How to Build a Retaining Wall with Concrete Blocks: Learn how to build a retaining wall with concrete blocks by calculating materials and get started building your own retaining wall.
Concrete is the most popular material for retaining walls, in part because of how low-maintenance it is. Concrete will not rot or rust and it holds up against weather and temperature changes much better than other materials that can be used to build retaining walls.

Retaining walls are a great way to add usable space to your property, and they can be built quickly and cost-effectively. They’re also fairly easy to design, although you’ll need to take into account several factors before you begin.
If you’re planning on building a retaining wall from scratch, or adding one to an existing structure, there are two main types of materials that can be used: concrete sleepers and concrete blocks. Both offer their own advantages and disadvantages, so it’s important that you choose the right one for your project.
Building a retaining wall using concrete blocks is relatively straightforward because they’re designed specifically for this type of work. They’re also easy to cut and drill into if you need more space or want to accommodate cables and pipes in your design.
The biggest disadvantage when compared with concrete sleepers is that blocks are less durable over time because they don’t have any reinforcement inside them – so they won’t last as long as sleepers would if subjected to weathering or other factors like frost damage.
The most common type of retaining wall is constructed from concrete block or wooden sleepers. The blocks or sleepers are fitted together with mortar, which is then sealed with render to make the wall waterproof.
The first step in building a concrete block retaining wall is to mark out your foundations. This will be dependent on how high you want your wall to be, but it should extend at least 300mm beyond where the top of the wall will be, so that there’s room for a gravel base.
Once you’ve marked out your foundations, dig them out using a spade and level them using a spirit level. Next, lay down some gravel (or hardcore if you prefer) so that it covers the entire area of your foundation trench.
Now place some concrete blocks on top of this gravel base and use a spirit level to ensure they’re straight. Once all of the blocks have been laid down in this way, take up any excess gravel by placing more concrete blocks on top of it until there’s no sign of any gaps between each one. You might find it easier to use builders wedges instead of trying to fill gaps with small stones as these tend not to work well!
How to Build a Retaining Wall With Concrete Blocks
Building a retaining wall is one of the best ways to control erosion and keep your yard looking tidy. A concrete block retaining wall is an inexpensive option that requires minimal construction skills. You can build one yourself with basic tools in about two days.
Step 1: Mark the Location of Your Retaining Wall
Use stakes and string to mark out the location of your wall. The top of the wall should be about 4 inches above ground level, so you’ll need to dig down into the soil at least that far to install it. If you’re placing your wall between two driveways or other paved areas, you may be able to use those surfaces as reference points instead of using stakes and string.
Step 2: Dig Holes for Concrete Blocks
Dig holes for each concrete block along one side of your marked-out area. Make sure each hole is deep enough to accommodate the length and width of your block plus 3 inches of dirt on top, but don’t go beyond this depth until all blocks are in place — otherwise they won’t line up properly with their neighbors.
A retaining wall is a structure designed to resist the lateral pressure of soil, which otherwise might move the construction away from its intended location. Retaining walls are traditionally made from masonry materials such as brick or stone, cement blocks, or poured concrete.
Retaining walls are used for many reasons:
To hold back earth to create level ground for a house foundation.
To protect from erosion and landslides.
To support raised flowerbeds and vegetable gardens.
To support a balcony or patio above ground level.
If you have a hillside that’s prone to erosion or you’re looking to add more usable space to your backyard, a retaining wall is the perfect project. It’s easy to build and relatively inexpensive, but the real benefits are in the long-term.
This guide will show you how to build a retaining wall with concrete blocks, sleepers and posts.
Step 1: Prepare the area
Before you can start building your wall, you need to prepare the ground by removing any dirt or grass and leveling it out so it’s flat and even. You may also need to create support beams for the base of your wall if it’s on an incline. If this is the case, dig trenches along the base of your walls where they will sit and place stakes into them.
Step 2: Prepare your materials
To build a retaining wall from concrete blocks, sleepers and posts, gather all of your materials before starting construction so there isn’t any downtime midway through building it. You’ll need concrete blocks for each tier of your wall, wooden sleepers for connecting them together (or metal ones if using concrete blocks), concrete posts for anchoring each tier into the ground and mortar mix for attaching everything together
How to Build a Retaining Wall With Concrete Blocks
Retaining walls are structures that keep soil from moving. They’re commonly used in landscaping to hold back earth and rock. A retaining wall is usually made of concrete blocks, although you can use bricks or stones as well. These walls are generally built on a slope to help hold the ground in place. If you’re planning to build your own retaining wall, here’s how it’s done:
Step 1: Choose Your Blocks
Choosing the right blocks for your project is important because it will impact how much money and time you spend on your project. You’ll want to choose blocks that are easy to work with and that match what you want for the finished product. You’ll also want them to be sturdy so they don’t fall apart when you’re building your wall or even after it’s been standing for awhile.
Step 2: Preparing the Ground
If you’re using wood sleepers instead of concrete blocks, then this step isn’t necessary — but if you’re using concrete blocks, then it’s essential that they’re at least level with one another before they can be added to any wall. Use a spirit level and adjust as necessary until each sleeper is level with all others
Retaining walls are used to stop soil erosion and control water flow in residential and commercial landscaping. They are also used to hold up terraces, walkways and patios.
Retaining walls can be built with wood posts or concrete sleepers. Concrete sleepers provide a more permanent and sturdy wall than wood posts. In addition, they are less expensive than other materials like brick or stone.
To build a retaining wall with concrete blocks, first determine how high you want the wall to be. The height of your retaining wall should be equal to the width of each block multiplied by the number of blocks used in the wall. If you wanted a 10-foot tall retaining wall with four blocks wide by 10 blocks high, then each block would be one foot high by four feet long by 10 feet long (10’x4x10′).
The next step is to layout your design on paper before starting construction on site. This will allow you to see where each block will go before digging into the ground and wasting time or money on mistakes that could have been avoided with proper planning ahead of time!
how to build a retaining wall with concrete sleepers
1. Dig out the area where the wall will be installed. The width of the base should be about twice as wide as the wall itself, and it should extend below ground level by at least 10 inches.
2. Place a layer of crushed stone or gravel at the bottom of the excavation area, then compact it with a tamper.
3. Pour concrete into the trench and spread it over the entire area with a trowel or broom.
4. Smooth out any imperfections in the concrete surface with a float, then let it dry for three days before you begin building your retaining wall.
A retaining wall is a structure that holds back soil or other materials. They are often built to prevent soil erosion, to keep soil in place for construction, or to create level ground for a building or other man-made purposes. The most common types of retaining walls are made from concrete and masonry materials. Retaining walls are typically built on sloping surfaces, such as hillsides and terraces.
Retaining walls are used extensively in civil engineering projects such as dams and levees. In addition, they’re used to hold back earth in underground excavations such as mines. They can also be incorporated into the design of highways, where they help prevent landslides from blocking traffic on steep grades.
