IE GSI Geotechnical Data Ireland ITM Map

Geotechnical Site Investigations and boreholes provide vital information on the ground beneath our feet. The information helps to find out the nature of the ground and can help spot any hazards.

Engineers need this information when they are building structures (houses, buildings, roads, etc.). They need to know the quality of the ground: the strength and depth of soil, if there is rock and if there is groundwater. They can then decide how best to build the structures so that they don’t collapse. They can also find out if there are any underground obstructions, groundwater, faults etc which could result in extra costs or delays.
