Screw pile cost: what drives the price?
Five factors shape every quote: ground conditions, pile size, quantity, site access, and working space.
What affects screw pile cost
Seven variables determine the per-pile and total project price.
-
Pile diameter and wall thickness Larger diameter piles carry heavier loads but cost more per unit. The shaft diameter typically ranges from 60.3 mm to 168 mm.
-
Pile length Longer piles reach deeper bearing strata but require more steel. Screw piles often reach capacity at shallower depths than driven piles, reducing material cost.
-
Number and size of helices More helices or larger helix diameters increase load capacity and cost. Single-helix piles suit lighter loads; multi-helix designs handle higher demands.
-
Soil conditions Soft clay, peat, or sand each require different pile configurations. A site with good bearing soil may need shorter, simpler piles.
-
Hot-dip galvanization All Paalupiste piles are hot-dip galvanized to EN ISO 1461 for 50-100 year service life. This is included in the product price.
-
Number of piles Volume matters. Larger projects benefit from better per-unit pricing. A garden shed needs 4-6 piles; a solar park may need thousands.
-
Installation method HELIX piles can be installed by hand drill (lower cost, ideal for DIY). PRO piles require an excavator-mounted drive head (faster, suited for larger projects).
PRO vs HELIX: two pricing tiers
HELIX is Paalupiste's hand-installable range for residential and light commercial projects - decks, fences, sheds, small buildings. Lower cost per pile, no heavy equipment needed.
PRO is the professional range for commercial, industrial, energy, and infrastructure projects. Larger diameters, higher load capacity, machine-installed. Higher cost per pile, but the per-unit cost decreases with volume.
Screw piles vs concrete: where the cost goes
The pile itself is one cost line. Site preparation, equipment, labour, and timeline are the rest.
| Cost Factor | Screw Piles | Concrete Foundations |
|---|---|---|
| Excavation | Not required | Required - excavation + soil disposal |
| Formwork | Not required | Required - materials + labour |
| Curing time | None - instant load capacity | 28 days for full strength |
| Frost protection | Not required | Usually required - insulation + materials |
| Drainage | Not required | Usually required - design + installation |
| Labour hours | Low - single-step installation | High - multiple trades and phases |
| Equipment | Excavator or hand drill | Excavator + concrete truck + pump |
| Total project time | Hours to days | Weeks |
| Removal cost | Low - fully removable and reusable | High - demolition required |
| Overall | Lower in most cases | Higher in most cases |
Cost by application
Different load classes, different pile spec, different cost profile.
Residential & DIY
HELIX RangeDecks, fences, sheds, garden rooms, small cabins. HELIX piles are hand-installable with a standard drill, eliminating heavy equipment costs. Ideal for homeowners and small contractors who want professional-grade foundations without the concrete budget.
Commercial
PRO RangeWarehouses, modular buildings, retail units, car parks. PRO piles are machine-installed for speed and consistency. Mid-size projects benefit from fast project delivery and reduced site preparation costs compared to concrete alternatives.
Industrial & Solar
PRO RangeSolar farms, BESS installations, industrial halls, infrastructure. Large-scale projects see the biggest cost advantage from screw piles: volume pricing, minimal site prep, and installation speeds that can deliver hundreds of piles per day.
