6 Best Ground Screws For Freezing Temperatures That Prevent Frost Heave
Prevent frost heave in cold climates with the right ground screws. We review the top 6 options that anchor below the frost line for a stable foundation.
There’s nothing more frustrating than seeing your perfectly level shed door jammed shut after a hard winter. Or finding a line of fence posts pushed crooked, leaning like tired soldiers. This is frost heave in action, and it’s a constant battle for anyone building in cold climates.

How Ground Screws Defeat Winter Frost Heave
Frost heave happens when water in the soil freezes and expands, pushing everything above it upwards with incredible force. A traditional concrete pier, with its wide, rough surface, gives this frozen soil a perfect handle to grab and lift. Your foundation becomes an anchor for the ice.
Ground screws work on a completely different principle. They are long, galvanized steel screws drilled deep into the earth. The magic is that their helical blade—the part that bears the load—is installed below the frost line, in stable, unfrozen soil.
The narrow steel shaft that passes through the frost zone offers almost no surface area for the frozen ground to grip. The ice simply can’t get a purchase to lift it. This elegant design sidesteps the entire problem, keeping your structures exactly where you put them, year after year.
American Ground Screw U-Model for Heavy Loads
When you’re building something substantial, like a small pole barn for your tractor or a permanent greenhouse, you need a foundation you don’t have to think about twice. This is where heavy-duty models like the American Ground Screw U-Model shine. Their U-shaped top bracket is designed to cradle heavy beams securely.
These screws are built for serious loads. They are often larger in diameter and made of thicker-gauge steel, ensuring they can support the weight of a structure plus heavy snow loads. You’re not putting these in with a handheld drill; they typically require professional installation with hydraulic equipment.
The tradeoff is cost for certainty. While you’ll pay more for a professional install, you’re getting a certified foundation. For a building that protects valuable animals or equipment, that peace of mind is worth every penny.
Krinner Ground Screws for Fences and Decking
For lighter-duty jobs, you don’t need a cannon to kill a mosquito. Krinner is a well-known name that offers a range of screws perfect for the projects that dot a hobby farm: fencing, small decks, and support posts for trellises or bird netting.
Their main advantage is accessibility and ease of use. Many of their smaller models can be installed by one person with a powerful impact wrench or a simple T-handle tool. Imagine setting the posts for a 100-foot fence line in an afternoon, with no digging, no mixing concrete, and no waiting for it to cure.
This also makes them fantastic for temporary or modular setups. If you practice rotational grazing and need to move a paddock fence for your sheep, you can simply unscrew the posts and reinstall them elsewhere. That’s a level of flexibility you can only dream of with concrete.
GoliathTech Helical Piles for Deep Frost Lines
If you live where winter is no joke and the frost line is measured in many feet, you need to bring in the big guns. GoliathTech specializes in helical piles, which are essentially the bigger, tougher sibling of the ground screw. They are engineered for serious structural support in the most demanding conditions.
These piles can be extended with additional sections to reach whatever depth is necessary to get below a deep frost line and find solid, load-bearing soil. This makes them the go-to choice for the foundations of larger structures like a cabin, a two-car garage, or a large workshop on your property.
This is not a DIY product. Installation requires specialized hydraulic machinery that not only drives the pile but also measures the torque. This data confirms the pile has reached the required load-bearing capacity. It’s a professional-grade solution for a permanent, worry-free foundation.
StopDigging Screws for Sheds and Outbuildings
The name says it all. This brand is a direct challenge to the old way of digging and pouring concrete for every small structure. They offer a versatile system with different screw models and attachment heads perfect for the most common hobby farm buildings: chicken coops, run-in shelters, and woodsheds.
One of the biggest wins here is the minimal site impact. You aren’t excavating huge holes or dealing with a mess of concrete slurry. This is a clean, fast installation that preserves the integrity of your soil—a point that matters to those of us who work the land.
StopDigging hits a great balance. Their products are robust enough for most outbuildings but are often simple enough for a determined DIYer to install with rented equipment. It’s a practical, modern approach that saves an immense amount of back-breaking labor.
Techno Metal Post P1 for Rocky, Frozen Terrain
Sometimes the biggest challenge isn’t the frost, but the ground itself. If your farm is built on soil that’s more rock than dirt, a standard ground screw can be stopped dead. This is where a specialized system like Techno Metal Post becomes essential.
Their proprietary installation equipment is designed to power through incredibly difficult ground, including rocky soil and even frozen earth. The P1 model, while one of their smaller posts, is still incredibly tough and can be fitted with a variety of heads for different applications.
Choosing this system is about acknowledging a tough problem and using the right tool to solve it. Instead of fighting your ground with a shovel and a broken spirit, you hire a certified installer who can guarantee a solid footing, regardless of the conditions. It turns a potential project-killer into a solved problem.
Pyradeck Adjustable Screws for Uneven Ground
Let’s be honest: perfectly flat ground is rare on any real-world property. Building a level structure on a slope is a classic headache. Pyradeck’s adjustable ground screws are a brilliant solution to this exact problem.
The key feature is an adjustable threaded head that sits on top of the installed screw. This allows you to fine-tune the height of each support after the screws are in the ground. You can create a perfectly level plane for your deck or shed floor without endless measuring, shimming, and re-digging.
Think about building a raised platform for your water tanks or a small deck off your barn on a slight grade. With these screws, you install them to the proper depth, then simply turn the heads up or down with a wrench until your level reads true across the entire frame. It’s a massive time and frustration saver, especially for solo or DIY projects.
Choosing Screw Length for Your Local Frost Depth
This is the single most important decision you will make. Your ground screw’s helical blade must be installed deeper than your local frost depth. If it isn’t, you’ve wasted your money, as the screw will heave just like a concrete pier.
First, you need to know your number. Your local building authority or county extension office can provide the official frost depth for your area. You can also find reliable maps online. Do not guess or assume based on a neighboring town.
Once you have your frost depth—let’s say it’s 42 inches—you need to choose a screw that allows the helix to be well below that mark. A 60-inch (5-foot) screw would be a safe choice, giving you plenty of buffer. Buying a 48-inch screw would be risky. Always err on the side of going longer. A screw that’s too short is useless for preventing heave.
Ultimately, ground screws offer a smarter, faster, and more durable foundation for nearly any structure on your property. By matching the right type of screw to your project and, most importantly, the right length to your climate, you can build with confidence. You’ll spend less time fixing what the winter broke and more time doing what you love.
