Contract Trenching

Barth K140 drainage trencher

Our machinery combine to form a land drainage unit, operated by a staff referred to as a "drainage gang".

Barth K140 drainage trencher with 100mm diameter perforated pipe, Case 956 with trench backfill blade & trench backfilled with cockle shell as a permeable medium. The pipe is laid at the bottom of the trench & a 300 - 400mm layer of cockleshell or 40mm aggregate above being finally reinstated with the spoil originally removed from the trench back up to ground level. Chain trenchers generally out-perform an excavator in terms of linier metres covered per day.

Trench grades as set out with a theodolite which are indicated to the trencher driver using boning rods on a "line of site" to give the required "fall" on the drain from the apex of the field to the ditch.
Land drain centres are usually 60feet or 20yards apart, however can be closer in more "ponding" prone areas.
