How to Make a Backyard Brick BBQ Smoker

Dig a trench and pour concrete over it. The trench should be about 4 inches deep so that the concrete will be at least 4 inches thick. Lay rebar into the concrete before it dries completely to strengthen the foundation. Wait 24 to 48 hours for the concrete to dry.

Mix 3 parts sand with 1 part masonry cement in a wheelbarrow to make mortar. Mix these ingredients with a hoe; when they are completely mixed, add water according to the masonry cement package directions.

Transfer mortar to a palette. Use a trowel to spread a thin layer of mortar on the concrete foundation. Run the trowel across the mortar to make a "V" in the mortar.

Put mortar into the inside of your trowel. Spread the mortar onto the four sides of a brick. Place the brick where you want it on the concrete slab. Tap it into place with the trowel handle. Repeat for each brick until they are all where you want them. Stagger your bricks as you stack them for additional layers so that your walls will stay up.

Smooth the mortar between layers with a jointing tool.

Lay grill supports across the bricks and continue installing bricks. Place the grill on the support bolts.

Wait a week for the mortar to dry before using the barbecue for the first time.
