Ground Investigation in Co. Waterford

Ground investigation is one of the most important aspects of the design stage for any building.  It can identify concerns early, particularly those which may have high costs implications. Dynamic probing is a relatively quick and easy method to get a preliminary assessment of the ground conditions well in advance of construction. Our rig is small and compact and can access areas with widths of less than one metre.

On this project, we were asked to complete some dynamic probes and soil samples with an interpretative report for a small development in a seaside town in Co. Waterford. Six number dynamic probes and one number windowless sample was employed across the site at locations set out by the consulting engineer.

As one part of the development comprised of a four-storey building, the requirements for the resistance of the soils were approximately 800kN/m2. Although the preliminary design allowed for a large ground supported rc pad at shallow depths to accommodate such loads, the logs showed that such foundations would have to be formed at depths of greater than 2 metres. As this approach was considered impracticable and considering the requirement to retain various structures across the site, a micropiled solution was the only viable option.
