INSTALLATION

Machinery, matched to the ground

Our own crew and machines turn the piles into the ground and get you building fast — the structure is set the same day.

The field log / 01—05

Built in five moves.

Every installation is measured, verified, and ready for the next trade the same day. Follow the work from first soil reading to final torque record.

Subsoil Evaluation

Geotechnical survey assesses soil composition, load-bearing capacity, layer structure, and corrosion potential to ensure optimal foundation design.

Foundation Planning

Using soil data, load specifications, and structural analysis, we select the appropriate groundscrew type and exact quantity needed.

Load-Bearing Capacity Test

Tension-compression tests validate the structural design and determine the minimum installation torque required on site.

Installation & Documentation

Skilled operators install with electric or hydraulic drivers. Torque at each position is recorded and loads can be placed immediately.

Dismantling Option

For temporary projects, groundscrews can be unscrewed, reused if undamaged, or sustainably recycled. Site restoration stays simple.

Matched to the ground

Foundation performance depends as much on the installation rig as on the pile. We size the rotary drive head to the torque demand of the site's soil profile and mount it on a carrier. Design starts with the geotechnical report, or with a verification pile where no report exists. Carrier, drive head and helix diameter are then selected as per the terrain.
