This small project is perfect for pointing out a few concrete construction fundamentals: the importance of the proper mix, stages of curing, and what the basic tools do to the curing concrete.

Step by step:

  • Excavate the area deep enough to allow a couple of inches of gravel plus the depth of the slab.
  • Spread two inches of gravel over the compacted earth. The gravel allows drainage under the concrete.
  • When mixing the concrete, measure the water. Don't add with a garden hose. Add 1 gallon of 'head' water per bag to the mixer before adding any Sakrete concrete mix. This consistency in water will help the slab cure consistently and maintain the integrity of the concrete.
  • After the concrete is poured, screed it into place and hand float the surface. This floating leaves the pores open on the surface allowing bleed water to escape as the concrete settles.
  • Let the concrete cure and bleed.
  • When the water evaporates, begin floating. Bull floating closes the surface of the concrete.
  • Now, edge, joint, broom, and leave it alone for 24 hours.
