Carport Anchoring & Installation Requirements
The correct anchoring system is required for structural stability and permitting compliance. Anchor type and quantity are determined by foundation conditions and engineered load requirements.
Permits: HD (Heavy-Duty) anchors are required when pulling a permit—engineered plans specify anchor type and quantity.
Included: Concrete anchors are included for qualifying slab installs. MHA and asphalt anchors are used when required by site conditions.
Included: Concrete anchors are included for qualifying slab installs. MHA and asphalt anchors are used when required by site conditions.
Concrete Anchors (Wedge / Expansion)
Surface: Concrete slab / footing- Standard for slabs and poured footings.
- Drilled through base rail; expansion locks under load.
- Common for residential and commercial slab installs.
Mobile Home Anchors (Auger)
Surface: Soil / dirt / gravel- Helical auger driven into ground.
- Connects directly to base rail.
- Often required for higher wind ratings.
Asphalt Anchors
Surface: Asphalt driveway- Designed for asphalt’s softer composition.
- Installed with drill and bonding sealant.
- Used when slab install is unavailable.
Rebar Stakes
Surface: Ground / temporary- Basic driven pin anchors.
- Lower resistance than augers.
- Upgrades recommended in wind zones.
Site Preparation: Level surface required (max slope variance ≈3″). Installers may decline unlevel or unstable sites to maintain structural integrity.
Installing on a Concrete Slab
- L-Brackets required when slab and frame are flush.
- Not required when slab lip extends ≥3″ around perimeter.
Anchor & Permit FAQs
- Anchor type is determined by foundation conditions.
- Engineered drawings specify quantity and placement.
- Wind warranty eligibility depends on correct installation.
Final anchor type and quantity are determined by engineered documentation based on structure dimensions, local load requirements, and site conditions.
