Geotechnical Consultancy

IGSL offers advisory and consultancy services in geotechnics and engineering geology. Our aim is to provide practical and ‘buildable’ solutions and with over 30 years experience in geotechnics (Ireland, UK, France, Belgium and Jamaica) we provide value engineered and sound geotechnical solutions. We have a team of five chartered geotechnical engineers and two professional geologists.

Geotechnical Interpretative reports (GIR’s) have been undertaken for large pharmaceutical projects (e.g. Amgen, MSD Carlow, Regeneron Limerick), food process plants (Kerry Foods, Glanbia), wind farms (Mainstream Renewable Power, Enercon, Bord na Mona, Siemens) and a range of large infrastructure projects (i.e. hospitals, schools, roads, bridges, water, sewerage and reservoirs).

We carry out temporary works and ground retention design for deep excavations (e.g. Intel Fab 14 & Fab 24, Indaver Waste Management Duleek, St Vincents Private Hospital), soil and rock slopes (e.g. Laraghcon Lucan, N69 Limerick, N4 (Drumsna) and piled foundations (e.g. Intel Fab 24, Abbott Sligo, MSD Carlow, Arcelor France).

Earthworks assessment and compliance testing on site won or imported fill is a key part of our geotechnical consultancy services. We have the capability to provide on-site testing of earthwork materials including lime or cement stabilized fill. We provide a wide range of earthworks testing and advisory services and recent high profile projects include MSD Carlow, Grifols City West, Glanbia Belview and Alexion College Park.

IGSL provides expert witness services and Dr George Matheson is exclusively retained for his expertise in petrography and assessing hardcore aggregate for pyrite induced swelling.
