Retaining Wall

Retaining walls are very versatile and uniquely designed structures that hold soil on one side and are free-standing on the other. This type of wall can help you work with uneven topography and changes of grade in a landscape. Proper retaining wall design and construction can help make usable space out of a steep slope, provide a place for landscape plantings and even create a level area for a driveway.

On level ground, retaining walls can be used to create an elevated planting area that has improved drainage while creating a place for seating. With proper retaining wall design, you can build a long-lasting and functional structure that will add value to your home or business.

Although a retaining wall may seem like a fairly simple structure that anyone can put together in an afternoon, it is far from simple. Designing and constructing a retaining wall that withstands the test of time requires someone with the knowledge of lateral earth pressure, which is the pressure developed by backfill.

Key Retaining Wall Design Considerations

A variety of important considerations go into the planning of a new retaining wall. You first have to decide the height and length of your wall, and the area where your wall will be placed. Your wall must be the proper height for its location on the slope. It must also have properly compacted backfill, a suitable base and efficient drainage. If you leave out any of these important elements, you may end up with a wall that fails, collects water or is unsafe.

Suitable Base and Foundation – The base of your retaining wall sets the stage for the finished project. You should start with a suitable base material that is both solid and level. If possible, use soil that has not been used in a landscape environment before this project. This type of soil is sturdier and better suited to supporting a retaining wall. Your excavation contractor should dig the base well below the grade and then add a solid and level foundation. By starting with a level foundation, you can avoid having to use shims that take more valuable time and can reduce the structural integrity of your wall.
