How To Build A Wall With Cinder Blocks

A cinder block wall, built from concrete masonry units (CMUs), is just as strong if not stronger than a poured concrete wall. It’s typically used for foundations, retaining walls, and quite often for the exterior walls of buildings. Cinder blocks are often referred to as CMU but really CMU stands for concrete masonry unit, which is more inclusive of other types of blocks such as clay bricks and glass blocks. For this article we’re going to focus on building a cinder block wall.

Step 1: Gather Materials.

  • Buy Cinder Blocks. Cinder blocks are the foundation of any good wall, so you’ll need to pick up a few hundred of them before you can begin construction. Don’t worry about the color—they will all be painted in the end anyway
  • Buy Mortar. Mortar is a special substance that goes between the cinder blocks and holds them together when they are stacked on top of each other, forming walls with solid surface areas for your home or business building project.
  • Buy Gravel As Well As A Tarp To Cover The Ground Around Your Site Of Construction For Protection From Water Damage That Can Occur If There Is Rainfall While You Are Building Your Wall With Cinder Blocks And Mortar Or Other Materials That Could Be Exposed To Moisture Such As Concrete Or Wood Flooring Which Can Lead To Warping And Leakage Problems In Some Cases (Such As If You Use PVC Pipes Instead Of Metal Ones).

Step 2: Build the Foundation.

Your foundation must be level, strong enough to support the wall, placed on a solid floor and free of debris. If there are obstructions or cracks in the foundation, they should be repaired before you begin building your wall.

The next step is to install the wall blocks that will form the base of your cinder block wall. First decide how tall you want your cinder block wall to be by measuring from one end of your site to another until it meets up with itself. Then mark this height on both ends of where you want to place this section of cinder blocks; these marks will let you know where all other sections of cinder blocks will go during later steps so they can fit together perfectly

Step 3: Add Gravel

  • Add Gravel.

The gravel is important to your wall’s structure, but it also has many other benefits. It acts as a drainage layer that will prevent water from pooling at the bottom of your wall, and it absorbs vibration from any earthquake or aftershocks, which could cause cracks in the cinder blocks. Gravel is also an excellent insulator (which means it keeps heat inside) and fire retardant (which means that your home is safer). If you’re building a sound barrier, then gravel makes an ideal choice because it absorbs noise well.

Step 4: Lay the Cinder Blocks.

Step 4: Lay the Cinder Blocks.

Laying your first course of cinder blocks is just like laying any other wall, but with some slight variations. Follow these steps to make sure you’re constructing a perfectly straight and level wall:

  • Start with a corner block.
  • Lay one row of cinder blocks in each direction from there, making sure to keep mortar joints running vertically (vertical mortar joints will be easier to repair if necessary).
  • Level each row as you go by using a plumb bob (an object that hangs down on string) and leveling tools (plumb lines), which you can buy at any hardware store or home improvement store.

Step 5: Add Bond Beam Block (optional)

If you are using a bond beam, make sure that it is level with the top of the cinder blocks.

To ensure your bond beam will be flush with the top of your cinder block wall, use a level and ruler to mark where your blocks should be placed. To prevent shifting or cracking when stacking concrete, use spacers between each layer and align them so they run perpendicular to each other across the wall. If possible, attach vertical supports from inside one row of blocks to another (known as a corner tie) using bolts and nuts prior to placing any concrete in between them—this will provide extra strength when installing drywall later on since it will not fall down due to uneven surface pressure during construction work taking place nearby

Layering cinder blocks requires a lot of noise—we recommend wearing hearing protection if possible because loud noises can cause permanent damage over time (or worse). If this isn’t feasible for whatever reason then at least try not talking too loudly while working on your build project so as not distract others nearby who might also need their hearing protected from loud sounds such as jackhammers or saws being operated directly overhead (which would happen if you were building an outdoor patio).

Step 6: Mortar the Bedding Throughout the Wall.

Once you have spread the mortar on all four sides of each cinder block, use a mason’s trowel to press it into place. Make sure that the mortar is level with your surface. Now it’s time to lay out your wall, so that it looks straight and level before adding your second course of cinder blocks. For this step, use a 4-foot level and a mason’s line (or carpenter’s string) as guides for laying out your walls in a straight line.

Step 7: Pour Concrete for the Footer.

  • You are now ready to pour concrete for the footer. Place a layer of cinder blocks on top of the prepared base, leaving space at each corner for mortar.
  • Lay your first row of cinder blocks in a pyramid style and then use additional blocks to create your desired length. Leave some space at each end for grout between the last block and the side walls. This will make it easier when you have to fill holes later on with grout or cement mix.

Step 8: Finish with a Capstone.

Once your wall is complete, it’s time to add a capstone. Capstones are usually the most decorative block in a wall and they’re often the largest and heaviest block as well. They can be any shape or size you want, but they should also be at least as wide as an average person’s shoulders to provide adequate stability on top of your new structure.

The importance of this part cannot be overstated: without a good capstone at the top of your structure (like with any structure), there would be nothing holding it up. Your entire masterpiece could come tumbling down if there were no support at all on top of those cinder blocks—especially if you plan on building anything else below it

Building a cinder block wall isn’t as difficult as it might seem, as long as you follow all safety precautions and take your time to get it right

Building a cinder block wall isn’t as difficult as it might seem, as long as you follow all safety precautions and take your time to get it right. Here are some tips:

  • Always wear the proper safety gear when working on any project. This includes goggles to protect your eyes and ear protection in case of flying debris or loud noises.
  • Always read through instructions carefully before beginning any project, especially if you’re new to DIY projects such as this one! It’s important that you know what tools and materials you’ll need for this job before getting started so that you don’t run into any surprises later on down the line (like running out of something halfway through).
  • Practice makes perfect—and there’s no better way to improve at something than by doing it over again until things start clicking. Once finished building your cinder block wall, consider taking another crack at making another one; but this time try coming up with an improvement upon what worked well last time around, like using different methods for laying each row of blocks down where gaps between them aren’t visible from sight lines closer up (which can happen more easily when working alone).

Final Words

We hope you found our advice on how to build a cinder block wall helpful.
