Why It Makes Sense to Construct a Retaining Wall

If you have a hill or a mountain behind your home, you may want to consider building a retaining wall. A retaining wall is simply a structural feature that holds back a naturally sloping patch of earth. Rather than long, winding natural elevations, retaining walls let you step up to naturally sloping ground without mixing the two. They’re typically made out of different materials and can range from several feet to several yards in height.

Traditionally, Retaining Walls located in Adelaide were constructed with sizeable solid rock blocks. The holes would be deep enough to hold the blocks but not deep enough to cause the blocks to lose their hold or slip over the edge of the retaining wall. These blocks should have been arranged to remain in place without falling or knocking into each other. After the blocks’ initial installation, the holes would be filled in to make sure the stones wouldn’t erode.


Today, there are several alternative ways to construct a retaining wall. For instance, stone block walls can be built using smaller pieces of stone that interlock. The blocks can be arranged in various ways to look just like a regular wall, including flat and slanted blocks. There are also modular block walls available which can be disassembled and used elsewhere if needed. It’s important to remember that if the wall is going to be exposed to moisture, exceptional drainage should be installed under the house’s footers.

In cases where you don’t have a natural hill to install a retaining wall on, you can try landscaping around it. One way is to build a barrier along the top of the hill. Another option is to create a retaining wall from a high stone that faces a yard with a good amount of saturation soil. If your bill doesn’t have any hillsides, you can try building on the flat top of a mound of clay soil or mixed with some sand or gravel.

When constructing Retaining Walls located in Adelaide, it’s important to remember that the base should be level and flat. This allows for proper levelling of the footing when the wall is first installed. If you have a steep hillside, the footing should also be carefully considered. You should have a footing test completed before beginning construction. If the test results indicate that you will need to add a concrete footing, you should plan on the cost of doing so.

Depending on the type of surface you are working with (natural or concrete), the retaining wall’s distance to the frost line should be determined. If you are building from natural hilltops, you may build up to three feet away from the frost line. In most cases, the gravel must be as deep as possible at the frost line to channel the water away from the foundation.

Once you determine where you want to build the retaining wall, it’s time to choose the materials you will use to construct it. You have several options, but the most popular are gravel, sand, and cement blocks. Although you can build a nice-looking retaining wall without these materials, they don’t offer as much structural support as the other materials do. Plus, if you are not going to use it as a steppingstone for walking down from your home to your garage, the cost will add up.

Regardless of what material you choose to build your retaining wall from, you should consult with your local building codes to determine the recommended specifications. These codes are designed to keep water flowing properly and minimize damage to the foundation’s soil. Different states have different requirements as well, and you should contact your local planning and building department to find out what is required for your area. If you are building a retaining wall used for backfilling, you need to get it done according to local building codes to ensure it will stand up to future generations.
