Earthing & Civil Drilling

Underdale Drillers will undertake a wide range of civil drilling services including investigative drilling for building projects, road construction, preparative work for bridge and overpass construction testing for slope and incline stability.

Our environmental capabilities include investigation by the installation of monitoring wells and instrumentation and probes, testing of soils at depth and analysis of groundwater reserves.

We employ equipment including continuous or hollow flight augers drilling, SPT (Standard penetration test), rotary air, mud or down hole hammer drilling, reverse circulation, diamond coring, conventional or wireline coring, undisturbed sampling and piezoelectric transducers installation.
