Concrete Pad Construction
Use the following procedure to construct the concrete pad:
1. Build a wood form for the concrete pad using 2 x 6 framing lumber as shown in
.
2. Locate the PMF as shown in the construction diagram (see
). When installed, the
top surface of the PMF must be flush and level with the top of the concrete pad.
3. Place reinforcing material inside the form but outside of the PMF.
4. Verify that the PMF and form are level. Depending on the landscaping requirements, the
top surface of the concrete pad may be 0 to 3 inches (0 to 7.6 cm) above the final grade. The
weld nuts are covered with plugs which must be left in place until the enclosure is mounted.
5. Pour the concrete to form the pad but do
not
pour concrete into the center area of the PMF.
6. Remove the top framing and the temporary support wires when the concrete is ready to be finished.
7. Allow concrete to cure before proceeding with the installation.
Note:
Use temporary top framing to keep the top surface of the PMF flush and level with
the top of the concrete pad (see
Note:
Allow some concrete to flow under the flanges on the bottom of the PMF so the
PMF will be locked in place when the concrete hardens. However, do not allow concrete to
fill the center of the PMF. If necessary, partially fill the center of the PMF with sand or
gravel to prevent an inflow of concrete.
