Secondary Drainage
Drainage – Excellent drainage is essential for a superior sports turf. There are no sites where natural drainage suffices: supplementary drainage needs to be undertaken to ensure the sports turf does not become unplayable causing postponed matches.
Secondary drainage (for pitches which have received primary drainage but are not up to modern specifications)
Gravel Branding
This process installs a gravel drain filled to the surface at 400mm centres (intervals) providing an intensive surface drainage system, which moves excess water in minutes to the network of primary drains below.
This process leaves the surface immediately playable after installation, however it is preferred to allow the gravel bands to be grown over. Normally this takes 4-6 weeks during the growing season. This method is one of the most cost effective solutions to problematic areas.
Sand Grooving
This process places a continuous groove of sand 25mm wide throughout the playing surface at 200mm centres (intervals). Selected sand is packed into the grooves by specialist equipment.
The sand grooves form continuous vertical channels which are very effective in reconnecting the surface with the underlying secondary drainage system such as sand slits or gravel banding which may have become capped. This increases the speed of the water removal from the surface and develops a better sward. The surface is playable immediately after our specialist machines leave.
Sand slitting
This uses a tractor mounted machine to cut a trench through an established surface at any required centres. This trench is then backfilled with a clean drainage stone, and then topped to the surface with selected sand. The trench provides a connection from the surface to the primary drainage layer. This method cause’s minimal damage to any established surface as the system is tractor mounted.
