Start laying your first row of cinder blocks. This step is crucial, as it sets the tone for the entire wall.
- Use a Stringline: Stretch a stringline between two stakes placed at either end of the trench. This will help you maintain a straight line for your blocks.
- Lay the Blocks: Start placing the first block at one end of the trench. Ensure the ends are aligned with the stringline.
- Check with a Level: Use a level to ensure the block is even. Adjust it by adding or removing gravel as needed.
- Place Additional Blocks: Continue laying the blocks side by side, checking the level after each placement.
Step 4: Mortar the Joints
Once your first row is in place, it’s time to fill the joints with mortar.
- Mix the Mortar: Follow the instructions on your concrete mix package to create a thick, workable mixture.
- Apply Mortar: Use a trowel to apply mortar between the blocks, ensuring the joints are filled but not overflowing.
Step 5: Add Additional Rows
With your first row secure, you can begin adding additional rows.
- Stagger the Joints: For structural integrity, offset the blocks so the joints of the second row do not line up with those of the first row.
- Repeat Mortaring: Keep applying mortar as you build each row until you reach your desired height.
Step 6: Cap the Wall
Once you achieve the required height, consider capping your wall for a finished look.
- Select Capstones: Choose cinder block capstones to place on top; these provide a clean finish and greater stability.
- Use Mortar: Mortar the capstones in place as you did with the lower blocks.
Step 7: Clean Up and Final Touches
After finishing your wall, it’s essential to clean up and perform some final touches.
- Remove Excess Mortar: Use a damp sponge to wipe off any excess mortar from the blocks’ surface while it’s still wet.
- Let it Cure: Allow the mortar to cure for at least 24 hours before applying any pressure or weight to the wall.
- Add Landscape Fabric: If you plan to add soil or plants behind the wall, consider placing landscape fabric to prevent weeds.
