Constructing a block garage will give you a much stronger and much more durable type of garage in comparison to garages that are built from wood or from steel. They are capable of holding beams up much more easily, and they also tend to be resistant to rodents and insects. They rarely ever fall down or cause leaks over time in poor weather. Because concrete block garages are so thick, the garage will naturally be more sound proof in comparison to other types of garage. Man power is required when it comes to constructing such a garage, and the costs can be considerably larger if you do not watch your budget, but in general the cons are far outweighed by the pros.
Step #1: Layout Area for Garage
The first thing that you are going to want to do is to lay out the area where you are going to place your garage using your stakes. Place stakes in the four corners, digging all of the dirt in between these stakes so that there is a six inch deep area the size of your garage design. Now you should place 2 x 6 form boards all around the entire perimeter, marking off where your block garage is going to go.
Step #2: Nail Boards
Next, you should nail boards at each of the corners, placing stakes behind these boards at every third foot in order to create extra support. You should nail the stakes to each of the form boards using double headed nails so that when you are completely finished, the nails will be easily capable of being removed from the form boards.
Step #3: Dig Out Footings
Now what you are going to want to do is to dig your footings out at 1 foot in width and 18 inches in depth around the entire perimeter. A footing is defined as the slab's structural part, baring the entire weight load of the structure that will be created above.
Step #4: Insert Rebar
Now you should place ½ inch rebar horizontally along the entire bottom of the footings. The rebar should be kept at least 3 inches apart from the earth using a 3" x 3" dobey block at every 3 feet underneath all of the rebar. The rebar is a structural rod made from steel that is used to add strength to concrete and it is capable of being purchased at any hardware store, and dobey blocks are small blocks of concrete that have tie wire built right into them.
Step #5: Finishing Up
Run the rebar along the footings' tops, then attach rebar rods vertically around the footings as well with 4 inches of clearance. Tie them all into the top and the bottom using tie wires. Pour sand into the garage slap area to create a vapor barrier. The vapor barrier helps eliminate discoloration caused by mildew. Then, rake the sand flat and moisten it lightly before laying the concrete down. Pour the concrete into the footings, allowing it to flow over the entire slab foundation. Once it has hardened completely, you can begin the building of your block garage.
