Bob's Bunker Page 58

This photo shows the grading of the gravel fill which was used as a filler between the roof deck of the bunker and the concrete driveway and the patio. On average, 12" of gravel sit between the EPDM waterproofing system and the underside of the driveway and patio.

The 6" diameter PVC pipes you see embeded into the gravel fill, will provide post holes for 4"x4" cedar fence posts that will support a cedar fence along the north edge of the driveway apron (on the left of the wood forms) which will seperate the "Green Roof" grassy area ( on the right side of the wood forms) from the driveway apron.

At the top of the photo you can see the footings for the garage walls which are covered by the EPDM rubber waterproofing membrane.
