You may want to build a retaining wall to help support your home’s foundation on a downhill side, or you may do it on an uphill side helping to keep erosion in check.
Sometimes a retaining wall is to manage a steep pitch on a slope and give some level ground. Not only is mowing the grass on a slope difficult, it can be downright dangerous.

In any situation, a retaining wall may be holding back several tons of weight when the soil is saturated.
For this reason, try to keep the height of your wall to under 3-1/2 feet. That’s the height and soil weight you as a do it yourselfer can manage. If your slope is calling for a taller wall, try terracing it and breaking it down into a series of walls rather than one big tall one.

It is highly important to allow for water to drain through or under a retaining wall. Too much build up of water behind it will cause it to collapse.
There are different materials you can use to build a retaining wall and they vary in cost as well as skill level required to build. One of these should suit you.

A
wood or timber wall
is pretty easy to build and the treated lumber is fairly inexpensive too. You can easily build these to allow water to drain through.

A mortared brick or block wall has a neat finished look but is the most labor intensive to build.
If you live in a climate that gets cold in the winter, you’ll have to dig a footing up to a few feet down in some places, to get below the frost line. You will also have to plan in drainage holes since the water cannot easily seep though mortar.
