Answers to questions clients ask about screw piles and their installation.
Screw pile systems and sales
We offer screw pile solutions for various applications, tailoring the selection to the type of structure, soil conditions, and expected loads. The screw piles are chosen based on both functional requirements and structural characteristics to ensure safe and long-lasting foundation construction.
High-quality material: We use Q235B carbon steel,
which is hot-dip galvanised—ensuring strength and durability in accordance with the DIN EN ISO 1461 standard.
Average zinc coating thickness: 70 μm (microns).
Screw piles by application
Different screw pile solutions are used to adapt to soil conditions, terrain, and technical requirements.
- Standard support screw piles
- Reinforced load-bearing screw piles
- Screw piles with extensions for deeper layers
- Adjustable solutions for height correction

Screw pile installation on site
Montāžu veicam objektā, nodrošinot skrūvpāļu precīzu ieskrūvēšanu un līmeņošanu atbilstoši plānotajai konstrukcijai. Strādājam ar profesionālu elektrisko rokas reduktoru, kas ļauj montēt arī vietās ar ierobežotu piekļuvi un nebojājot teritoriju. Pamati pēc montāžas ir gatavi turpmākai būvniecībai tajā pašā dienā.
What is included in the installation
- Marking out the pile positions and installation
- Levelling of heights and preparation for fixing
- Basic inspection and handover for further works
What is required on site and what the client should consider before work begins
- The client must ensure that they have all necessary rights and permits to carry out construction works on the specific plot.
- A decision on the location of the structure must be made in accordance with applicable regulations, taking into account possible underground services within the screw pile installation zone down to approximately 2 m depth (electric cables, drainage, water supply, gas pipeline, etc.).
- A sketch or project must be agreed with us and the builders, indicating foundation dimensions, types of screw piles, lengths, and required quantities.
- Access to the installation site must be ensured, and it is recommended that the site is prepared (cleared of trees, bushes, tall grass, and other obstacles).
- A 220V power supply must be provided (if not available, an alternative solution can be arranged).
Bespoke solutions
Non-standard solutions
Not all sites are the same—terrain, soil conditions, and site access often require an individual approach. In non-standard cases, screw piles allow the foundation solution to be adapted to the specific situation while maintaining stability and precision.
When non-standard solutions are required
- Sites with uneven terrain or on slopes
- Structures near water—walkways, piers, shoreline constructions
- Areas with limited access where heavy machinery cannot be used
- Constructions requiring non-standard heights or support spacing
What solutions are used
- Screw piles with extensions to reach load-bearing soil layers
- Adjustable fixings for height correction and precise levelling
- Individually adapted pile layout according to loads and structure
- Work with handheld equipment in areas where mechanised installation is not possible

Frequently asked questions
Hot dipped galvanised steel provides over 50 years of service life. We use Q235B carbon steel with an average zinc coating thickness of 70 μm according to DIN EN ISO 1461 standard.
A standard screw pile load capacity ranges from 1 to 4 tonnes depending on diameter, length, and soil conditions. We determine the exact capacity for each project during installation by monitoring torque.
Screw piles are installed in one day, without excavation, curing time, or damage to the surrounding area. The foundation is ready for load immediately after installation. Screw piles can also be removed if needed.
The client needs to arrange construction rights and permits, know the location of underground utilities up to 2 m depth (cables, sewage, water, gas), and provide a 220V power supply. The site must be cleared of trees, bushes, and tall grass.
For private houses and terraces, screw piles are typically installed 1.5 to 3 metres deep. The final depth depends on soil conditions. We drive the pile until the blade reaches a load-bearing soil layer and torque shows the required resistance.
The main differences are metal thickness, zinc coating quality, and weld execution. Cheap screw piles often have thinner shaft walls and incomplete corrosion protection, which accelerates rust. Quality screw piles are hot dipped galvanised according to DIN EN ISO 1461 with an average coating thickness of 70 μm.
Foundation installation for a private house or terrace typically takes one working day. Larger projects or complex soil may require two days. After installation, the foundation is ready for frame construction without any waiting period.
