How to Build a BBQ Island With Cinder Blocks

Cinder blocks are strong, heavy and fireproof building material units that can be stacked to make almost any structure desired. A cinder block barbecue island could be the centerpiece of a backyard patio and will provide a sturdy charcoal and preparation surface. By covering the exterior surface of the island with stone and slate, it will be weatherproof and eye-catching. All supplies needed, including the cinder blocks, can be found at building supply stores.

30 8-by-8-by-16-inch cement cinder blocks
10 pounds Portland cement
50 pounds of sand
Wheelbarrow
Trowel
16-inch square metal charcoal tray
16-inch square piece of slate

Instructions

- 1
  Carefully position three cinder blocks lengthwise on a level outdoor surface to create a 48-inch-long cinder block line.
- 2
  Position two cinder blocks lengthwise at a 45-degree angle to the ends of the block line, creating a U shape.
- 3
  Center one cinder block lengthwise in the center of the U, creating two connected U shapes.
- 4
  Mix five parts of sand with one part of cement in the wheelbarrow with the trowel. Add enough water to the mix to create a mortar that is the consistency of oatmeal. Add five layers of cinder blocks to the original shape, connecting the blocks with mortar.
- 5
  Use the trowel to apply the mortar to the outside vertical surfaces of the cinder blocks, and press the pea pebbles into the motor.
- 6
  Cover one open U-shaped top area of the completed barbecue with the charcoal tray. Cover the remaining U-shaped open area with the slate.
