If the ground is frozen, it cannot be dug out by hand.
Also, extreme cold can affect the curing process ofthe mortar.
Permits and Codes
Free-standing concrete block walls may require permitting.
In some cases, alternating columns of cinder blocks may need vertical rebar or a ladder mesh reinforcement.
You may also need to run horizontal rebar the length of the wall.
Discuss your intended concrete block wall with your local permitting department for information on rebar or reinforcement requirements.
Safety Considerations
Working with masonry materials is labor-intensive, so take frequent breaks and stay hydrated.
Keep your back straight and use your legs when lifting.
Wear heavy-duty gloves when handling concrete blocks.
Wear breathing protection when pouring mortar or concrete or for any other activity that creates dust.
Pour the Concrete
Fill the trench with concrete until it is just below the frost level.
Wait two or three days for the concrete to cure.
Snap two more lines: one on each side of the intended bottom row of blocks.
Test the mortar with the trowel by picking up some mortar and then holding the trowel to the side.
Ideal consistency is achieved if most of the mortar remains on the trowel.
Lay the Mortar Base
Lightly moisten the footing with thegarden hoseand sprayer.
This keeps them clean until you use them next.
Butter each side of the closure block and set it straight down.
Fill in any extra space between joints with mortar.
Do this while the mortar is still wet.
You’ll know when to do this if the mortar is stiff enough to imprint your finger.
load the cap blocks, alternating across joints.
Scrape excess mortar and fire off the jointer along the joints again.
