Neatly trim sides and bottoms of trenches and remove any loose dirt prior to placing concrete.

2.  Grade beams installed per plan

8.  Make sure slab is screeded evenly and tamped with 3/8-inch mortar at the surface

9.  When grading for the slab area, be sure all footings, including interior footings, are exposed and cleaned of all loose dirt. Keep the polyethylene vapor barrier off all footings. Check the mil size of the polyethylene vapor barrier. Make sure outside footings are 3 inches away from the forms. Check the soils report to see if pre-saturation is required on any pads.

Make sure steel is hung properly and cleaned prior to the local agency’s (county-city) footing inspection. Verify that all bars have 20 times the diameter or Class “B” splices (minimum) and that all horizontal splices are staggered per UBC Sec. 2612-P.

Next, sand or gravel fill over the polyethylene vapor barrier, if required. Check sand for proper coverage (1 or 2 inches) and for proper moisture content. Some areas of the country require termite spraying under the polyethylene vapor barrier. String-line all slab areas for 4-inch nominal slab. Always wet sand prior to pour, especially if it is a hot day. Make sure interior trenches are wheel-rolled and filled with nonexpansive native soil or imported sand. Make sure plumbing trade contractor’s trenches have double-wire mesh, if required. Make sure wire mesh is per contract and soils report. Check electrical conduit and floor boxes. Make sure all plumbing and electrical wiring is tied down so that it cannot move or float during the pour. Schedule a preslab inspection
