The inclinometer probe descends into the borehole on a Kevlar cable, measuring lateral displacement millimeter by millimeter. We run these readings on a cut slope off the R403 near Celbridge, where the underlying limestone till meets the alluvial silts of the Liffey floodplain. Combined with piezometer data, this tells us exactly where the failure plane is developing before any crack appears on the surface. For sites near Castletown Estate or along the river, test pits let us log the transition between the weathered upper layer and the competent rock, while in-situ permeability tests quantify how fast water moves through the colluvium after a heavy Kildare rain.
A slope that drains is a slope that stands. Controlling groundwater is 80% of the stability equation in the glacial soils around Celbridge.
