Retaining walls are used to maintain bottom surfaces of land at different elevations. These walls help to preserve soil from eroding or collapsing and bring the soil back up as backfill. They are made of a variety of materials, including concrete blocks, poured concrete, treated timbers, and boulders or rocks. Rigid holding structures, also known as cantilever walls, are also available.

Build a retaining wall

Before you start building a retaining walls, there are a few things to remember of adelaide northern fencing. Consider the location where you plan to build the wall. Some areas have strict building codes and may require a building permit. Also, you’ll need to consider the slope of the area to determine how much soil needs to be retained. Different types of retaining walls are available to meet your needs. There are gravity walls that hold the soil back with only stones, and others made with steel bars.

A retaining wall should be positioned so that it leans into the hillside at a ratio of one inch to every twelve inches. Deadmen anchors should be used to tie timber walls four feet high or more to the hillside. These anchors are rectangular pieces in the T-shaped shape that extend 6 feet backwards to a 2-foot-wide T-bar.

Drainage provisions are important to avoid excessive pressure on your retaining walls’ backside. Perforated drainpipes, available at home improvement stores and other outlets, can be installed to carry groundwater to the walls’ ends. If you don’t want to put down perforated drainpipe, you can also install drain tiles.

If you’re not a skilled DIYer, hiring a professional to build your retaining wall is an option. Retaining walls can be a great way for your property to be more stable, no matter how handy you are. Drainage pipes are a good idea for tall walls. This will allow the backfill to breathe. You should also check your retaining wall for unevenness. To achieve an even surface, it may be necessary to dig a narrow trench in your yard or excavate the ground.

You should consult the local building regulations before building a wall. For example, some communities have rules regarding how high a wall can be. If you are putting up a large wall, you’ll need a permit. These regulations must be followed.

Natural stone is another great option for retaining walls. This stone is eco-friendly and makes an excellent choice for landscaping. The individual stones in natural stone make each project unique. The material is ideal for retaining walls, raised garden beds, and landslide barriers. The materials used for natural stone retaining walls include limestone, fieldstone, and sandstone. Natural stone is also an excellent choice for mortared retaining walls.


There are many materials that can be used to build retaining walls. Some are more durable than others. Brick, stone, and concrete blocks are all great options. However, each type has its advantages and disadvantages. A smaller retaining wall can be made with a smaller material, such as wood blocks or stacked concrete blocks. For larger retaining walls, a stronger material is required to support the weight.

Veneer is another option for retaining walls construction. This type of material is often used to add a decorative touch to the wall. The advantage of veneer is that it can protect your foundation and still offer a great appearance. It requires a solid core. This type of retaining wall works best when used with geotextiles for reinforced soil slopes.

A functional addition to any landscape can be made by retaining walls by landscapers in adelaide. They can serve as a comfortable seating area for the family, a beautiful place for plants, or even the beginning of an outdoor living space. Your home’s exterior should be matched with the materials you use for retaining walls. You can make decorative walls from any material, but you must use durable materials for structurally important walls.

When choosing the material for your retaining walls, you should consider the size, shape, as well as the style. While it can be tempting to use the most inexpensive material available, it’s better to hire an experienced company to ensure that your retaining wall construction meets your expectations. Retaining walls are designed to hold tons of soil. You should make sure that your material is strong and won’t break down. If you’re building a tall retaining wall, you’ll need to consult a structural engineer to determine the best way to construct it. To handle water and prevent hydrostatic pressure, most retaining walls require a below-grade drainage system.

Another durable retaining wall material is plastic lumber. It is lightweight but retains a natural appearance. HDPE plastic can be molded into boards with a surface grain texture that is similar to real wood. It comes in a variety of colors, including brown and gray, which will match the surrounding environment.


Proper maintenance is key to the longevity and safety of your retaining walls. Regular inspections will ensure the integrity of the structure and prevent any problems from worsening. You should keep an eye on the wall for any signs of damage to mortar joints or changes to the landscape. Check that drainage vents are working properly as water can pool near the wall’s base, weakening its foundation. You should also check the railings and fences for stability.

Visitors and residents can avoid dangerous incidents by inspecting the retaining walls for signs of damage or deterioration. It is best to hire a structural engineer who has experience in retaining wall construction. The engineer will inspect the wall and determine what repairs are necessary. It is important to address drainage problems and monitor wall penetrations that are vulnerable. This will prevent costly repairs later.

The New York City Department of Buildings offers a free inspection program for retaining walls. Inspectors check the structure of the wall for signs of bulging or displaced material, as well as leaning walls. If the inspector finds any of these problems, the DOB will defer the violation until repairs or corrective action are implemented.

The WIP manual contains detailed instructions on how to inspect the retaining walls in order to find problems. The manual also includes grading guidelines. The sum of all ratings for elements observed is the final rating. The rating of each element is considered to determine “appropriate wall action,” based on the severity of the distress, engineering of the original design, and potential consequences. Depending on the condition of the wall, the appropriate action could be to replace it, conduct maintenance work or monitor it.

Regular inspections of retaining walls are an important part of preventative maintenance. Failure to do so can lead to costly repairs, and prevent a catastrophic failure. The DOB created Local Law 37 in 2008 after a New York City retaining wall collapse. This Local Law was designed to improve standards for retaining walls construction.
