The GSI has been making efforts to input all available site investigation reports, borehole and trial pit records to the national geotechnical borehole database, both for the Geotechnical viewer and the GeoUrban project. The Geotechnical viewer includes all the investigations held for the whole country. Soil types and Depth to Bedrock (DTB) data is frequently recorded which contributes to revised quaternary mapping. Depth to Bedrock and Rockhead maps are updated when new data is available.
These maps are available to view and query on the GeoUrban Viewer.
There are also Depth to Bedrock and Rockhead maps from other towns (Galway, Limerick and Waterford).
