Retaining Walls help stabilize the ground behind them when designed properly. They can help increase usable space on a property. Knowing how to analyze them properly and design them efficiently can prevent problems and save money during construction. Even for small projects, standard plans can cost the owner thousands of dollars in construction over a customized design. A properly designed retaining wall should support the soils behind it, drain ground water properly, resist overturning and sliding. There are lots of factors that go into designing and retaining wall many contractors may not consider.
