Heavy Duty Poly Tarp 20 ft x 40 ft 10 Mil Thick Waterproof - Durable

In this review of the Heavy Duty Poly Tarp 20 ft x 40 ft 10 mil thick waterproof cover, the bottom line is simple: this tarp is for homeowners and jobsite users who need a large, economical weatherproof barrier that balances weight and protection. The standout reason to consider it is its 10 mil laminated polyethylene construction combined with UV blocking, which delivers dependable water and sun protection for items like pool covers, wood stacks, and equipment. It is a straightforward, no-frills tarp that performs well for basic outdoor protection.

Key Features

• 10 mil thickness: Provides a thicker-than-standard sheet that resists punctures and tears better than very thin tarps for longer outdoor use.
• Waterproof laminated coating: Keeps rain and moisture off stored items so covered pools, woodpiles, and gear stay dry through wet weather.
• UV blocking: Helps reduce sun damage and fading to covered surfaces when left outdoors for extended periods.
• Reversible green and black: Gives flexibility in appearance and reflective properties depending on which side faces out.
• Reinforced grommets: Spaced about every 18 in on the edges so the tarp can be securely tied down and fastened in windy conditions.
• Large finished size: The 20 ft x 40 ft sheet covers bulky items and can be used for construction, landscaping, or storage protection.

Who It's For

This tarp suits homeowners, landscapers, and contractors who need a large, economical cover for seasonal protection of pools, lumber, equipment, or material piles. Its size and grommet placement make it practical for tying down across wide spans and its laminated face offers clear waterproofing benefits.

It is less appropriate for users requiring industrial-grade, heavy canvas performance or specialty fabrics with extreme tear resistance; customers seeking long-term military- or marine-grade longevity under constant abrasion may want a heavier industrial option.

Pros & Cons

• UV blocking extends life of covered items by reducing sun exposure.

Cons

• Some users report mixed durability-while many find the thickness sufficient, others have experienced rips under heavy stress or prolonged harsh use.
• 10 mil is thicker than lightweight tarps but may not match industrial canvas for long-term abrasion resistance.
