Our product range
The E-series ground screws can be optionally equipped with an excentre set depending on the application. The excentre set allows you to make precise adjustments and ensures a perfect, vertical positioning of the object that you want to install. The system is particularly suitable for the resonance and vibration dampening installation of poles and masts for example.
The F-series ground screws are equipped with round or square flanges. The fixation of the bearing object made possible by this ensures the highest possible stability and safety, even with large or extreme structural loads.
The G-series ground screws are equipped with either one, three or four threaded screws. They are ideally suited for the quick, vertical and permanent installation of masts and fence posts, for example. Optionally, the fence posts, for example, can also be quickly and permanently fixed into place with the special granulate.
The M-series ground screws have a centred M-thread which allows the object that is to be carried to be directly screwed onto the ground screw. They are particularly suitable for constructing prefabricated garages and containers, for example.
The U-series ground screws have been specially designed for all regularly-dimensioned timber beams. They are perfect for the simple and fast mounting of horizontal and vertical timber beams, for example during carport and wooden terrace construction.
Our V-series ground screws are extendable. The ground screws can be extended according to the project requirements and were specially developed for projects with high loads. The products V89, V114 and V140 come with DIBt-approval.
The X-series ground screws were developed for special applications. This product can be used to produce made-to-measure foundations. The screws are tailor-made individually according to construction requirements.
The advantages of Krinner ground screws
Eco-friendly
Our ground screws don’t harm the environment during installation or after use. No soil needs to be moved for the installation and the foundations can be removed without leaving behind any residue.
Efficient
The installation process is significantly faster than that of traditional foundation solutions. Individual foundations can be created in just a few minutes and house foundations take just a day to be put in place.
Safe
Based on the thousand-year-old pile foundation principle, ground screws offer a safe and secure foundation solution. They can carry the same load as some conventional concrete foundations.

Why is the soil a decisive factor in foundation construction?
Why is the soil a decisive factor in foundation construction?
Natural soils
Our prevalent soil type is known as natural soil. It’s usually made up of both organic and non-organic components. Organic soils are formed during the natural decomposition process. Humus, turf and moor-like soils fall into this category and usually have a high water content and low oxygen content. On the contrary, non-organic soil elements are rather water-permeable and rich in oxygen and are produced through rock weathering. These include gravel and small-grain sand, as well as limestone, gypsum and clay. If there is a mixture of sand, clay and silt this is known as loam. If you mix clay and limestone, you get marl. Natural soils can consist of a mixture of these components, either accumulated naturally or having been poured. Whether a natural soil is capable of bearing a load or not depends on its mixture ratio and on the thickness of the bedding.
Evaluation of the load-bearing capacity
When it comes to the load-bearing capacity of the soil, it is important to differentiate between cohesive and non-cohesive soils. Cohesive soils primarily consist of loam, silt, clay or limestone. A characteristic of cohesive soils is that they are capable of absorbing large quantities of water which, when combined with the tendency of individual particles to adhere to each other, often results in the soil turning into mud. A state that significantly reduces the soil’s load-bearing capacity and therefore makes it unsuitable for construction. However, when they are dry cohesive soils can have an excellent load-bearing capacity. On the other hand, when non-cohesive soils are packed tightly they have an extremely high load-bearing capacity. In general, they consist of sandy and gravelly components and are permeable to water and air. In between these two categories there is also weakly-cohesive soil, which is more or less a combination of the two other soil types. Alongside the load-bearing capacity, the corrosivity of the soil also plays an important role.
