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' 4 3 sections 2 anchors per side
16' 4 4 sections 2 anchors per side
20' 4 5 sections 2 anchors per side
24' 4 6 sections 2 anchors per side
28' 6 7 sections 3 anchors per side
32' 6 8 sections 3 anchors per side
36' 8 9 sections 4 anchors per side
40' 8 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' 18 3 sections 3 blocks per side × 3 sections
16' 24 4 sections 3 blocks per side × 4 sections
20' 30 5 sections 3 blocks per side × 5 sections
24' 36 6 sections 3 blocks per side × 6 sections
28' 42 7 sections 3 blocks per side × 7 sections
32' 48 8 sections 3 blocks per side × 8 sections
36' 54 9 sections 3 blocks per side × 9 sections
40' 60 10 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 side.

  • 22’ → for shelters 10’6’’ to 12’ wide (2 straps required)

  • 33’ → for shelters 16’ to 18’ wide (2 straps required)

ADVANTAGES

The Double Supra carport stands out for its curved roof, which acts as a natural windbreak. This shape allows for better air circulation around the structure, increasing its stability in exposed areas. A recommended choice for open areas or areas prone to strong gusts.

1. Remove snow quickly

Use a broom or a soft-headed squeegee (never a metal shovel).

Clear snow from the roof after every storm, especially heavy or wet snow.

2. Check the structure

Regularly inspect joints, bolts and anchors.

Tighten any loose screws or bolts.

Make sure the structure is securely anchored to the ground.

3. Check the canvas

Examine the canvas for any tears, wear, or sagging.
