8 Supplies for Securing Tarps in High Winds

A sudden mid-autumn gale can transform an improperly secured farm tarp into a massive, shredding sail in seconds. Protecting valuable round bales, tractor implements, or seasonal crop beds requires far more than tossing a few concrete blocks onto plastic sheeting. Equipping a small homestead or hobby farm with the right tie-down hardware ensures your investments remain dry, secure, and intact when severe weather strikes.

Understanding Wind Loads on Small Farm Tarps

When wind sweeps across a tarped hay stack or machinery pile, it generates intense aerodynamic lift. The moving air creates high pressure on the windward side and low pressure directly above and behind the cover. If air slips under an unsealed edge, this upward lifting force doubles instantly, threatening to tear the cover clear off its anchors.

Wind rarely exerts a static, steady pressure; it gusts violently. These sudden surges create dynamic shock loads that violently snap tied lines and stress mechanical fasteners. A gentle breeze exerting minimal force can rapidly spike into hundreds of pounds of sudden force during a 40-mph wind gust.

Standard grommets fail under these conditions because they concentrate dynamic shock forces onto tiny rings of fabric. Without elastic dampeners or proper load distribution across the canvas, the material around the grommet shears apart. Understanding these physical forces is the first step toward building a storm-proof cover setup.

Heavy-Duty Bungee Cord – Keeper Super Duty Cord

Rigid tie-downs installed with zero elasticity often fail during high winds because they cannot absorb sudden kinetic shock. Heavy-duty bungee cords act as dynamic shock absorbers along guy-lines, expanding under violent gusts to dissipate energy before it reaches the tarp fabric.

The Keeper Super Duty Cord stands out for farm applications thanks to its sheathed steel hooks that will not bend under tension or mar equipment frames. The weather-resistant outer jacket protects an internal core of premium rubber from friction and moisture, maintaining spring tension across wide temperature swings.

• Hook Style: Vinyl-coated, non-marring steel core
• Core Material: High-grade natural rubber
• Best Uses: Implement covers, firewood racks, small utility trailers

Bungee cords feature a finite stretch limit, typically extending up to 50 percent beyond their relaxed length. Over-stretching forces the rubber core past its elastic limit, destroying internal fibers and creating dangerous snap-back risks. Routinely inspect the woven jacket for fraying or sun bleaching before severe weather hits.

This cord is ideal for securing covers over small equipment trailers, stacked firewood, or rounded implements where flexible tension is required. It is not suitable as a primary anchor for high-clearance structures like livestock hoop shelters or multi-tier hay stacks.

Tarp Grabber Fastener – Grip Clip Heavy Duty

Factory grommets are rarely located exactly where you need them on custom farm setups. Tarp grabber fasteners allow you to instantly create heavy-duty tie-down points anywhere across the fabric surface without punching damaging holes through the material.

The Grip Clip Heavy Duty utilizes an innovative wedge-and-ring friction system that grips broader fabric areas without pinching or tearing woven fibers. Its unique wedge design actually increases its grip strength as wind tension pull increases, preventing slippage under heavy dynamic loads.

• Holding Mechanism: Circular wedge-and-ring lock
• Material: UV-stabilized high-impact polymer
• Best Uses: Folded tarps, custom-trimmed covers, center-span guy lines

These grabbers require heavy-duty woven polyethylene, canvas, or vinyl covers to bite effectively. They struggle to hold smooth, ultra-thin 4-mil plastic drop cloths or severely worn covers where the structural weave has degraded.

This fastener is perfect for farmers who fold or trim oversized tarps to fit irregular machinery or custom compost beds. Skip this option if you work exclusively with thin, disposable plastic sheeting that lacks structural thread support.

Spiral Ground Anchor – ShelterLogic Earth Anchor

Securing tarps in open pastures or field edges often means working far from trees, fence posts, or heavy outbuildings. Spiral ground anchors provide deep, solid tie-down points driven directly into the soil to hold structural guy-lines firmly in place.

The ShelterLogic Earth Anchor features heavy-gauge corkscrew steel construction mated to high-tensile steel cables. The spiraled auger design drills deeply into soil, yielding hundreds of pounds of pull-out resistance per anchor point even in soft terrain.

• Anchor Material: Powder-coated heavy-duty steel
• Attachment: Steel cable with clamp assembly
• Installation: Manual turn-rod or drive pipe

Installation requires a drive rod or rebar handle to twist the corkscrew past embedded roots and dense soil layers. Dry clay and rocky subsoils require drilling a small pilot hole or soaking the insertion area with water to ease installation.

