How To Build Steps From Retaining Wall Blocks

If you want to build a cinder block retaining wall with rebar, there are a few things you need:

-Cinder blocks


-A sledgehammer or hammer (depending on your preference)

-Some sort of measuring device (like a tape measure or ruler)

If you’ve never built a retaining wall before, it’s important to know that they’re not just built with cinder blocks—they’re also made out of concrete. So when building your retaining wall, make sure that you have enough concrete on hand to fill in between the cinder blocks. You’ll also want to make sure that the area where you’re building your wall has been leveled off and compacted down with extra dirt so that everything sits firmly in place.

If you’ve ever wondered how to build a cinder block retaining wall with rebar, you’re in luck. We’ve got all the information you need to get started.

Section : Building Your Steps Out of Retaining Wall Blocks. The first one is always tricky, but it gets easier once you get started. These blocks are great because they can be used to create straight walls or curved walls like we needed here! The treads were much easy because we didn’t have to cut them like we did for some of the riser blocks. Once you get all of your steps built, add more dirt behind them if necessary to fill in voids or stabilize them even more. You will also want to add dirt behind your retaining wall section as well before filling it with soil. Here is another view from the side so you can see all the work we put into this project! We are really happy with how it turned out, especially since this was our first time doing anything like this before! It makes such a difference in our yard’s appearance now that it is finished and looking great! This DIY project took us about 5 full days but could easily be done faster if you have more people helping out! The total cost for materials was under $500 which isn’t bad considering what an expensive project something similar would probably run from other contractors around here…especially since most don’t offer warranties on their work either (we do!!)

Measure The Area

Measure the area where you plan on building your steps, measuring the length and width with a tape measure. Next, measure the height of your retaining wall. This is important because it’s not always necessary to build steps that are taller than the retaining wall; in fact, many homeowners choose to build shorter steps that can be used as benches or seating areas rather than stairs.

Once you have these measurements recorded, it’s time to begin planning out what kind of materials you will need for your project.

Dig A Trench

In order to build steps from retaining wall blocks, you’ll need to dig a trench. The trench should be at least 6 inches deep, 2 inches wider than the block and at least 2 inches wider than your wall.

Set The Rebar Steel

Once you have the retaining wall blocks stacked, it’s time to install the rebar steel. The rebar will help increase the strength of your retaining wall and keep it from falling over under pressure. The first step is to cut a piece of rebar steel that will fit inside your block wall cavity, but not so long that it extends all the way out of either end.

Next, set this piece of rebar into place by using a hammer or mallet on either end until it fits snugly between two blocks without moving around too much. Once this is done, measure down and mark where each subsequent row will go with chalk so you know where to start when installing new rows later on (this will make more sense in just a moment).

Install The Rebar

Reinforcing the concrete is done by inserting rebar into the wet mortar before it hardens. The rebar will reinforce the concrete, making it more durable and stable.

Step 1: Mark where you want to insert the rebar by using a tape measure and marking each end at 6 inches from the end on both sides of your wall block wall. Make sure these marks are level so that everything else is level once you’re finished building your retaining wall steps.

Step 2: Drill holes into each corner of your retaining wall blocks using a hammer drill (or even just a regular drill), spacing them evenly along each side of each block so that they line up with where you’ve marked out for them with tape earlier on in this step (i.e., 6 inches from either end). You want to make sure there are at least 3 holes per block, but no more than 4 per block—you don’t want any stress points or weak spots forming when you place load on those areas later on down the road!

Install The Concrete Cap Block

Step 1: Use a level to ensure that the cap block is level.

Step 2: Dig a hole for the cap block using a shovel, ensuring it is deep enough so that the edge of your cap block lines up with the top of your retaining wall blocks.

Step 3: Tap in place using a mallet or hammer and metal rod until you have it flush with surface of your retaining wall blocks.

Step 4: Fill in dirt around perimeter of concrete cap block until it’s about flush with surrounding ground surface (don’t worry about getting dirt inside of cutout pattern).

Fill With Crushed Gravel

Fill in the trench with crushed gravel, making sure to use a shovel or rake to level it out and remove excess material. Sweep off any loose debris with a broom.

Replace The Topsoil And Grass

Once you’ve constructed the steps and installed them, you’ll want to replace the topsoil and grass that were removed during construction. As long as you’ve left the retaining wall block intact, this process is relatively simple. Simply remove the dirt from around the blocks with a shovel and replace it with new topsoil. Then plant grass seed over this new soil (or seed).

Building a cinder block retaining wall can be done yourself and it is not that difficult.

Building a retaining wall can be done yourself and it is not that difficult. It can be a fun project to do with the kids and at the end of the day you will have your own retaining wall that you can use for storage or to create an area for gardening.

Retaining walls are used in many different places such as gardens, walkways, driveways etcetera. If you follow the steps correctly it will come out looking great!


The final step is to fill the joints between each stone with sand or mortar. This will prevent excess moisture from seeping into the stones. Once your new steps are built, set up a watering schedule that includes both irrigation and deep watering of your retaining wall (at least once a month).
