Vinyl laminated tarps from Canopies and Tarps are built to handle the toughest jobs.

We know: 22 mil doesn't sound like a lot. One mil is a thousandth of an inch, after all. But when it comes to tarps, it's hard to find a waterproof tarp that is thicker than that. If you are wondering what is the thickest tarp you can buy, our 22-mil vinyl laminated tarps are at the top of the list.

Built for Tough Jobs

Our vinyl laminated tarps are made with an 18-ounce vinyl material that is constructed to be waterproof, UV-resistant, flame-retardant and superhumanly strong. The material is made to resist tears, punctures and abrasions, as well as mildew and oil. Heat-sealed seams and hemmed edges give them even more space, and grommets every 24 inches allow for precise placement.

That makes these an outstanding choice for construction or industrial applications:

Welding. These tarps can work as welding blankets or curtains to control sparks or spatter.
Chemical protection. If harsh chemicals are needed for a job, these tarps can keep them contained.
Transport and logistics. If you have a trailer full of loose material, stretch this tarp across the load to minimize loss and protect other drivers.
Protection of equipment or materials. Whether you have untreated lumber or expensive machinery, cover it up with a vinyl tarp to keep it safe from the weather.

FAQs

What makes an 18oz vinyl laminated tarp different from a standard vinyl tarp?

A1: An 18oz vinyl laminated tarp is significantly heavier and more durable than standard-weight options, featuring a laminated construction that bonds multiple layers of vinyl together for superior tear resistance and waterproofing. This weight class is ideal for heavy-duty industrial, commercial, or long-term outdoor applications where lighter tarps would fail under stress. If you need something lighter for general use, you can explore our broader selection of Vinyl Tarps in various weights and sizes.

How do I use an 18oz vinyl laminated tarp to cover a vehicle or equipment outdoors?

These tarps can be draped directly over vehicles, machinery, or equipment and secured using the reinforced grommets along the edges with rope, bungee cords, or tie-downs. For a more permanent or structured solution, consider pairing the tarp with a frame system — you can browse our Canopy Pipe Fittings & Tent Connectors to build a custom support structure, or check out our Portable Garages & Carports for Vehicle Protection for a ready-made sheltering option. Proper tensioning and anchoring will extend the life of the tarp and prevent pooling water.

Are 18oz vinyl laminated tarps waterproof and suitable for year-round outdoor use?

Yes, 18oz vinyl laminated tarps are fully waterproof and designed to withstand harsh weather conditions including heavy rain, UV exposure, wind, and cold temperatures. The laminated vinyl construction creates a seamless moisture barrier that far outperforms poly tarps in demanding environments. Their heavy weight and durability make them one of the best choices for year-round outdoor storage, job site coverage, and agricultural applications.

Can I use an 18oz vinyl laminated tarp as a replacement cover for a canopy frame?

While 18oz vinyl laminated tarps can technically be rigged over canopy frames, they are quite heavy and may not attach cleanly to standard canopy frame hardware. For a proper fit, you may want to look at our dedicated Replacement Canopy Covers, which are designed to match specific frame sizes and attachment systems. However, if you're building a custom heavy-duty structure, our Canopy Pipe Fittings & Tent Connectors can help you create a frame suited to support the extra weight of an 18oz vinyl tarp. Q5: Why should I choose an 18oz vinyl laminated tarp over a mesh or lighter tarp for industrial use? A5: For industrial applications where you need complete weather protection, containment, or privacy, an 18oz vinyl laminated tarp is far superior to lightweight or open-weave options. Unlike Mesh Sun Shade Tarps, which allow airflow and light to pass through, vinyl laminated tarps create a solid, impermeable barrier against rain, wind, dust, and debris. The 18oz weight class also offers exceptional longevity under heavy mechanical stress, making it the preferred choice for construction sites, freight covering, and long-term outdoor equipment storage.
