Tank and Silo Ground Anchors and Tie Downs

Above-ground water tanks and small agricultural silos often face unexpected stress from wind gusts, shifting soil, or uneven fill levels — especially when installed on raised pads or in exposed paddocks. Without proper anchoring, these tall, hollow structures can tip, lean, or slide, risking damage to nearby property and the tank itself.

GroundGrabba’s range of heavy-duty screw-in anchors provides a robust, drill-powered solution for keeping tanks and silos securely tethered in place. Whether for rural, industrial, or backyard use, our systems deliver the holding power you need with the ease of installation you want.

Pro II Packs

Built for more demanding anchoring jobs, the GroundGrabba Pro II is 615mm long with aggressive flighting to bite deep into sand, soft soil, or mixed ground types. Ideal for stabilising lightweight tanks and temporary silos where movement prevention is critical. Pro II Packs offer a convenient kit with anchor, attachment, and driver tool.

Commercial Pro I Packs

At 600mm long with a 15mm shaft, the Commercial Pro I provides excellent stability for medium-duty applications in firmer soils. A strong choice for securing small to mid-sized tanks or feed bins in agricultural settings. Drives in fast with an impact wrench, and holds strong under tension or wind load.

Commercial Pro II Packs

Our longest and most robust option, the 900mm Commercial Pro II delivers serious anchoring power in challenging conditions. Ideal for large silos or heavy storage tanks, especially in high-wind or flood-prone areas. Deep-set flighting and 15mm shaft ensure maximum ground engagement.

Multi L Bracket

The Multi L Bracket is designed to convert your GroundGrabba anchor into a structural mount point. Perfect for tying down the base frames of silos or tanks, it allows for multiple cable or bolt connections. Made from hot-dip galvanised steel for long-term outdoor use.

From the founder:

Hi, I’m David Levine, inventor of GroundGrabba. In 2017, Susu and I set out to create purpose-built ground anchors. Today, our range secures everything from tents to tiny homes. We back our steel anchors with a Lifetime Replacement Warranty* and a 100% RISK-FREE 12-month return policy. Whatever you need to anchor, we’ll keep you grounded.

Closed Hook 14

Used alongside our GR14 commercial anchors, the ClosedHook 14 provides a strong tethering loop for guy wires, cables, or chain. Its enlarged tear-drop hole suits the wider 15mm shaft of our Commercial series, delivering a secure interface between anchor and tie-down system in agricultural or industrial environments.

Tank and Silo Ground Anchors and Tie Downs

Large water tanks, fuel storage containers, and agricultural silos are vital infrastructure across farms, remote communities, mine sites, and rural properties. But without proper ground anchoring, even the heaviest tanks can shift, tilt, or overturn — especially when they're empty or partially filled. Add wind gusts, soft soil, or sloped terrain, and you’ve got a recipe for movement that can cause damage, leaks, or costly downtime.

GroundGrabba offers an engineered, heavy-duty anchoring system purpose-built for securing tanks and silos to the ground without concrete. Whether you're managing water capture systems, diesel fuel storage, fire suppression reserves, or grain silos, the combination of downward weight and upward wind lift requires a solution that holds in both directions. That’s where our drill-driven ground anchors come in.

Designed for rapid deployment and long-term stability, our Commercial Pro I and Commercial Pro II ground anchors are made for high-load, high-risk setups. At 600mm and 900mm long respectively, with robust 15mm shafts and aggressive flighting, they drive deep into a wide variety of soils — from clay and compacted gravel to loam and sandy ground. Unlike rebar pins or star pickets, GroundGrabba screws in tight, locks in place, and resists both lateral and vertical movement.

Need additional tie-down support? Our Multi L Bracket system allows fixed connections between your tank’s structural base and the ground anchors. This offers tension-ready anchoring points, ideal for systems using cable tie-downs or direct bracing. It’s a preferred option for steel tanks or modular silos with flat steel or timber skids.

When a removable, relocatable anchoring method is needed — especially for temporary deployments or when tank servicing is frequent — the GroundGrabba system shines. Simply reverse your impact wrench to unscrew the anchor and reposition as required. No digging. No permanent footings. Just solid holding power when and where you need it.

Our ClosedHook 14 attachment point adds further versatility. Designed for our Commercial (GR14) series of anchors, its large teardrop-shaped hole accommodates the thicker 15mm shaft and collar, providing a reliable link for shackles, cable loops, or bracing systems. It’s ideal for high-load applications where secure fastening is non-negotiable.

GroundGrabba anchors are also compatible with a wide range of tank and silo base designs — including raised bases, metal frame skids, or direct-to-ground installs — offering flexibility for farm, industrial, and emergency use cases.

Best of all, the entire system is reusable, field-serviceable, and built tough for Australian conditions. From cyclone-prone areas to remote drought recovery zones, GroundGrabba delivers confidence with every install.

So whether you’re managing rural water infrastructure, temporary diesel depots, or fixed-site grain silos, GroundGrabba’s range of commercial ground anchors and accessories offers a modern solution for tank and silo security — without concrete, without compromise.
