Step 3Lay first course of cinder blocks
first thing to do is to use some cement epoxy to embed the rebar securely into the concrete foundation. drill the hole and epoxy it in. next, create a dry well for the drain water to go. if you can just connect the drain for the sink to a house drain pipe, this isnt necessary. dig a deep hole that is a bit larger than the barrel that you have. our barrel was gotten for free from a friend who works at a coca cola plant, and once had sprite syrup in it. drill many holes into the barrel, and put the drain pipes through the lid. the bottom of the barrel isnt necessary. put the barrel into the hole and fill around it with course gravel. mix up the mortar/mud and lay the first layer of bricks. they should be as close to perfectly level as possible. fill around the drain pipes with cement. the barrel and drain pipes will be buried, since the area behind the barbecue will be backfilled with dirt.