These anchors are essential for securing field-stored round bales, silvopasture nursery covers, and field shelters against wide-open gales. They are unsuited for frozen winter soil or heavily gravelled driveway pads where the corkscrew cannot penetrate.

Ratchet Tie-Down Strap – Rhino USA Heavy Duty

When holding massive, heavy-duty tarps down over rigid structures, hand-pulled ropes often leave too much slack. Ratchet straps provide immense mechanical advantage, letting you crank down tarps snugly across structural frames so wind cannot get underneath.

The Rhino USA Heavy Duty Ratchet Strap features anodized padded handles, a heavy 1,800 lb break strength, and coated S-hooks with spring safety latches. Its smooth ratcheting mechanism resists binding even when coated in field dust, mud, or moisture.

• Break Strength: 1,800 lbs (598 lbs working load limit)
• Hardware: Anodized steel with safety latches
• Webbing: High-tenacity weather-coated polyester

Excessive mechanical leverage can crush light wooden framing, bend thin conduit tubing, or slice through cheap tarps. Always install corner edge protectors or heavy rubber pads where straps cross sharp structural corners to prevent fabric abrasion.

This strap is excellent for locking tarps onto utility trailers, lumber stacks, and heavy equipment frames. It is far too aggressive for delicate low-tunnel garden beds or thin, unsupported poly covers.

How to Angle Tie-Down Lines for Maximum Hold

The angle of your tie-down lines directly dictates whether an anchor holds or pulls free in a storm. Running guy-lines straight down at a 90-degree angle to the ground places intense vertical stress on tarp grommets and increases the risk of anchor pull-out.

Setting guy-lines at a 45-degree angle relative to the ground plane provides the ideal balance of downward tension and lateral resistance. This geometry distributes force evenly across the anchor point, helping the tarp resist side gusts while staying pinned flat to the earth.

• Optimal Guy-Line Angle: 45 degrees relative to ground level
• High-Profile Load Offset: Set anchors outward a distance equal to half the stack height
• Corner Line Placement: Extend lines diagonally outward along the corner bisector

For tall structures like stacked hay or equipment, position ground anchors outward from the base rather than right against the side walls. Extending the footprint creates a wider anchor base that stabilizes the entire cover against directional wind shifts.

Elastic Ball Bungee – XSTRAP Heavy Duty Tie

Securing tarps to tubular pipe frames, greenhouse hoops, or chain-link enclosures requires rapid, repeatable attachment points. Elastic ball bungees loop around structural tubing and back over their anchor ball to provide constant, spring-loaded retention.

The XSTRAP Heavy Duty Elastic Ball Bungee utilizes a high-grade virgin latex core paired with an impact-resistant composite ball. Its durable woven outer jacket resists intense UV degradation, keeping the internal elastic core supple through hot summer sun.

• Core Material: High-grade virgin latex
• Ball Construction: Molded high-impact composite
• Best Uses: Hoop houses, caterpillar tunnels, pipe-frame shelters

Matching the bungee length to your pipe diameter is critical for proper operation. If the cord loop is too long, the tarp will flutter in light winds; if too short, stretch limits will be exceeded during installation.

These ties are ideal for hobby farmers managing chicken tractors, caterpillar tunnels, and canopy storage units. They are not designed for long ground-to-tarp spans where high linear movement takes place.

Heavy-Duty Sandbag – Sandbaggy UV Poly Bags

High winds frequently lift covers by catching the bottom perimeter edges. Sandbags provide heavy, continuous ballast along ground edges, sealing the tarp flush to the earth to stop wind from blowing underneath.

Sandbaggy UV Poly Bags are woven from 1600-hour UV-rated polypropylene, designed to resist sun degradation over extended outdoor deployments. The tight weave holds fine ballast without leaking, while the integrated tie strings make closing filled bags quick and secure.

• UV Rating: 1,600 hours of direct sunlight exposure
• Material: Dense woven polypropylene
• Closure: Double-stitched seams with built-in tie strings

Never fill sandbags to capacity; fill them two-thirds full so they remain pliable and lay flat against the ground. Using washed pea gravel instead of soil or sand promotes water drainage and prevents the bags from soaking up heavy rain and decomposing.

