The installation of screw foundation piles is silent and vibration-free, which marks a revolutionary change compared to traditional foundation methods. Noise levels during installation do not exceed 65 dB at a distance of 10 meters from the work site, which corresponds to the level of normal conversation. These characteristics translate into specific benefits for investment projects:

• The possibility of working in densely built-up areas without disturbing residents

• No time restrictions arising from noise regulations

• Protection of existing structures from vibration-related damage

• Improved working comfort for operators and nearby residents

Manual installation

Manual installation is used in projects with limited access, small loads, and situations where heavy equipment cannot be used. Special lightweight, handheld screwing devices are applied, capable of generating sufficient torque. This method is particularly popular for:

• Terrace and veranda foundations

• Renovation works in existing buildings

• Projects in hard-to-reach locations

• Temporary and lightweight structures

Hydraulic machine installation

Machine installation of screw foundation piles uses advanced hydraulic systems mounted on various platforms:

• Mini-excavators and self-propelled units are the most commonly used platforms for all projects. Equipped with hydraulic torque motors of up to 12 kNm, they offer:

  • Precise depth and angle control

  • Ability to work in confined spaces

  • Integrated torque monitoring systems

  • Integrated GPS positioning systems

  • Automatic control of installation parameters

  • Integrated documentation systems

  • Productivity of 15–20 piles per day

  • Capability to work with piles up to 168 mm in diameter

Screw foundation piles can be installed practically all year round within a temperature range of -10°C to +30°C, which is a significant advantage over traditional foundation methods. This versatility results from several key factors:

• Resistance to weather conditions

• No need for concrete curing eliminates frost-related limitations

• Steel structure retains mechanical properties across a wide temperature range

• Installation process does not require antifreeze additives or special protection

Soil conditions in winter:

• Ground freezing up to 80–120 cm does not affect pile installation reaching depths of 3–10 m

• Lower water content in soil during winter may facilitate penetration in certain soil types

• Stable ground in frost periods provides better conditions for heavy equipment

Construction schedule optimization:

• Ability to continue foundation work regardless of the season

• Use of periods with lower demand for construction services

• Shortening overall project execution time by up to 70%

Installation without spoil means no need for soil removal, which translates into:

• Zero amount of soil waste requiring disposal

• Cost savings on transport and storage of spoil

• Preservation of natural soil structure around the foundation

• Minimal interference with existing infrastructure and greenery

The installation of about 60 meters of pile per day is a standard efficiency for experienced teams, although it will vary depending on the chosen installation method and equipment used.

Efficiency parameters by equipment type:

• Manual installation: 10–15 meters/day (piles up to 140 mm, depth up to 5 m)

• Mini-excavators and self-propelled units: 30–60 meters/day (piles up to Ø168 mm, depth up to 12 m)

Factors affecting efficiency:

• Soil type: rocky soils and those requiring pre-drilling significantly reduce efficiency

• Installation depth: piles up to 5 m – maximum efficiency, above 10 m – reduction up to 25%

Access conditions: spatial limitations may reduce efficiency by up to 20%
