I have a long sloping garden from the house to a small wooded area. The previous fence fell down due to old age or so I thought! However since having a new fence put up a few years ago it has become evident that there is soil erosion as the metal posts are now at the edge of this vanishing land!
I also thought that a gabion wall may improve sound-proofing from the nearby dual carriageway.
In addition to this problem the high hedges, surrounding tall trees and fencing mean the garden rarely gets full sunlight and I find it really difficult to get clothes dry unless its a baking hot day such as today.
I was wondering how expensive it would be to use gabions to both act as a retaining wall and to build up the level of the garden?
How deep would I need to go to provide retentive properties? Would this be particularly difficult in a wooded area?
If I was to use gabions could i somehow attach fencing to the outer wall to give extra security?
Could I then plant trees/shrubs on top of the gabions? What depth of soil would I need to be able to plant for example rhododendrons? Would I have to effectively create raised beds to accommodate this? How much length of the garden would I effectively lose to build this barrier and to provide sufficient depth and width for planting of substantial shrubs?
Can gabions be built upon for example a summerhouse or used safely as a driveway?
I imagine it would not be too difficult to lay a lawn over gabions by gradually decreasing the stones within the gabions with a mesh such as that to prevent weed growth to retain the stones, gravel then top soil before finally turf.
If you had an outer circuit of gabions could you then build up the centre with hardcore, then gravel and top soil to effectively give a sunken area to the garden?
Can gabions have decking laid on top of them?
How stable are gabions?
Any other ideas and suggestions please ???
