GEI was founded as a geotechnical engineering firm in 1970. Since then, GEI has been a consistent industry leader in this space and has increased servicing offerings to include hydrogeological, environmental and materials testing and inspection fields.

GEI takes a holistic view of the engineering behaviour of earth materials, including soil, rock and groundwater. Whether it is for earthworks, buildings, structures, or developments, it is imperative to understand how these earth materials work with each other. This understanding enables you to develop the right design when building on top of, building below, or building with these earth materials.
