Add our helical piles for challenging soils — peat, soft clay, organic soils, frost-affected ground — where standard C-profile won’t hold. Solar projects across Europe.
Talk to usTreat the foundation as a secondary item on challenging ground and it shows — racks tilt, modules break. When the foundation moves, the rack moves — and the bid you won becomes a warranty case carried by the EPC, traced back to the racking spec.
Helicasol piles are engineered for exactly this ground. The helix plate sits below the weak surface layer, anchored in stable load-bearing soil. Length, diameter and helix size are sized site-by-site for each soil — co-designed with your bracket geometry so your racking stays calibrated season after season.
Soft, peaty, frost-prone sites others can’t bid — you can. Same racking system, more sites won.
On peat, organic soils, soft clay or high water tables, the standard rammed C-profile post often can’t carry enough load. Even when a site looks fine on paper, your bracket can lose the bid if the foundation cost is too high. Helicasol helical piles are designed for exactly these soils, sized pile-by-pile to the actual ground. Sites your racking would otherwise lose are now buildable.
Your standard rammed C-profile post serves many of your sites. But on challenging soils — soft peat, organic soils, or frost-affected fill — friction-dependent designs simply won’t hold. The site passes the desk study — then your racking gets dropped in EPC bidding because the foundation maths don’t work.
Where rammed C-profile can’t hold, helical piles do — capacity from helix bearing and shaft friction together, sized pile-by-pile to the actual ground. Add them to your standard package as the foundation line for tough sites. Your racking, your bid to the EPC, our piles in the ground — the site is buildable, the order is yours.
Helical piles need a different pile-to-frame fitting than your standard rammed-post bracket. It’s real engineering — but a detail next to the main fix. Co-engineered with us, or built by your metalwork team using our pile-side specs. Whoever holds the pen, the connection works.
Same racking. Same EPC bid. Now buildable on ground that would otherwise lose you the order.
Helical piles sized to your racking and the site’s actual ground — built into your offer to the EPC, not bolted on after.
First we sign an NDA — no data is shared before that. Then you send us the racking drawings and the load on each post. We also need the ground survey data and a site plan, usually provided by the developer or EPC. Without the ground data, we cannot size the pile.
We size the helical piles for your loads and the actual ground, and verify the capacity by testing when needed. The bracket — the pile-to-frame connection — is designed either by us, together with you, or by your own team from our pile-side specifications. You decide.
We manufacture the helical piles in-house at our EN 1090 Exc2 facility — brackets too, when engineered by us. One source, one quality standard, one accountable supplier.
Your racking gets the order on sites nobody else can serve.
71,000 PILES · 9 M PEAT
Joroinen · 129 MW / 200 ha
Finland’s second-largest solar park. 71,000 helical piles installed for tracker structures across 200+ hectares of soft peat — bracket-engineered to the developer’s racking system.
2P TRACKER STRUCTURES
Ypäjä · 1.5 MWp 2P trackers
Complete foundation scope for 1.5 MWp of 2P tracker structures. Demonstrated helical performance under tracker-specific loads in demanding winter conditions.
58 MEASUREMENTS · 3-ZONE STRATEGY
Ground testing & piling
Three-day campaign across soft clay and variable ground. 58 measurements produced a three-zone foundation strategy — bracket-engineerable for any racking system.
2-SIZE PILE DESIGN · ~80% COVERAGE
Ground testing & piling
Three-day evaluation across fields and bog. Identified stony layer at 1.5–2.5 m depth and produced a two-size helical-pile design covering ~80% of the area — bracket-engineerable for any racking system.
