Timber Retaining Walls
Timber retaining walls are cheaper than other materials, although they have a shorter lifespan and structural integrity. Treated hardwood, concrete, brick or stone retaining walls are preferable for a longer life span. Concrete retaining walls cost, on the other hand, may be more. Expect additional expenses for retaining walls that need city authorization and structural diagrams, as well as other retaining wall costs that you may be responsible for.
Excavation and drainage needs for your site may also influence the overall cost. Labour and materials are typically quoted on a per square metre basis, with materials calculated using a square meter. A few jobs can be completed in a day, but most may take longer. Retaining walls are essential when you've got sloping ground in your garden that needs support to stop soil erosion.
