But here is the silver lining: cheap, affordable geotechnical drilling rigs are plentiful and price with performance. In this buyer's guide, you will learn important considerations in choosing the best geotechnical rigs for small contractors and cost-effective soil testing strategies.
[pdf] Drilled shafts are high-capacity deep foundation systems, also known as drilled piers, caissons, bored piles, or cast-in-drilled-hole piles (CIDH). Drilled shafts for structural support can be installed by the dry (open hole), stabilizing polymer slurry, or steel-cased methods.
[pdf] Surface drilling rigs are hydraulic drill rigs typically designed for small to medium-scale quarries and small-sized open pit mines, suitable for rock drilling applications where rock hardness exceeds F10 in aggregate quarrying, civil engineering, road construction, open pit mining, hydropower plant construction and other blasthole drilling projects.
