We design and manufacture screw piles with high load-bearing capacity, anti-corrosion protection, and installation precision for projects in Ukraine and Europe.
Engineering design of ground screw foundations considering site geology, structural loads, and project requirements. We calculate the type, diameter, and depth of ground screws, ensuring precise geometry and reliable performance of the foundation base.
MANUFACTURING
In-house production of ground screws with quality control at every stage—from steel selection to anti-corrosion protection. Products comply with design loads, durability requirements, and international operational standards.
INSTALLATION
Professional installation of ground screws with adherence to design geometry and controlled rotational torque. Foundations are installed without concreting or unnecessary earthworks, reducing implementation timelines and lowering costs.
Technical features of a ground screw
PILLAR ground screw is a new-generation screw pile made in the form of a steel pipe with specially designed blades. This engineering shape ensures easy and precise screwing into the ground without pre-drilling.

Types of Pile Heads (Connectors)
PILLAR manufactures two types of ground screws
With flange and without flange, which allows them to be used for connection with foundation elements of various shapes and materials.
Flangeless (Non-flanged)
Used for ground-based structures of solar power plants, with the possibility of universal connection to any type of grillage.
N - series
NC - series
Flanged
Used in foundations for residential construction, infrastructure facilities, industrial structures, hydraulic engineering projects, and carports.
FU - series
Fh - series
FS - series
FC - series

MODIFICATIONS of ground screws
ground screw with a drilling bit
Special nozzle on the cone
Suitable for soils with marl inclusions
Penetrates difficult layers: asphalt, brick, crushed stone, construction debris, rocky, dense, and frozen soils.
hermetic ground screw (painted)
Factory manufacturing without welding or concreting reduces the volume of installation work.
Feature: potential residual moisture inside the pipe, which creates a risk of corrosion.
Cost-effective solution — approximately 25% cheaper than galvanized piles.
ground screw with a root system (multi-blade pile)
Secure anchoring in the ground.
Branched base for better grip.
Effective compensation of horizontal forces
Suitable for complex conditions and loads
Increased bearing capacity and stability in weak soils
Sectional ground screw (Modular pile)
Adjustable length (6–12 m) depending on the soil.
Modular construction with sections connected during installation.
Joint strength equivalent to a monolithic pile.
For sites with limited overhead clearance.
Universal for various soils and loads.

Advantages of the HM-Series
PILLAR HM-SERIES ground screws are designed for objects requiring maximum reliability, high load-bearing capacity, and resistance to dynamic and wind loads. They are used in conditions of increased horizontal forces, where standard solutions do not provide the necessary stability.
Versatility
Reliably perform in sandy, marshy, and low-bearing capacity soils where traditional concrete foundations are ineffective.
Installation Flexibility
Flange connections allow for the use of either bolted or welded attachments—depending on the engineering design.
Anti-corrosion Protection
Hot-dip galvanizing provides long-term protection against corrosion and other negative environmental impacts.
Resistance to complex loads
An ideal solution for objects subject to wind, seismic, and dynamic loads: solar trackers, power lines, and wind turbines.
Reinforced design
Reflects increased steel thickness, providing rigidity and stability for high-load objects.
Rapid commissioning
Piles are ready for loading immediately after installation—without concreting or curing time. Installation is possible within a single day.
Maximum strength and rigidity
20 mm thick flanges with stiffeners (gussets), along with a forged tip, ensure foundation durability under significant loads.
Increased load-bearing capacity
A threading length of up to 4000 mm and a pile diameter of 168 mm ensure effective penetration and anchoring even in weak, peaty, and water-saturated soils.
Fields of application
Wind power plants, SES (fixed and tracker systems), power transmission lines, industrial facilities, tourism infrastructure, hangar structures, parking lots, and carports.
