Laying the Foundation
A solid foundation is critical. Excavate a trench to the appropriate depth, below the frost line if necessary, to prevent shifting during freeze-thaw cycles. Pour a concrete footing to create a stable base for your brick frame. Give the concrete time to cure fully before proceeding—this usually takes several days.
- Footings: Dig a trench for the footing, ensuring it’s level and deep enough to go below the frost line (if applicable to your climate).
- Concrete: Mix and pour concrete into the trench to create a stable footing.
- Curing: Allow the concrete footing to cure completely, which may take several days.
Building the Frame
- First Layer: Lay the first layer of bricks on the footing, using a layer of mortar between the footing and bricks. Check for level and make adjustments as needed.
- Subsequent Layers: Continue building up the layers of bricks, applying mortar between each brick. Stagger the bricks so the joints don’t line up; this increases the structure’s strength.
- Reinforcement: Every few layers, add a horizontal layer of metal mesh or rebar to reinforce the structure.
- Corners and Edges: Pay special attention to corners and edges, ensuring they’re square and level.
- Openings: Leave spaces for your grill, storage, and any other features you plan to include. You can use wood to create temporary frames that help keep the shape while you lay the bricks around them.
- Leveling: Regularly check for level and plumb as you build up.
Finishing Up
- Mortar Joints: Once the brick frame is up, strike the mortar joints with a jointer for a smooth, finished look.
- Curing: Allow the brickwork to cure. The time needed can vary depending on the weather and the mortar you’ve used.
- Inspection: Inspect the structure thoroughly for any gaps in the mortar and fill them as needed.
Adding Countertops and Inserts
- Countertops: Once the frame is built and cured, you can add a countertop by laying a solid slab of stone, tile, or another suitable material on top.
- Inserts: Install your grill and any other appliances or accessories into the spaces you’ve left for them.
Safety Check
- Stability: Make sure everything is stable and secure.
- Clearance: Check that you have the necessary clearance for the grill and any other heat sources from combustible materials.
Tips:
- Always wear safety gear like gloves and goggles when working with bricks and mortar.
- Keep the mortar at the right consistency – it should be like peanut butter, not too dry and not too runny.
- Clean any excess mortar off the bricks as you go to keep a clean look.
- If you’re not experienced with masonry work, consider practicing on a smaller project first.
Building an outdoor kitchen frame with bricks can be a rewarding project that adds value and enjoyment to your home. Take your time with the process to ensure a safe and sturdy result.
