STOP DIGGING’S SCREWS REPLACE CONCRETE FOUNDATIONS –
WHAT ARE GROUND SCREWS?
Concrete blocks or screws? There’s no need to ask: There’s a ground screw for every project. Beam screw, post screw, adapter screw and pipe screw – we have four basic models of screw with different brackets, lengths and measurements depending on what is to be anchored, what the load requirements are and the ground conditions where the screws are to be installed. As well as all this, we have a number of attachments for special installations. Where you need a concrete supporting block, we can install a screw!
OUR SCREWS AND ATTACHMENTS
WE HAVE THE GROUND SCREWS FOR ALL YOUR NEEDS
SGC ADAPTER SCREWS

FAQ – COMMON QUESTIONS
Ground screws – how, where and when?
We have the answers.
Each construction project has unique conditions and requirements, but our ground screws are versatile and make it possible to stably anchor projects large and small. If you don’t find the answer to your question here, don’t hesitate to contact us.
01 Ground screws - why?
Ground screws from Stop Digging provide stable ground anchorage that saves both time and money. Ground screws or earth screws make your construction project easier: you don’t need to carry heavy concrete support posts or mix concrete, or spend a lot of time and effort digging and then restoring the surrounding ground. If you cast concrete, then you also have to wait for it to harden. The ground screws can be mounted all year round, even in frost, and work in most soils. The screws are installed quickly, and you can use the foundations immediately.
Stop Digging’s ground screws should not be confused for the type of ground screw or anchor sold at DIY stores. Stop Digging’s innovative ground screws are always delivered with complete installation by our certified installers.
02 Stop Digging's customers
We carry out work for both private individuals and companies, and all our fitters are certified. We have, among other things, delivered foundations to NCC, Skanska, Peab, Riksbyggen and several municipalities around Sweden.
03 Ground screws - when?
Ground screws can be used as a foundation in both private and public projects. A foundation using earth screws is suitable for patios, park benches, rubbish bins, signs, fences, noise barriers, screens for rubbish bins, recycling storage sheds, bicycle storage and much more. We have smart solutions and lots of ways to work with specific projects. If you have a project we have the ground screws for it!
04 Ground screws - how deep?
How deep the ground screws need to be anchored depends on the load and the prevailing ground conditions. Our screws come in lengths from 580mm to 2500mm, to be able to create stable foundations in most soil types and construction projects. We help you choose the right screw for each project and location.
05 Ground screws - how long?
The length of ground screw you need varies depending on the soil condition, load and of course what type of project it is. We have four different types of screw – adapter, pipe, pillar and beam screw. These come in various lengths and dimensions to be able to meet all your requirements. As well as this, our ground screws have a number of specially designed attachments for different types of specific installations, such as flagpoles. All our earth screws are made for our Nordic climate with dimensions adapted to Swedish construction standards.
06 Ground screws on rocky ground?
We always pre-drill a test hole before installing the ground screws. Smaller rocks are pushed away by the pre-drilling, medium-sized rocks get broken down. We have different solutions depending on the situation that arises. Our authorised fitters receive thorough training and have vast experience of solving problems.
If there are rocks where you are going to build, there is a good chance that our installers can drill holes in the rock and anchor with a steel stud or steel post bracket. If your building, for example a wooden deck, is partly over a rock, we investigate the solution on-site, and make decisions on a case by case basis. In newly excavated soil, we need to take extra account of any subsidence in order to be able to perform a good and stable installation of ground screws, by choosing a longer screw, for example.
Our ground screws work excellently even on steep slopes where you might want to anchor, for example, a staircase, build a terrace or install play equipment. Stop Digging’s screws are available in different lengths and together with our attachments, including plates and L-support, we can perform many types of special installation.
07 Ground screws during a frost?
We can install ground screws all year round. Depending on the how deep the ground frost penetrates, there might be an additional step needed in the installation process which can add an extra cost. Our earth screws are specially developed to withstand harsh conditions and the Nordic climate. Do you want to find out more? We are happy to help you with more information and reference projects.
08 Ground screws - strength?
Our ground screws are made of ISO 630 FE 360 steel and the wall thickness and surface coating are specially developed and adapted to the Northern climate. All our earth screws are hot-dip galvanised according to ISO 1461. All products are CE certified and manufactured in accordance with EN 1090-1: 2009. Our production facilities are also ISO certified in accordance with ISA 9001. Our screws have an expected lifespan of at least 100 years*.
*Stop Digging stipulates an estimated minimum lifetime for its ground screws. The amount reflects the number of years an installed screw is expected to fulfill its technical purpose under normal conditions, and is based on many years of experience and research.
09 Ground screws - subsidence?
In the same way as concrete foundation posts, the ground screw can also be affected by subsidence in the ground, but our steel ground screws are generally not affected by frost. In newly excavated soil, we need to pay special attention to this in order to be able to perform a good and stable installation of ground screws, for example, by choosing a longer screw.
10 GROUND SCREW LOADS
All our earth screws are thoroughly tested to meet load, pressure and tension bearing requirements. Read more about our screws here. These values are the result of a number of tests in different soil types and can be affected by different soil conditions. To ensure local values, we can perform a tensile test.
11 GROUND SCREW CERTIFICATIONS
Our steel earth screws are specially developed, and the thickness and surface coating has been adapted to the Northern climate. All our earth screws are hot-dip galvanised according to ISO 1461. They are CE certified and our production facilities are ISO certified in accordance with ISO 9001.
12 Ground screws - cost?
We offer a fixed price according to a quote. However, our prices vary depending on which ground screw you need to use and where in the country you are. All projects have unique requirements, and the price will reflect this. Contact Stop Digging for a free quote.

INSTALLATION EVERYWHERE, ALL YEAR ROUND
GROUND SCREW INSTALLATION – HOW IT WORKS
Before installing the screws, all holes are pre-drilled to make the screws easier to attach. The pre-drilling also gives us an idea of the prevailing soil conditions so that we can choose the right length and location of each screw. Our technology can handle all types of soil – compact clay is not a problem, and smaller rocks can move or crack. If we encounter large stones or rocks, we can either adjust the location of the screw or put a stud in the stone. In porous soil or sand, we use our longest screw.
Installation is quick and easy, it only takes a few minutes per screw. The ground screws are installed with the help of our specially developed machine which has extremely high torque. It can even install screws when the ground is covered by frost. The machine does not damage grass or other surfaces. If you need a foundation built in an area covered by cobblestones, we just lift a stone and drill. Similarly, if there is asphalt we can easily make a nice tidy hole for the screw.
*Stop Digging stipulates an estimated minimum lifetime for its ground screws. The amount reflects the number of years an installed screw is expected to fulfill its technical purpose under normal conditions, and is based on many years of experience and research.
