Howdy Nettie26,

 

I believe what your thinking about is a footer or foundation. Depending on your location you may need a permit to build such a structure, so it might be a good idea to make a call to your city building department.

With that said, here are some basic steps to building a footer.

 

 

POURING THE FOOTING FOR A BLOCK WALL

  • Every block wall–regardless of height or length–should be placed on a secure footing of poured concrete. A block barbecue grill or outdoor fireplace requires a large concrete pad as a footing.
  • The footing should always be poured deep enough so that the base is below the frost line.
  • Always make the footing at least twice as deep as the thickness of the wall and twice as wide. For example, if you are using 8" blocks, the footing should be at least 8" deep and about 16" wide. This footing will provide a 4" rim on each side of the block when laid.
  • The form for such footings can be made from rough 2x4s, held in place by wooden stakes driven into the ground about every 3' to 4'.
  • For a footing poured in an area where drainage is a problem, lay a drain line along the outer edge of the form. Allow for a drop of about 1" for each 20' of drain line. Backfill over the drain line with about 12" of crushed stone or gravel.
  • Before you pour the footing, be sure it will not prevent the natural run-off of water and will not divert the flow of water onto any neighboring property.
  • If gas, electric or water supply lines must pass through the footing, you must make an opening. Do this by nailing together four pieces of 2x8 and laying them in the proper position before the footing is poured. In many cases, a 4" piece of drain tile will serve the same purpose. Mark the depth and location of the utility opening on your foundation plan or with a stake so you can find it easily later on.
  • For large concrete foundation jobs that cannot be finished with one pouring, divide the forms into sections you can handle. Complete one before proceeding to the next.
  • Make sure your footing is level by placing a level across the footings about every 8'. Adjust the height of the 2x4s by raising or lowering the stakes to make the 2x4s level on each side at all points around the footing.
  • Fill the form to the top edge, then level the freshly poured concrete by pulling a 2x4 or some other straightedge along the top of the form (Fig. 3).
  • Work the straightedge back and forth–in a sawing motion–until the concrete is level. Fill in any low spots with additional concrete. Wipe away surplus concrete in the high spots.
  • Allow ample time for the concrete to dry fully. If the footing is to carry an extremely heavy load, drying may require up to three days.

 

Remember, if your not ready to take on such a project, it's ok to hire a professional.

 

Happy Building,

DO YOU NEED TO PUT DOWN ROCKS AND SAND TO PEVENT THEM FROM MOVING IN INDIANA PAVERS OR STEPPING STONES

Hi NETTIE26,

 

Paver Base is a mixture of sand and aggregate (stones) that should be applied at a rate of 4 to 6 inches deep with a 1 inch layer of leveling sand on top. 

 

This will increase the load bearing ability and stability of the patio or driveway.

Tamp the ground before adding the base and tamp the paver base before adding the sand.
