Ground Anchoring for Tiny Homes and Portable Buildings Built to Withstand the Unexpected

Tiny homes, transportable offices, modular site sheds, dongas, and other portable buildings offer freedom and flexibility. But that freedom comes with a challenge: how do you anchor a lightweight structure safely to the ground — without permanent foundations — and still comply with safety and wind load standards?

That’s where GroundGrabba offers the perfect solution.

Our purpose-built ground anchoring systems provide reliable, fast-deploying, and fully removable options for securing small, transportable structures. Whether it’s a tiny home parked in a rural paddock or a portable site office on a construction project, GroundGrabba anchoring kits help you hold fast in any weather.

Why Anchoring Matters for Portable Buildings

Unlike permanent homes, tiny homes and relocatable buildings aren’t typically mounted on deep concrete foundations. They're often set up on trailers, skid bases, or raised pads — which can make them vulnerable in high winds or shifting soil.

That’s why temporary yet strong anchoring is critical — not just for peace of mind, but often for insurance and compliance purposes.

• ✅ Protected against uplift and lateral movement in storms
• ✅ Secured without damaging the land or needing concrete
• ✅ Removable for future relocation
• ✅ Compatible with soft, sandy, hard-packed, or variable ground types

Introducing the GroundGrabba Tiny Home Tie Down Kit

The Tiny Home – Transportable Building Tie Down Kit is engineered specifically for lightweight residential structures that need reliable anchoring. This kit includes Commercial GroundGrabba anchors, ClosedHook14 fittings, and the hardware needed to create a durable tie-down system — keeping your building locked down in place even in harsh weather conditions.

It’s perfect for:

• Tiny homes on trailers or skids
• Granny flats or container pods
• Portable farm buildings or sheds
• Modular sales offices or pop-up booths

Whether you're off-grid, semi-permanent, or relocating regularly, this anchoring solution lets you remain flexible — without compromising on safety.

Heavy-Duty Anchors That Mean Business

At the heart of the kit are your choice of two industrial-strength anchors:

🔩 Commercial Pro I Pack

Designed for harder ground types, including firm clay and compacted dirt. These feature deep high-pitch threads and a 1" AF hex head — allowing you to drill them in quickly and easily using a powerful cordless drill and hex socket. Perfect when you're anchoring to solid soil with minimal give.

🔩 Commercial Pro II Pack

Built for softer or looser soil types, such as sandy pads, unpacked earth, or temporary set-up sites. The Pro II offers greater length and more aggressive threading to ensure strong grip even in marginal terrain.

Each Commercial anchor is forged from galvanised carbon steel, offering durability and corrosion resistance — ideal for long-term outdoor exposure.

ClosedHook14 — Secure Your Frame to the Ground

The ClosedHook14 is a steel connector designed to interface with your Commercial GroundGrabba anchors. It slides over the hex head and sits flush with the ground, offering a secure, closed-loop attachment point for tie-down straps or cables.

When used in combination with our anchors, ClosedHooks provide:

• Strong, fixed anchor points for tethering
• No risk of rope slippage or “pop-off”
• Clean, low-profile finish to your ground connection

They’re especially useful when anchoring through engineered structural points like skid loops or base rail holes on your tiny home chassis.

Tethering Kit — Build a Foundation Without Concrete

The GroundGrabba Tethering Kit combines everything you need to create an effective temporary anchoring system. Use it to tie down structures in a way that’s compliant, repeatable, and relocatable.

Key features:

• Works with all GroundGrabba Commercial anchors
• Easy to tension and adjust on-site
• Suits wind-prone locations or regions with strict safety codes

Whether you're preparing for a council inspection or just want peace of mind during storm season, the tethering kit makes anchoring a breeze.

Easy Installation With a Drill

Forget concrete pours and heavy excavation. GroundGrabba anchors are:

• Drill-driven with a cordless drill and a hex socket
• Installed in minutes, even on tough terrain
• Reusable — just reverse the drill to remove
• Non-destructive — won’t scar the land or leave permanent fixings

For our Commercial anchors, simply use a 1" AF impact hex socket with a high-torque impact wrench.

This article will discuss the different types of semi-permanent ground anchoring, the benefits of using them, and how to use GroundGrabba earth and ground anchors to secure your tiny home or portable shed.

Introduction – What is a “Tiny Home” and Why Would You Need Earth Anchoring?

A tiny home is a small dwelling, usually on wheels, that is typically no more than 500 square feet in size. Tiny homes are growing in popularity due to their affordability, mobility, and sustainability. However, due to their lightweight construction, they are particularly vulnerable to strong winds and other adverse weather conditions. Thus, it is essential to use semi-permanent earth ground anchors to secure your tiny home.

Similarly, portable sheds, donga's and other portable structures like emergency shelters or pop-up housing are also vulnerable to strong winds and adverse weather conditions. Thus, it is important to use ground anchoring solutions to secure these structures also.

Types of Semi-Permanent Ground Anchoring

There are several types of semi-permanent ground anchoring solutions available on the market. These include reusable ground anchors, tie-downs, and ground stakes. Reusable ground anchors are typically made from heavy-duty materials and are designed to be used multiple times.

Tie-downs are designed to be used in conjunction with reusable ground anchors and are typically made from nylon or polyester webbing, chain or steel cable. Your average ground stakes are designed to be hammered into the ground and are usually made from steel or aluminum.

GroundGrabba ground anchors are made from galvanized carbon steel. They are screwed into the ground and are based on an auger design that doesn't just rely on the surrounding earth's resistance and density but also creates a kind of conical shape of earth that weighs down on top of the augur flutes or what we call 'flights'. So, you get a kind of double hold-down effect. This is why GroundGrabba can hold between three and six times more* than your conventional hammer-in stakes.
