How To Build A Small Brick Retaining Wall

If you want to build a retaining wall without a lot of money and time, you can opt for Interlocking concrete blocks. These blocks are self-aligning, trapezoidal in shape, and can be built on slopes as well. To build the walls, you will need to follow certain steps. Here are some of those steps:

Interlocking concrete blocks are the cheapest way to build a retaining wall

These blocks interlock with each other through the application of pressure. These interlocking blocks feature a lip along the bottom rear edge that eliminates the need for mortar. They can be used for walls up to 30 inches tall. These interlocking blocks are available in different colors, styles, and sizes, and are often used for retaining walls of a small size. You will need to prepare the site and add additional materials, such as sand.

Choosing the right retaining wall material is important for the success of the project. For those who are not particularly handy with tools, interlocking concrete blocks can make the process simple. They are available in many sizes, and come in different price ranges. The blocks are versatile and can be purchased separately, and they can be assembled by putting them together using concrete sleepers. They are also available in different colours and materials, and they do not require mortar to hold them together.

Concrete poured walls cost about $20 to $30 per square foot. A retaining wall made of interlocking concrete blocks costs approximately $27 to $30 per square foot. The cost of a stone retaining wall varies from $12 to $30 per square foot, but the cost is a little higher because of the more complicated installation process. These walls can also be painted and last for a long time. Wood retaining walls are beautiful, but they tend to rot and degrade with time.

They are self-aligning and trapezoidal in shape

When building a retaining wall, self-aligning and trapezoidal bricks are the most ideal choice. These blocks are lightweight, self-aligning, and trapezoidal in shape, and they do not require mortar. Rather, the blocks are fitted together without mortar, leaving the main work to lay the gravel footing and laying the bricks.

The basic design is the same for each block. The top and bottom plan views of a block are identical, and the front face is longer than the rear face. A pair of vertical holes is positioned at the front and rear corner portions. The top and bottom horizontal surfaces of a block are identical. The bottom plan view shows a block that is self-aligning and trapezoidal in shape.

They are easy to cut

If you are planning to build a retaining wall for your garden, it is essential to cut the masonry blocks precisely to fit the area. This will ensure that the walls will be flush with the garden’s topography. Make sure you subtract half an inch from the block height to make the joints flush. You can use a masonry blade to make the cuts. You should wear safety glasses while cutting stone and other materials because of the dust produced.

Wooden bricks are another option. The texture and grain of wood are very familiar and easy to handle. Those who are concerned about aesthetics will appreciate the fact that wood is made from a living source. Wood blends well with plants and the earth. In addition, it is light and easy to handle. It is easy to cut and install and requires minimal anchoring. Depending on your needs, you can choose between a traditional or a contemporary look.

Another option is to use a concrete masonry unit. These walls are relatively inexpensive to build and require less brick than a cavity wall. They are waterproof and may not require highly skilled masons. If you are building a brick retaining wall, you should take care to consider the drainage and water retention capabilities of the area. This is a great option for homes that have a small garden or a patio.

They can be built on a slope

A small brick retaining wall can be built on a slope to hold back the earth. It is usually 24 inches wide, with the depth depending on how high you want your wall to be. The base should be 4 inches deep and 18 inches wide. Be sure to leave space between blocks to allow for drainage. Once the wall is completed, it is time to finish landscaping the slope. If you have no previous experience building retaining walls, you should consult a professional landscape architect.

Typically, a retaining wall must hold back tons of water and soil. Even when it is constructed correctly, this wall can hold up to three feet of weight. And when winter comes, this wall can hold up to ninety-five tons of weight. Luckily, most retaining walls can be built with relatively small bricks. Once they are complete, you can begin landscaping. You can even have small brick retaining walls on steep slopes!

To build a small brick retaining wall on a slope, you should first determine the slope’s gradient. If the slope is steeper than one degree, you should use crushed gravel as your backfill. This will prevent tree roots from damaging the wall. Alternatively, you can install a perforated drainpipe behind the wall to channel water away. Once the wall is complete, you can add capstones for a more professional look. A capstone can be made from concrete pavers cut to fit the wall, which you can install with construction adhesive.

They can be built with a slight curve

For a more sophisticated appearance, small brick retaining walls can have a slight curve. The basic construction process involves a foundation of sand or gravel. Next, you lay bricks, one at a time, firmly pushing them down. Repeat this step with each block until the desired height and thickness is achieved. Small brick retaining walls with a slight curve are very popular in residential landscaping projects.

The radius chart shows the minimum radius for the base course. The top course can’t have a radius smaller than four feet (1.2 m). Next, mark the center of the curve with a stake. Line up the bricks to align with this mark. You can also use string line to mark the base course. Once you’ve determined the correct radius for your retaining wall, you can build it.

Once you have decided on a shape, backfill the area with a porous material. This material helps drain the water away and lessens the weight on the wall during heavy rains. Avoid backfilling the wall with dense soil, as it could put unnecessary pressure on the structure. To improve drainage, make sure the backfill is wider than the wall itself. Make sure the drainage backfill is slightly below the top of the wall, and then fill the rest with topsoil.

They require drainage

Small brick retaining walls require efficient drainage to prevent overflows. Besides installing drainage pipes, a landscaping contractor should also backfill the area behind the wall with gravel. If possible, you can also install perforated pipes on the inside of the wall to allow water to drain through it. Weep holes can also be installed on the inside of the wall. This will allow water to run off safely without compromising the structure of the wall.

Once the backfill is in place, the brick retaining wall should be placed. The backfill should be compacted. In addition to gravel, you should also use native soil to fill the space behind the wall. It is advisable to install a drainage pipe after the backfill to prevent groundwater from entering the structure and causing failure. Small brick retaining walls require drainage and foundation. Most municipalities require professional engineering for retaining walls.

When designing a small brick retaining wall, the drainage features are vital to the structure’s longevity. Weep holes, or small horizontal holes in the wall, allow water to escape from the wall and relieve the pressure. Additionally, a perforated drainage pipe is near the bottom of the wall, which contains many holes around the circumference to catch water trickling down the soil. This will help keep the wall from bending or collapsing under water pressure.
