Six steps from project brief to the correct pile specification. Covers project types, soil conditions, load requirements, and the right product series for your needs.
Your project type determines the load class, installation method, and product series you need. Identify your project category below to narrow your selection immediately.
Solar parks, BESS installations, substations, powerlines, 5G masts, pipelines. High volume, verified load capacity per pile.
Warehouses, halls, modular buildings, noise barriers, platforms, retaining walls. Structural loads requiring engineering design.
Houses, extensions, garages, holiday cabins. Permanent structural foundations designed to meet local building codes.
Terraces, decks, fences, garden rooms, jetties, small sheds, greenhouses. Lighter loads, hand or small machine installation.
Peatlands, wetlands, flood zones, slopes, remote sites with limited access. Projects where concrete is impractical or impossible.
Road portals, rail gantries, signage, lighting masts, EV charging stations, advertising structures, boardwalks.
Soil type directly affects bearing capacity, required pile depth, and helix configuration. The most reliable basis for pile selection is a geotechnical survey. If you have soil data, send it to our engineering team for a project-specific recommendation.
The helical flange cuts through and anchors in clay effectively. Good bearing capacity at moderate depths. Multiple helices can increase capacity in stiff clay.
Dense sand and gravel provide immediate resistance. Screw piles achieve high torque values quickly, confirming reliable bearing capacity at shallower depths.
Screw piles pass through soft layers to reach firmer soil below. Longer piles may be needed. Paalupiste has extensive experience with solar parks and boardwalks on peatlands.
Mixed soil with variable grain sizes. Screw piles handle moraine well, but installation torque should be monitored to detect obstructions like larger boulders.
No soil data? Contact us with your project location and planned structure. Our engineers can advise on typical soil conditions in your area and recommend a starting specification.
Every pile must carry the loads imposed by your structure safely. Screw pile sizing starts with understanding what forces the foundation will need to resist.
Structural calculations required. For projects requiring building permits, a structural engineer must calculate the loads and specify the pile size. Our engineering team provides pile design and load tables tailored to your project.
Paalupiste manufactures two product series. Your choice depends on load requirements, installation method, and project scale.
Machine-installed piles for structural and industrial applications. Designed for high-load projects including buildings, solar farms, substations and infrastructure.
2nd generation screw pile with cast steel head for effortless manual or machine installation. Fences, jetties, garden rooms, terraces and small cottages.
Three parameters define the pile specification: tube diameter, helice (helix plate) diameter, and pile length. Each is selected based on your load requirements and soil conditions.
Determines the pile's structural strength and lateral resistance. Larger tubes handle higher loads and longer unsupported lengths above ground. PRO range offers 9 standard sizes from 60.3 to 323.9 mm.
Controls the bearing area in the soil. Larger helices provide higher compression and tension capacity per plate. Multiple helices can be added to increase capacity without increasing pile length.
Must reach the load-bearing soil layer. Soft ground requires longer piles; firm ground allows shorter ones. Extension sections can be added if the bearing layer is deeper than a single pile length.
Single helix is standard. Additional helices increase both compression and tension resistance, especially useful in cohesive soils like clay. Reduces the required pile length for equivalent capacity.
Need help with sizing? Send us your soil data and structural loads. Our engineering team will provide a pile specification including tube diameter, helice size, pile length, and installation torque targets.
The correct installation method ensures your piles achieve the designed load capacity. Choose based on your pile series and site conditions.
PRO series piles require a hydraulic drive head mounted on an excavator. The drive head rotates the pile into the ground while the operator monitors torque values in real time.

HELIX series piles can be installed manually using a crowbar or with one of our electric pile drivers. Mini excavator with a small drive head is also an option for larger quantities.

Use this table to identify the right starting point based on your project type. For precise specifications, contact our engineering team with your soil data and structural loads.
These are typical starting points. Final pile specifications depend on your actual soil conditions, structural loads, and local building regulations. Our engineering team provides project-specific recommendations free of charge.
