Prepare the Site/Construct a Foundation
1. Dig a square, 6" (15cm) deep into the ground (remove grass).
2. Fill up to 4" (10cm) in the square with gravel and tamp firm.
3. Cover gravel with a sheet of 6 mil plastic.
4. Construct a wood frame using four planks of 2x4 (5cm x 10cm)
lumber.
5. Pour in concrete to fill in the hole and the frame giving a
total of 4" (8-10cm) thick concrete. Be sure surface is level.
Allow 3 - 5 hours for construction and a week for concrete curing time.
Note: Before beginning construction, check local building codes
regarding footings, location and other requirements.
