There is a small gap between my base plate and my concrete slab. With weight, the base plate obviously bends and contacts the slab. How much of a problem is this gap, and what should I do moving forward?


For context, slab is 12' x 24'. I poured it myself, but as this was my first concrete project, obviously I did a poor job of leveling around the anchor bolts. The structure is a simple rectangle. The walls will be 7-10' tall. Shed style roof. Metal roofing. I live in an area with little-to-no snowfall.

2 points before that problem, treated or not we never put wood to concrete with out something between, poly, tar paper, or sill gasket.

You sill length should be short when you subtract 2 thickness of wall sheeting.

If you are doing 1/2 in sheeting the end plate 11'11" and side would 23' 11"

Unless the sheeting will be the siding then the frame is the same size.

2 ways to deal with this

1. Add an anchor bolt 2 feet from those bolts on both side of the bolts and force it down and then cut each stud to fit the sag so the top is level

2. remove that and lay down a line of mortar, put the plate back down tight on sheet poly and tap the plate down so it settles fairly level while it is still wet.