• Recommended Fill Level: 60–70% capacity (30–40 lbs)
• Ideal Fill Material: Washed pea gravel or coarse crushed stone
• Placement Interval: 2–3 feet along windward perimeter edges

These bags are essential for securing ground covers, silage tarps, and compost blankets directly against the earth. They are impractical for elevated structures where ground ballast cannot reach the tarp edge.

Locking Tarp Clamp – TEKTON Heavy Duty Clip

Unpredicted wind storms can rip out standard grommets or create mid-span billowing that requires immediate tie-downs. Locking tarp clamps give you quick emergency gripping power on hemmed edges or flat canvas spans.

The TEKTON Heavy Duty Clip utilizes a slide-locking jaw mechanism lined with aggressive serrated teeth. This design multiplies its holding force as wind pull increases, preventing fabric slippage even on thick, multi-layer covers.

• Jaw System: Sliding wedge lock with serrated teeth
• Material: Weatherproof glass-filled nylon
• Best Uses: Mid-span tie-downs, hem repairs, quick storm prep

Sharp serrated teeth can leave deep indentations or scratch thin protective coatings on lightweight covers. When clamping smooth, thin 6-mil plastic sheeting, fold a strip of heavy duct tape over the tarp edge first to cushion the jaws.

This clamp is a critical emergency item to keep in your barn or truck for quick storm prep and field repairs. Avoid using it on soft, stretchy film covers that easily tear under targeted jaw pressure.

Braided Utility Rope – SGT KNOTS Dacron Rope

Long guy-line spans and multi-point perimeter tiedowns require strong, low-stretch cordage that holds knots securely. Braided utility rope links anchors, structures, and tarps together into a rigid, storm-resistant system.

SGT KNOTS Dacron Rope features a solid-braid polyester construction that offers exceptionally low stretch under high tension. Unlike standard nylon line, Dacron retains its length when wet and resists rot, mold, and harsh sun exposure season after season.

• Fiber Type: 100% solid-braid Dacron polyester
• Stretch Profile: Ultra-low stretch under dynamic load
• Resistance: UV, rot, chemical, and moisture resistant

Polymer ropes require reliable knot-tying techniques to maintain tension under load. Master simple knots like the trucker’s hitch for mechanical tensioning and the bowline for non-slip end loops to maximize line performance.

• Trucker’s Hitch: Creates 2:1 mechanical advantage for tensioning
• Bowline: Forms a secure, non-slip loop at anchor points
• Taut-Line Hitch: Allows easy line-length adjustments

This rope is the premier choice for long-term farm rigging, main guy-lines, and securing high stack tarps. Do not use it where elastic shock absorption is needed, as polyester rope has virtually no stretch.

Checking Tarp Tension After High Wind Events

Securing a farm cover is not a single task; it requires ongoing attention after storms pass. Strong gales stretch synthetic fibers, loosen rope knots, and shift ground anchors, leaving tarps loose and exposed to the next storm front.

Walk around your covered areas immediately after high wind events pass. Check perimeter sandbags for movement, test rope lines for slack, and look over every grommet for initial stress tears or stretching around the brass rings.

• Inspect Line Tension: Pluck guy-lines; tighten any lines that feel slack
• Check Anchor Depth: Ensure ground augers have not lifted or loosened in wet soil
• Examine Contact Points: Inspect structural edges for fabric wear or fraying

Re-tension loose guy-lines immediately using ratchet adjustments or friction hitches. Eliminating small amounts of slack right away prevents minor cover flutters from expanding into total structural blowouts during the next wind storm.

Preventing Grommet Tear-Out on Farm Covers

Grommet tear-out is the single most common cause of tarp failure on small farms. It occurs when dynamic wind forces concentrate onto a single metal ring, exceeding the shear strength of the surrounding woven plastic threads.

Combine rigid tie-down lines with elastic shock absorbers like ball bungees or heavy spring dampeners. Flexible connectors absorb peak kinetic energy from wind gusts, dampening shock loads before they reach the grommet rim.

Spread tie-down forces over wider areas using tarp grabbers, locking clamps, or continuous sandbag ballast. Distributing wind loads across multiple contact points ensures no single grommet bears the full force of incoming gusts.

• Use Elastic Dampeners: Insert bungees between grommets and rigid lines
• Spread the Load: Add intermediate tarp clips between factory grommet spaces
• Pad Sharp Corners: Place foam or rubber padding over structural frame edges

Building a wind-resistant securing system on the farm comes down to combining flexible dampeners, solid ground anchors, and proper tie-down geometry.
