Burying SWA

hi guys, just looking for a general consensus on the depth to burying SWA in a garden area which would be expected to be maintained by gardening forks and spades etc, I intend to line trench with sand and lay marker tape approx 150mm from the surface, what depth would be acceptable, I'm edging for 600mm total depth

  • Sounds about right. Historically 2 spade height depths which equate to 24" or 600mm for metric depths.

    This is guidance from, if I remember correctly, the OSG and GN1
