Techniques:

Primary land drainage is carried out by laying a series of pipes underground and then backfilling with a permeable material such as gravel or Lytag® to allow the rain water to pass through. This type of drainage can be incorporated into large sports fields, football pitches and golf courses using award winning machinery designed by Shelton.

Land drainage pipes fit neatly into the narrow trenches cut accurately by the Shelton Supertrencher's high speed cutting wheel, or Shelton Chaintrencher. The narrow trenches are backfilled using one of our fast-flow hoppers, and topped with a free-draining sand or rootzone, which can be sown with a suitable grass seed mixture, or left to grow in naturally.

Often supplementary to the primary drainage network, secondary drainage systems are installed at 90-degrees to the main pipes below and incorporate a network of drainage slits using a Supertrencher or System 25; or drainage bands using a Gravel Band Drainer, into the upper soil structure. These are closely spaced allowing any excess surface water to drain away much faster.
