Do the elements have to be firmly anchored or stabilized on the ground?
It depends on the type of garden edging, size and local conditions.
If an anchor is necessary, this is done with high-quality anchors from the Hilti program. The anchor points are made flush with the bottom and is closed after the removal of a border with threaded plugs which do not protrude above the floor.
If such anchoring is not possible, stabilization, if necessary, can be achieved via weights (e.g., plant pots).
We advise you for the necessary measures.
