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 (not supplied) 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.
