Fully retaining gravity walls can be made from specially treated wood..this one is 25ft high!
These walls are quite easy to construct with a small crew, they are light weight and adaptable.
We have found that adding small planting ‘burrito’ works really well. The timber weathers much better if covered with planting, it helps to prevent the wood twisting, the planting looks really attractive.
