A holiday park development in stunning Scottish woodland

Sustainable foundations as an alternative to concrete

These beautiful 40-foot luxury holiday lodges overlook the stunning 16th-century Thirlestane Castle. Due to the woodland location and the client’s respect for the surrounding environment, ground screw foundations provided a low-carbon and efficient alternative to traditional concrete bases.

Each lodge’s steel chassis needed a specific ground screw anchor layout with bespoke pads to align accurately with jacking points on the underside. It was critical that these were correctly specified and positioned, meeting both the engineer’s and manufacturer’s requirements.

Foundation screws with eye bolts were installed to provide the tethering points with adequate tensile capacity, securing the lodges in place and preventing any uplift from strong winds.

Site Survey & Load-Testing

Compiling a full report, we attended the site to complete pre-installation surveys, including axial, lateral, and tensile load-testing, providing the empirical data required by the project engineers.

Bespoke Base System

We designed and manufactured bespoke foundations to interface between ground screws and each lodge, meeting the lodge’s manufacturer and installer requirements.

Ground Screw Installation

Efficient installation was achieved with our range of powerful ground screw machines driving 1.2m and 2.0m RADIX Ground Screws to their load-bearing capacities, including our hydraulic rig, REX.

The foundations for log cabins were completed within a day, allowing for swift installation of lodges to continue with minimum environmental impact.
