For you to know
The legs need to be set in the ground so the finished seat is 450mm high.
Here’s how
Step 1

Clear the garden bed of all debris. Here, all the pebbles were removed and reserved for later use. Rake over the soil to roughly level it.
Step 2
Choose the bench seat location in the bed, then measure 2 points about 60-70 cm apart and mark the centre points for the leg positions.
Step 3

Dig holes for legs about 250mm deep.
Step 4

Position seat legs in holes and check tops are level with each other.
Step 5

Pour quick-set concrete and water into holes around legs. Allow the concrete to set according to the packet instructions.
Step 6

Apply adhesive to the top of the legs, keeping it away from the edges.
Step 7

Ask someone to help you carefully lower the heavy sandstone capping onto the legs. Let the adhesive set.
