Pour the Concrete Slab
Using metal grill grates as a guide, determine the size and placement of the brick barbecue. If you desire a barbecue with walls thicker than one course of bricks, account for that now. Mark off the area and clear away all grass and debris from the site. Excavate the area to a depth of 8”. Use tamper to level and compact the ground. Add pea gravel to a height of 3” then compact and level with tamper.
Mix fast-drying cement according to manufacturer's directions. Pour on top of gravel until the hole is filled to ground level. Smooth and level the cement pad using a trowel. Allow cement to cure for 24-48 hours.
