1). The slab must be square and level. If the concrete is out of level (greater than ¼" in 10') it causes
expensive shimming or cutting of framing. If corrections are not made during framing, the lines
(where the wall meets the ceiling) may be noticeably out of level. If the slab is not square this will
cause serious problems with your shed.
2). Your slab must be the same stated size of your new shed. For example, if you purchase a
10' x 12' shed, your slab must be 10'x 12'.
3). Anchors, ½" x 8" J-Bolt type anchors ( or equivalent ) should be set in the concrete around the entire
perimeter. Anchors should be 12" from the corners and 32" on center thereafter toward the center of the wall on the slab, except where
the door goes. This way there will not be an anchor where a wall stud should be if the
framing is 16" on center. The J-Bolts should project approximately, 2 ½" above the slab
surface and approximately, 1 3/4" in, from the edge of the slab.
4). For best results, make sure blocks, wire mesh and reinforcement bars are used in the slab to help prevent cracking.
5). The finished surface of your slabs must be a minimum of 5" above the grade.
