Our services

What We Install

From site surveys to full installation — we handle every stage of your ground screw foundation project.

01

Site Surveys & Ground Testing

Before any screws go in, we assess your site. We carry out ground resistance tests and load calculations to specify the right screw size and spacing for your project — giving you confidence before you commit.

Includes soil resistance testing, load calculations, and a written specification report.

02

Ground Screw Installation

We supply and install RADIX ground screws for projects of all sizes. Our machine-driven installation is fast, precise, and leaves your site clean. Most residential installations are complete in a single day.

Suitable for garden rooms, log cabins, home extensions, decking, fencing, and more.

03

Bespoke Subframes

We design and install custom timber or light gauge steel subframes to sit on top of your ground screws — giving your builder a level, ready-to-build platform from day one.

Available in treated timber or galvanised light gauge steel. Designed to your project spec.

04

Solar Racking Systems

Ground-mounted solar arrays need foundations that are perfectly aligned and built to last. We install solar racking systems using ground screws — no concrete, no groundworks, no delays.

Suitable for domestic and commercial solar arrays. Laser-aligned for precision.
