For more demanding projects, you get a complete foundation solution: soil investigation, pile design, manufacturing, and installation, all coordinated through one supplier.
Expertise That Works for You
25 years across different soils and project types. That means your foundation performs as designed and your schedule stays on track.
The Result Matters
Whether you need piles delivered or a turnkey foundation, the outcome is the same: a foundation that lasts, a schedule that holds, and a site that runs smoothly.
A Quarter Century of Helical Piling
The very first pile. Installed by hand. 2001.
Manufacturing Begins
Helical pile manufacturing started in Finland with a simple idea: foundations should not need concrete, excavation, or weeks of waiting. The very first pile was installed by hand.
First Piling Machine
An old soil investigation rig was adapted to install helical piles. This made it possible to take on real construction projects and move beyond hand installation.
Excavators Take Over
Trials with different installation methods showed that excavators were far more efficient than crane trucks. This insight shaped the installation approach still used today.
First Large-Scale Project
The first large-scale project delivered several hundred piles for a plant nursery, proving that higher volumes and more demanding jobs were well within reach.
Own Motors & First Export
To solve the problem of sourcing reliable rotary motors, the group began manufacturing its own. The same year saw the first international delivery, to Congo.
Into Hardware Stores
DIY helical piles reached Finnish hardware stores, giving private builders a simpler alternative to concrete. Sales grew quickly and soon expanded into Sweden.
New Facility & First Agent
Operations moved to a larger production facility. International growth began with the appointment of the first certified agent in Sweden.
Railway Infrastructure
Foundation solutions for railway infrastructure began. A road-rail excavator was acquired to enable efficient installations along rail tracks.
Projects in Germany
Projects were delivered in Germany, strengthening the ability to operate internationally with mobile equipment and experienced teams.
Belgium & UK
New certified agents joined the network in Belgium and the UK, supporting growth across key European markets.
Czech Republic & Iraq
Two major international projects marked a milestone: rail foundations in the Czech Republic and foundation solutions for an oil refinery in Iraq.
HELIX Product Line
The HELIX product line was launched, offering improved DIY piles with better usability and durability. The new series quickly gained popularity.
Spain & Italy
Demand for home and garden construction rose sharply and DIY pile sales grew. At the same time, operations expanded into Spain and Italy.
Portugal & Power Lines
Rotopile began operations in Portugal, bringing helical piles made in Portugal and Finland to the Iberian market. The group also started delivering foundations for electric power line infrastructure.
UK & Latvia
Two significant international projects were completed: a large electrical compound project in the UK and a 19,500-pile installation across wetland terrain in Latvia.
USA & New Markets
The group launched projects in Poland, delivered its first installations in the USA, and returned to Iraq for a new large-scale foundation project.
71,000-Pile Solar Park
One of Europe's largest helical pile projects began: a 129 MW solar park in Finland with over 71,000 piles. Interest from the energy sector kept growing, especially in battery energy storage (BESS) and power line foundations.
What Your Project Gets
From a single design consultation to full turnkey delivery with tens of thousands of piles.
Helical Pile Manufacturing
Your piles are manufactured at the group's production facilities in Portugal and Finland, under EN 1090, with high-quality structural steel and full material traceability on every order. The piles are available in two steel grades of your choice: S355/S420 structural and S550 high-tensile. Hot-dip galvanisation is available to EN ISO 1461. Standard sizes ship from stock; custom dimensions are produced to your project requirements with short lead times.
Certified Production
Your piles are produced in a facility that manufactures under EN 1090. All welding follows European structural standards, so you can trust that the piles match the design specifications.
Material Quality
Piles are manufactured from high-quality structural steel and are available in two grades: S355/S420 structural and S550 high-tensile. The steel is traceable from mill to finished product. Hot-dip galvanisation to EN ISO 1461 is available for long-term corrosion protection, even in aggressive soil conditions. Material certificates are available on request.
Standard and Custom Manufacturing
Standard pile sizes are available from stock for fast delivery. If standard sizes are not the best solution for your site, piles are manufactured to your project requirements. Lead times for custom orders are typically 2 to 4 weeks depending on volume. Whether your order is 20 piles or 20,000, you receive the same certified quality.
Quality System
The production facility operates under ISO 9001 (quality management) and ISO 14001 (environmental management). Every batch undergoes quality inspection before dispatch. Your delivery includes full material documentation, CE marking, and a Declaration of Performance.
Helical Pile Installation
An experienced installation crew comes to your site and ensures every pile is driven to the torque that matches the required load capacity. Typical installation speed ranges from 20 to 150 piles per day. The wide range reflects differences in soil conditions, site access, and pile size.
Experienced Installation Teams
Our installation crews have worked on projects ranging from a single residential foundation to industrial sites with thousands of piles. Your project benefits from field-tested methods refined over more than two decades and 2,500+ completed projects across Europe and beyond.
Torque Monitoring and Load Verification
Every pile is monitored with calibrated torque equipment during installation. The measured torque values are documented and correlated with the designed load capacities, giving your project a verified foundation performance record from day one.
How Installation Works
Helical piles are driven into the ground using hydraulic rotary heads mounted on excavators. The pile advances into the soil without vibration and without excavation. Your site stays clean, your neighbours stay undisturbed, and there is no concrete curing time. In most cases, the structure can be loaded immediately after installation.
Flexible Delivery Models
You can choose turnkey installation, or you can rent equipment and train your own team to install. Both options are fully supported with technical guidance and on-site assistance when needed.
Helical Pile Design
Your foundation is calculated according to Eurocode standards, taking into account the specific soil conditions and structural loads of your site. Our engineers support your project from initial feasibility assessment through to final pile layout and load verification.
Eurocode-Based Structural Design
All pile designs follow Eurocode 7 (geotechnical design) and Eurocode 3 (steel structural design), including the relevant national annexes. We provide load capacity calculations for compression, tension, and lateral loads based on site-specific soil data. The calculations document the factor of safety, pile spacing, and estimated embedment depth.
Site Assessment Support
When geotechnical survey data is available, our engineers recommend the right pile solution for your site. We always recommend a soil survey and are happy to help you get started if one is not yet in place.
Engineering Collaboration
We work directly with your structural engineers, geotechnical consultants, and project managers. Your team receives technical data sheets, installation specifications, and connection detail drawings to integrate into the overall structural design. All documentation is provided in formats compatible with your engineering workflow.
From Concept to Installation Plan
The design process covers everything from initial pile selection to a finished installation plan with coordinates, pile types, and target torque values. Clear documentation ensures smooth progress from design to installation.
Equipment Sales and Rental
Professional drive heads deliver torque up to approx. 150,000 Nm. Available for purchase or rental, with operator training always included. We help you choose the right unit for your excavator class and intended use.
In-House Drive Heads
The group's own brand of helical pile installation tools covers handheld electric drills, drive heads, extension booms, and adapters for machines and piles of all sizes.
Planetary Drive Heads
The full range of planetary drive heads is available, proven worldwide across tens of thousands of installations. Your equipment comes with full product support, spare parts availability, and technical assistance from the service team.
Handheld Equipment
For smaller projects and DIY installations, handheld installation tools let you install HELIX series piles without heavy machinery. Ideal for garden structures, decks, fences, and small buildings where excavator access is limited or unnecessary.
Rental and Purchase Options
You don't always need to buy. Short-term and long-term rental options are available for drive heads and other installation equipment. Rental equipment arrives serviced and calibrated, ready for your site. Operator training is included with both rental and purchase so your team can start working immediately.
