Our Services> Top Draining
Our Koro Top Drain is unmatched when creating sand-filled drains in turf surfaces.
Sand-filled trenches, or sand slits or interceptor drains allow surface water on the turf surface to be promptly removed in the profile and carried off-site via the previously installed sub-base, piped drainage system.
The machine cuts the trench, backfills it with sand then compacts it, all in one pass, completing the process three trenches at once.
The trench dimensions of:
200mm depth (enough to meet the carrier drainage in most cases) 40mm width (thin enough to ensure the surface does not become `droughty`) 500mm spacing (allowing 40% of the soil profile to be drained) are significantly more effective than competing methods.
