2.5.7.6. Waterproof Membrane. Place the 2- by 8-foot composite panels on<br />
<strong>to</strong>p of the roof supports and connect them using the <strong>to</strong>ggle connec<strong>to</strong>rs. Drive<br />
the <strong>to</strong>ggle connec<strong>to</strong>rs in as far as possible, cut them flush, then place the waterproof<br />
membrane on <strong>to</strong>p of the roof as illustrated in Figure 2.28.<br />

2.5.7.7. Overhead Cover. Constructing overhead cover is the last step. Begin<br />
by aligning sections of containers along the roof as shown in Figure 2.29.<br />
Ensure the flaps at the bot<strong>to</strong>m of the units are folded in. Fill the bays as previously<br />
described and lightly compact. After all of the bays are filled, place<br />
approximately 2 feet of fill material in the center of the roof <strong>to</strong> complete<br />
overhead cover (Figure 2.30). Once completed, check <strong>to</strong> make sure there is<br />
no excessive deflection of the roof (up <strong>to</strong> 1½ inches is acceptable). Also,<br />
make sure the roof supports are centered on the sidewalls and sheet pilings<br />
are fully supported by the roof supports. Lastly, check <strong>to</strong> make sure all walls<br />
are straight and that there is no excessive settlement of the walls.
