The private equity firm has taken a 30% stake in the business whose Geobind system strengthens ground for temporary and permanent works in a fraction of the time of traditional methods.
A growing number of main contractors are adopting it for the construction of access roads, highways, car parks and commercial buildings.
Geotech was established in 2014 by entrepreneur Bill Hinge and has been run by Hinge alongside fellow directors Robin Apperley and Dominick Holland.
Hinge said: “We have seen exceptional growth over the last two years, with our customers fully recognising the benefits of Geobind.
“The recent patent award, covering our Geobind system, highlights the uniqueness of what Geotech is undertaking within the stabilisation market.
“We are very happy that Mobeus shares our vision for Geotech, and this investment will enable us to take Geobind’s significant commercial, programme and environmental benefits to many more projects across the UK.”
