Spreading the footings
Spread synthetic fibres or geotextile footings evenly across the sand layer.
Watering the surface
Water the top layer to bring moisture into the footings and sand before mixing.
Mixing the surface
Mix the surface with a power harrow to a depth of 3 inches (7 to 8 cm).
Maintenance
To compact the surface, you can use a power harrow equipped with a roller.
An arena groomer is the perfect machine to use for maintenance.
