  • Auger drilling from 4” to 15”
  • Soil sampling- split spoon, continuous dry coring
  • Water sampling - grab water and hydropunch
  • Well installation – monitoring and extraction
  • Well abandonment – over drilling and pressure grouting
  • Angle drilling
  • Nested, cluster and multi-point wells
  • Remediation- injection, extraction, sparge & vapor points
  • Conductor casings
  • Monitor wells and vapor points
  • Remediation – injection
  • Rigs include Truck-mounted, limited access, all-terrain and Portable
