ANCHORING TO GROUND WITH CONCRETE PIERS

DIGGING HOLES FOR CONCRETE

Mark the locations of the rails and the anchor holes on the ground. Move the base rails to one side and dig holes at each

anchor point for concrete. You may want to rent a gas-powered post hole digger with an 8” or 12” diameter auger for this

job.

HOLE SIZE:

Counties with 70 or 80 mph Exposure C wind: Use a 12” diameter hole 14” deep or a 8” diameter hole 18” deep.

Counties with 90 mph Exposure C wind: Use a 12” diameter hole 18” deep or an 8” diameter hole 24” deep for 12’ to 20’

wide carports. For 24’ and 30’ wide carports, use a 12” diameter hole 21” deep or a 8” diameter hole 30” deep.

ANCHORING

Move the base rails back into position over the holes. Re-measure to make sure the rails are in the proper location (see

layout on page 6).

Now drop or drive a Versatube 30” re-bar ground anchor or a 1/2” x 36” threaded rod with a flat washer and nut at the

top into each anchor hole. A 24” rod could also be used. Threaded rods are normally 3’ long from your building center.

Mix up concrete and pour into holes up to ground level. You may want to rent a mixer for this job. Before the concrete

sets, re-check all your dimensions to make sure the frame is square and has the proper width.

Let the concrete cure overnight before installing the Roof/Wall assemblies.

NOTE: If it is necessary to assemble and anchor the carport all in one work session,

you can anchor the carport after it is complete. If you assemble the frame and install

sheet metal before anchoring the base rails, it is important to have the site prepared

and level. This will allow you to get the frame square and the sheet metal properly

aligned with the frame.
