16Mil Tarps Heavy Duty Waterproof 16x20 ft - Durable All-Season Cover

In this review of the 16Mil Tarps Heavy Duty Waterproof 16x20 finished size tarp, the bottom line is simple: this is a practical, heavy-duty cover for outdoor projects and storage where long-term protection matters. Built from tightly woven HDPE fibers with a thick 16Mil coating, it suits homeowners and contractors who need a reusable, tear-resistant tarp that stands up to sun and rain. The single biggest reason to buy is the combination of reinforced edges and rustproof grommets, which make it reliable for tiedown and repeated use.

Key Features

• Finished Size: The 16x20 ft dimensions provide broad coverage for vehicles, firewood piles, and equipment and work well for temporary roof repairs.
• 16Mil Heavy Duty Construction: Made from tightly woven HDPE fibers at about 8.5 oz/sq yd and a 15x16 weave count, the material feels thick and resists tearing under typical outdoor use.
• Reinforced Edges & Corners: Double-hemmed heat sealing with plastic caps strengthens vulnerable points so the tarp holds grommets and tie-downs without fraying.
• Rustproof Aluminum Grommets: Grommets placed every 23.6 in give many secure anchor points for ropes or bungee cords, improving stability in wind.
• All-Season Sides: The silver side reflects sunlight in summer while the black side helps absorb heat in cooler months, adding seasonal versatility.
• Easy Care: The double-sided waterproof coating wipes clean and the tarp folds compactly for storage and reuse.

Who It's For

This tarp is aimed at homeowners, small contractors and outdoor hobbyists who need a durable, reusable cover for items like lawn tractors, firewood, hay bales, or temporary roof protection. It is especially useful when reinforced corners and widely spaced grommets are required to secure loads in moderate wind.

Those with precise sizing needs or professional users needing certified industrial tarps should measure carefully before purchase; some buyers reported mixed impressions about size accuracy. If you need a custom-fit cover or very fine-grain waterproofing specifications, a tailored solution may be better.
