Installation Instructions

SITE PREPARATION FOR CARPORTS, SHELTERS, STOR-PORTS & BUILDINGS

The Versatube frame is designed to be placed on a foundation that is level side to side and sloped about 1/8” per foot

back to front. (The slope will allow water that may gather in roof horizontal ribs to run to one end. The water should flow

over the center seam in your roof panels and not into the seam. IF YOU ARE BUILDING A STOR-PORT, water that hits

the concrete slab must also run off the slab, away from the storage end of your stor-port.) That foundation can be: pre-

pared ground (leveled and re-compacted), a concrete footing, or a concrete mono slab with built-in footing. It is

important that you create one of these conditions prior to your carport, stor-port, shelter or building installation. We

recommend that you check with your local building official prior to starting your project to find out what is acceptable for

foundations and anchoring in your county. If you extend the carport site about 3 or 4 feet on all sides, it will make it easier

to position ladders for sheet metal installation.

SLAB WITH FOOTING OR FOOTINGS ALONE

If you will be pouring a slab for your carport, the slab should be 4” thick and have a footing down both sides. Buildings

should have footings under the back and front walls. Stor-ports should have footings under the front and back walls of the

storage area of the stor-port. 3 sided shelters should have footings under the side and back walls. The footing should be

12” x 12” with a 45° blend between the slab and the footing. The slab should have a back to front slope of about 1/8” per

foot. One run of #5 rebar mid-depth is recommended in the footing. Check with your local building official for details and

requirements in your county. Some counties require the footing to extend down below the frost line. The concrete should

be 2500 to 3000 PSI.

The outside dimensions of the slab should be at least 3” larger than your frame dimensions. Example: if you have a 20’ x

27’ frame, the slab should be at least 20’-3” x 27’-3” minimum. This will allow the center of your anchor bolts to be 3” from

the edge of the slab.

FOOTINGS: Footings alone should be 12” wide and 12” deep and can be positioned so the base rails are centered in the

footing if you will be using wedge anchor bolts to anchor the base rails. The outside dimension of the footing will be the

carport width plus 9”. The basic carport 5’ On Center frame is 20’ long. The 4 1/2’ On Center frame is 18’ long and the 4’

On Center frame is 20’-2”. Footings should be 3” longer than your frame. Footings should also slope 1/8” per foot front to

back or back to front to allow water that might gather in horizontal ribs to flow over roof lap joints and off the roof.
