How Many Anchors Do You Need For Your Car Shelter?
All car shelters come with standard U-anchors, which are the basic anchors included with purchase.
However, these anchors are often insufficient to withstand the harsh weather conditions of Québec.
That’s why we recommend considering a few additional options to reinforce the stability of your shelter.
OPTION 1 – Permanent Anchors
These anchors are fixed directly into the ground and provide strong, durable stability.
| Shelter Size | Permanent Anchors | Number of Sections (± 4–5 ft each) | Layout |
|---|---|---|---|
| 8' | 4 | 2 sections | 2 anchors per side |
| 12' and 15' | 4 | 3 sections | 2 anchors per side |
| 16' | 4 | 4 sections | 2 anchors per side |
| 20' | 4 | 4 or 5 sections | 2 anchors per side |
| 24' and 25' | 6 | 5 or 6 sections | 2 anchors per side |
| 28' and 30' | 6 | 6 or 7 sections | 3 anchors per side |
| 32' and 35' | 6 | 7 or 8 sections | 3 anchors per side |
| 36' | 8 | 9 sections | 4 anchors per side |
| 40' | 8 | 8 or 10 sections | 4 anchors per side |
OPTION 2 – Temporary Anchors (Concrete Blocks)
You can purchase these at most hardware stores or local suppliers.
Trévi recommends using 6 blocks per section of 4 to 5 feet, which equals 3 blocks on each side.
| Shelter Size | Concrete Blocks | Number of Sections (± 4–5 ft each) | Layout |
|---|---|---|---|
| 8' | 12 | 2 sections | 3 blocks per side × 2 sections |
| 12' and 15' | 18 | 3 sections | 3 blocks per side × 3 sections |
| 16' | 24 | 4 sections | 3 blocks per side × 4 sections |
| 20' | 30 | 4 or 5 sections | 3 blocks per side × 5 sections |
| 24' and 25' | 36 | 5 or 6 sections | 3 blocks per side × 6 sections |
| 28' and 30' | 42 | 6 or 7 sections | 3 blocks per side × 7 sections |
| 32' and 35' | 48 | 7 or 8 sections | 3 blocks per side × 8 sections |
| 36' | 54 | 9 sections | 3 blocks per side × 9 sections |
| 40' | 60 | 8 or10 sections | 3 blocks per side × 10 sections |
OPTION 3 – Wind Straps
Easy installation
They are installed horizontally, about 3–4 feet from the ground, and are not dependent on the shelter’s height.
Simply attach two straps per shelter, one on each end.
