Keten Tarps Heavy Duty Waterproof 12x20 ft - Extra Thick Protection

In this review the Keten 12x20 ft tarp is assessed as a heavy duty, all-season cover for outdoor equipment and temporary repairs. The bottom line: it is best for homeowners, campers, and boat owners who need a thick, waterproof sheet that resists tearing and UV damage. The single biggest reason to buy is the tarp's substantial 16 mil thickness and reinforced construction, which provide reliable protection from rain, wind and sun without frequent replacement.

Key Features

• 16 mil thickness: The extra-thick polyethylene gives long-lasting protection and resists punctures under heavy use.
• 15 x 17 weave: A dense weave improves tear resistance and overall durability compared with lighter tarps.
• Reinforced grommets: Heavy-duty grommets spaced every 23 in allow secure tie-downs and reduce stress points during high wind.
• Double hemmed and heat sealed: Edges are reinforced to prevent fraying and extend the tarp's usable life in rough conditions.
• Waterproof and UV resistant: The silver/black coating blocks sun damage and keeps moisture out for year-round outdoor coverage.
• Plastic corner reinforcements: Additional corner protection lowers the chance of tears when anchoring or hauling the tarp.

Who It's For

The tarp is aimed at DIY homeowners, campers and boat owners who need a dependable, heavy duty cover for roofs, pools, outdoor furniture, wood piles and trailers. It works well as a groundsheet or emergency shelter when you want a robust, waterproof layer that stands up to storms.

Those who should look elsewhere include buyers seeking lightweight, ultra-compact tarps for backpacking or those who need a decorative cover; this product is built for strength and protection rather than minimum weight or indoor aesthetics.

Pros & Cons

Pros
