Alternatives to Retaining Walls
When it comes to a change of gradient in your land most people just thing ‘Retaining wall’.
Perhaps you should think about some alternatives using a slope.
What you need to consider is how to make sure at that erosion is prevented when rainfall gets washed down the slope.
A great example is this slope has been protected by large boulders carefully placed to appear like a natural rock outcrop.
Another approach is to construct something like a drystone wall but laid back at an angle of around 45 degrees like this second example.
For more inspiration just try Google Search ‘Rockery’ for hundreds of ideas.
