the base of each pole.
- Access and Maintenance: Gravel provides stable, all-weather access roads that double as firebreaks for emergency responders.
