Green Heavy Duty Tarp 12x20 ft 12 Mil - Durable Waterproof Cover

In this review of the Green Heavy Duty Tarp 12x20 ft, the bottom line is straightforward: this tarp is aimed at homeowners, contractors, and outdoor enthusiasts who need a midweight, weatherproof cover that balances strength and manageability. The single biggest reason to buy is the 12 mil thickness combined with a 14x16 weave and reinforced edges, which delivers far better tear and puncture resistance than lightweight tarps while remaining easier to handle than ultra heavy options. This review examines build quality, fastening points, and real-world uses observed during extended outdoor exposure.

Key Features

• 12 mil thickness: Provides a sturdy middle ground between flimsy and overly heavy tarps, resisting rips while staying reasonably flexible for handling.
• 14x16 weave count: The dense weave improves durability and helps shed water and debris rather than trapping it on the surface.
• Anti-rust grommets every 20 in: Metal grommets spaced regularly make it easy to secure the tarp with rope or bungee cords for reliable tie-downs.
• Reinforced corners and thickened side cords: Plastic triangle corner reinforcements and strengthened edges reduce stress points and extend the life of the cover.
• Weatherproof and UV resistant: The polyethylene construction provides waterproof protection and UV resistance suited for outdoor storage and storm protection.

Who It's For

This tarp is well suited for homeowners covering patio furniture, wood piles, or small roofs, contractors needing a portable protective cover, and campers who want shelter from wind and rain without lugging a heavy tarp. It also works for boat and pool covers in seasonal use.

People who need a brute-force tarpaulin for constant heavy-duty industrial use, or who prefer an ultralight tarp for backpacking, should look elsewhere; this 12 mil option is a compromise designed for general outdoor work and occasional heavy exposure rather than nonstop commercial abuse or minimalist camping.

Pros & Cons

Pros

• Durable 12 mil thickness offers strong puncture and tear resistance compared with lightweight tarps.
• Regular anti-rust grommets every 20 in make securing and tie-down straightforward.
• Reinforced corners and thickened side cords add useful longevity under tension and windy conditions.
• Waterproof and UV protective material holds up well for outdoor seasonal use.

Cons

• At 12 mil it is heavier than thin tarps, so handling and folding may be a little more cumbersome.
• Not intended for continuous, industrial-grade tarping where 16+ mil products are preferred.
