How To Stack Retaining Wall Bricks

A retaining wall can be a great way to create a barrier on your property and make room for additional landscaping. It’s also a fairly simple project for someone with the right tools, so long as you’re working on an appropriate slope. This article will walk you through the steps of creating your own retaining wall from scratch. If you already have an existing retaining wall, there may be other considerations that should be taken into account when determining if this process is right for you.

Get the Right Materials

The first step to stacking your retaining wall bricks is to make sure you have the right materials. You’ll want to buy bricks that are the same size and color, as well as bricks that are made of the same material. The best way to ensure this is by buying them all from one place, so look for brick dealers with a large selection of high-quality products. This can be done online or even at your local hardware store—just make sure you’re getting enough bricks so that each course will be stable and secure!

Dig a Slope

The first step of building your retaining wall is to dig a slope. You want the top of this slope to be 1/3 the height of your retaining wall.

If you are building a tall retaining wall (more than 4 feet), dig a trench instead of digging shallow slopes on both sides of the trench. This will give you more stability and make it easier for you to line up bricks later in the process. When digging trenches, use a level every few inches while digging so that they’re straight and even as possible when finished.

Dig a Trench

After you’ve stacked the retaining wall bricks, it’s time to dig a trench. Before digging, make sure that your trench is deep enough to hold them. You also want it wide enough and straight enough (no curves). The bottom of the trench should be level with or slightly below ground level so water does not pool in it after heavy rainstorms or snow melts. If you have an existing retaining wall on either side of where you’re digging, consult with your local building department about how high up from these walls they recommend placing this new one—local requirements vary from place to place and jurisdiction-to-jurisdiction.

Lay a Base

Now you can finally start laying your bricks. The first course should be laid on a level, solid base that’s at least 3 inches thick and quite compacted in order to prevent any shifting or cracking as the walls get higher. This base should also have been given time to cure before you begin your project, so that it won’t absorb too much moisture from the wet mortar mix and cause problems later on (we recommend at least 24 hours).

Next, lay down your second course of bricks in a staggered pattern. Start by placing one brick lengthwise along one edge of the baseboard, then place another brick diagonally across from it so they form an “X” shape when viewed from above or below. Repeat this process until all four sides are filled with staggered rows of bricks — then fill in any gaps with additional bricks as needed!

Once all four sides have been completed, stack up two more layers of staggered rows: first place two rows vertically against each other rather than horizontally like before; then place two more rows horizontally against each other (repeat this process until finished). Make sure they fit together snugly without gaps between them; if there are some large spaces between adjacent courses where not enough mortar was applied during construction time – fill them up now using additional mortar before applying cement grout later down the line when everything is dry again!

Lay the First Course of Bricks

The first step is to lay the first course of bricks, making sure they are level. There are several ways you can do this:

  • Use a level (also called a spirit level) to ensure that each brick is exactly horizontal.
  • Use a laser level, which emits a beam of light across the wall, showing where it needs to be leveled.
  • Use water levels, which allow you to find out if one end of your brickwork is higher than another by placing it in water and seeing where the liquid reaches on each side.

Place the Second Course of Bricks

  • Make sure to use a level to ensure that each row is straight and level with the previous course.
  • Ensure that every brick sits firmly on top of its neighbors so they are not too close together. This will make it easier to stack them in the next step.

Place the Final Courses of Bricks

The final course of bricks should be laid on top of the first course, making sure that they are level and straight. Make sure that the wall is at the desired height before you begin this step. The last brick will need to be cut so that it fits snugly between two other bricks in order for everything to look uniform and professional.

If you have a large enough yard, you may want to build a retaining wall.

If you have a large enough yard, you may want to build a retaining wall. A retaining wall is generally made of brick, stone or concrete and can be used for borders around flower beds or ponds. You should be comfortable using tools such as shovels and rakes.


That’s all there is to it. That wasn’t so hard, was it? You’ve now added an attractive structure to your yard and if you do the job right, it will last for a long time. Your friends and neighbors may even ask you to build them one too!
