A Waterproof Tarp That Will Last

Stop replacing cheap import tarps and buy one that will stand the test of time. This tarp's 20 mil (≈10 oz / yd²) woven core is quite a bit lighter than solid vinyl, making the tarp easier to deploy. Despite the weight, 2500 denier yarn strength, heat welded seams and hems, high tear strength, and -40 °F cold resistance make this a very robust option. Poly tarps are great for:

• Enclose exposed worksites , protecting from wind and rain
• Cover objects being stored outside
• Keep hay, firewood, and other perishables dry
• Protect gardens and plants from bad weather
• Serve as a ground sheet for camping and outdoor events

Constructed to Eliminate Points of Failure

Robust Construction

• Welded seams and hems are quite a bit stronger than sewn, and don't have holes that compromise water resistance
Outer coating is 70 % thicker than standard poly tarps, offering increased resistance to punctures, tears, and abrasions

Reinforced Edges and Hardware

Double-thick hems are heat-sealed for extra strength
#4 spurred brass grommets with 1/2" I.D. every 24 inches provide even tie-down tension
Twin grommets in each corner allow for secure attachment that won't blow out in wind

Poly That is Too Tough to Tear

Since our early days, we have been crafting durable covers, a legacy that shapes our heavy-duty polyethylene tarps today. Made from thick, woven poly with a waterproof coating, these tarps are designed to endure harsh weather, UV exposure, and rugged use. The quality standards we set years ago continue to guide every tarp we produce.

Check out our 1970s ad—it shows proof that reliable craftsmanship never fades.

American Ingenuity in Every Seam

For decades, Humphrys has turned high-density woven polyethylene into tarps that work as hard as you do. In our Indiana facility, we cut the coated fabric, heat-weld the seams and hems (as you can see here), set the grommets, and thoroughly inspect each tarp. The cross-woven poly blocks water, resists tearing, and shrugs off UV damage, making these tarps a dependable choice. Built start to finish in the USA, they are ready for years of service.

Standard Features

heavy duty poly twin grommet zoomed
Double-Thick Hems: Our tarps are made with heat-sealed hems. The fabric is folded back on itself and then welded in place for an incredibly robust edge.
Black Brass Grommets: Every 2 feet we put a 1/2" inner diameter brass grommet. These grommets will not corrode, and can be counted on to stand up to long use and demanding tasks.

Options for Made-to-Order Tarps:

Grommets with Reinforced Patches: Made for tension-heavy jobs such as construction work, this option has reinforced polyester patches around each grommet. The #4 rolled rim brass grommets offer a 1/2" inside diameter. Made in America from weather-resistant brass.

D-Rings with Reinforced Patches: Ideal for securing large loads, this configuration uses webbing and steel-plated zinc D-rings plus four-layer polyester patches. The 1-1/8-inch D-rings accommodate standard webbing and handle heavier weights. Made in America, they remain reliable in harsh conditions.

Rope in Hem: Adding a rope to the hem of the tarp has been a popular way of ensuring the tarp against tension for decades. Sewn to attachment points in between the layers of the hem, the rope will take the strain of weight, wind, and tension, saving the fabric around it and substantially increasing the loads the tarp can withstand.
