Secondary Drainage

SAND SLITTING
Sand slitting enables the surface water to perculate much faster into the primary drainage system.

Sand slitting can be carried out on all grass surfaces, e.g. golf courses, football, rugby, pitches, race courses, etc…

The sand slits are typically 50mm wide and 250-300mm deep and are installed at 1 or 2 metre spacings.

The sandslits are backfilled to within 150-200mm of the surface using a clean granular backfill and then topped off with a medium to coarse sand.

In order to put the sand slits in we use the tractor mounted Shelton wheel trencher and Shelton backfill hoppers. The specialist equipment means that the slits are dug with very little disruption to the existing turf .
