For you to know
The legs need to be set in the ground so the finished seat is 450mm high.
Clear the garden bed of all debris. Here, all the pebbles were removed and reserved for later use. Rake over soil to roughly level it.
Choose the bench seat location in the bed, then measure 2 points about 60-70cm apart and mark the centre points for the leg positions.
Dig holes for legs about 250mm deep.
Position seat legs in holes and check tops are level with each other.
Pour quick-set concrete and water into holes around legs. Leave concrete to set.
Apply adhesive to top of legs, keeping it away from the edges.
Carefully lower sandstone capping onto legs, making sure it is centred. Let adhesive set.
