Malcolm Drilling utilizes modern hydraulic top drive rotary drilling rigs as the backbone of their entire equipment fleet. The operating weight of these rigs ranges from 45-tons to over 300-tons. The versatility of these machines allows Malcolm Drilling to utilize them for various kinds of work, including jet grouting, deep soil mixing (DSM), Auger Cast (CFA), or Omega pile (displacement pile) installation, as well as large diameter cased or uncased shafts.
