Site Prep & Concrete Specs
Get these done before install day and the crew can get your building up without delays.
Site prep checklist
Call 811 before you dig
It's free. They mark underground water, gas and electric lines so nobody hits one. Call before you grade, pour or set anchors.
Level the site, within 2 inches
The building needs a level spot. Grading may be needed first. An unlevel site can mean delays, labor charges, or a return trip fee.
Clear the area
Move vehicles, trailers and debris. Leave 2 feet of clearance on all sides of the building.
Payment is due when the crew arrives
Payment is due before work starts. Cash, cashier's check, money order, or card (card fee applies).
Tell us about site rules
If your site has safety rules or required training, tell us when you buy so we can plan for it.
Plan for install day
A standard carport install usually takes 4 to 6 hours. Larger or enclosed buildings take longer.
Anchoring
- Concrete pad: concrete anchors.
- Bare ground or gravel: ground anchors.
- Asphalt: asphalt anchors.
Concrete specs
Concrete requirements depend on your building and manufacturer. We'll send you the exact specs for your building before you pour.
- Buildings are not sealed to the concrete. Ask your concrete contractor about sloping the edges so water runs off.
- Existing concrete, piers or retaining walls? Send us photos first.
In Deschutes County, the county's design criteria list the frost depth for footings. See the snow, wind and frost section of our permit guide, and don't pour until you know your building size and snow load.
