To build a retaining wall on a slope, read The Complete Guide to Retaining Walls. It will show you how to plan for the wall’s height, types, and maintenance. We’ll also cover the costs:
- Measure the size you’d like the wall to reach.
- Drive wooden stakes into the ground at the ends. Tie string to each stake at the height you’ve set. Make sure the stakes are about eight feet apart.
- Use a line level to measure the height and width of the wall.

Build a retaining wall on a slope
To build a retaining wall on a slope, you must dig a trench that extends deep into the hillside. The trench should be at least 12 inches deep. Then, place a drainpipe at the back of the trench at the lowest point. This will serve as the foundation for your retaining wall. When digging a trench, ensure you start at the lowest point of the slope and work upwards.
To level the retaining wall, first, place a layer of sand or gravel on the base of the slope. Make sure you tamp down the gravel after each row of blocks. This prevents the retaining wall from tipping over if there are gaps between blocks. After that, add additional partnerships in the same manner as the first row. You may want to stagger the seams of the blocks, so they are even.
Types of retaining walls
There are different types of retaining walls, each of which serves different purposes. While all kinds of barriers are essential, some are better suited for certain situations than others. The purpose of a retaining wall is to hold soil in place. These walls are typically made of reinforced concrete. They have various features, such as reinforcement, including a batter that provides horizontal load-bearing capacity. These walls also have different aesthetics, depending on the type of construction and the desired design.
Concrete and brick are the most commonly used materials for retaining walls. While they are famous for maintaining yards, they require good drainage and skilled installation. A stone retaining wall is stunning but needs a professional mason to install. It also offers a great range of color choices. However, a brick or stone retaining wall may be the best choice if your yard is steep or sloped.
Costs of retaining walls
The cost of retaining walls can vary depending on the size and complexity of the design. Generally, a retaining wall will cost between $250 and $ 550 per square meter in Sydney. Additional costs for excavation, if necessary, will also be affected. Also, some contractors charge an hourly rate, adding to the overall cost. Ultimately, the size of the retaining wall and the materials used will determine the price.
A survey of state transportation engineers reveals the costs of earth retaining walls. Costs are reported in dollars per square meter of the wall face, including the footings and facing, backfill, drainage, reinforcement, finishing details, and the contractors’ or manufacturers’ markup. Costs are consistently higher for high-rise walls than for low-rise structures. The cost of retaining walls has risen four to five times over the past 25 years, although there are still no national statistics.
Maintenance of retaining walls
The proper maintenance of retaining walls is vital to keep them looking their best. Once a year you should inspect your retaining fence once a year to see if any stones have come loose or if roots are growing between them. Look for signs of water seepage, movement, or cracks, as these can indicate that your wall may need to be reinforced. Maintaining a healthy ground cover along the retaining border is essential to re-absorbing water. Finally, you should remove weeds from the retaining wall, as they can penetrate its crevices and cause damage.
To ensure your retaining wall remains safe and in good repair, you should conduct periodic inspections and hire a professional with relevant expertise in structural engineering. In New York City, a registered design professional is needed to make repairs and file a report. The report should also have a certification from an engineer attesting to correct all conditions. Otherwise, you may be held responsible for the damage to your property.
Choosing the right retaining wall blocks
When building a retaining wall, choosing the correct blocks for your specific project is essential. The first retaining block you lay will set the tone for the rest of the project. It must sit appropriately on the base layer and not squeeze loose material. The following blocks should be level, from front to back and side to side. Even a slight difference can cause the next row and level to be uneven. The following steps will help you choose the right retaining wall blocks.
Concrete block retaining walls are a great choice because they naturally resist fire, rot, and temperature changes. As a result, they can protect your property and add value to it. There are three main types of concrete block retaining walls. Learn more about each of them to find the one that best fits your project. You may also want to consider using a combination of both. For example, choosing a block that mimics a natural stone wall from your local area will save you transportation costs and help conserve resources.
