Just looking for a little information and assistance perhaps. We are
presently beginning the process of building a small garage in Nova Scotia.
We will be pouring the slab next week. My query is whether it is
advisable to start the construction with a sill of pressure treated lumber
(2x4) anchor bolted to the slab with a membrane that is used to start a
roof shingling under it and then nail the wall to that sill. We would
then let the sheathing project beyond the plate, the sill and over the
slab by 2". Any ideas, suggestions or criticism. I worry about water
and/or snow getting under the sill.Thanks in advance


I would consider putting a row of 4" tall concrete block around for the base
of the wall and them build up from that. It will keep the wall sheeting a
few inches off the floor, and you can wash out the shop with a garden hose
if you like without soaking the wall. If nothing else use the PT bottom
plate, but seal it to the concrete with a good polyurethane caulk when you
set it in place.
If I were to build a garage again I would skip the floating slab, put down a
foundation wall below the frost line and build from that. My slab was poured
to code, but in the 20 years since, the outer edges are sinking from the
weight of the building.
