How to Reinforce Tarp Grommets for High Winds (2026)
Tarp grommets are the first parts to fail when winds pick up — a torn grommet can send a tarp flapping, damaging whatever it was protecting. This guide is for anyone who uses tarps in exposed areas: RV owners, contractors, boat owners, and backyard DIYers. You’ll learn practical reinforcement techniques (washers, clamps, seam folding), which materials and hardware reduce tear-through, and which commercial tarps are easiest to reinforce. Products below were selected for their thickness, reinforced edges, metal grommets, and consistent customer feedback about build quality and real-world wind performance.
Quick Answer
Reinforce tarp grommets by combining a heavy-duty tarp with metal grommets, welded or backed washers, and load-distributing hardware. The Xpose Safety 12' x 40' Super Heavy Duty 16 Mil tarp is our top pick because its 16 mil thickness, reinforced edges and metal grommets give a stronger starting point for storm-grade reinforcement.

Frequently Asked Questions
What's the quickest way to stop a grommet from tearing in high winds?
The fastest fix is to back the grommet with a large washer-style backing (metal or heavy-duty plastic) and switch to shock-absorbing tie-downs (elastic cord or bungee) to reduce sudden jerks. If the hole is already stretched, clamp the area with a tarp clamp or use a grommet repair kit and permanent washer patch to restore strength.
Can I reinforce grommets without replacing the tarp?
Yes. Common methods include adding large backing washers, applying heavy-duty seam tape around the hole, installing tarp clamps or tarp rings, sewing or riveting a strip of webbing along the hem to redistribute load, and using edge-folding/double-hem techniques. These methods allow you to upgrade holding strength without replacing the full tarp.
Which hardware reduces tear-through best: washers, clamps, or straps?
All three help, but they address different failure modes. Large backing washers spread load at the hole; clamps provide immediate bite and increased bearing area; sewn or riveted webbing straps move loads along the hem so individual grommets aren’t overloaded. For storms, combine a backing washer with webbing straps or edge reinforcement for the best protection.
