ALTECH COMPANIES

ALTECH Drilling & Investigative Services Ltd. (ALTECH Ltd.) is an affiliated firm that provides environmental and geotechnical sub-surface investigative capabilities throughout the Midwest / Eastern United States and Ontario Canada.  ALTECH Ltd. commenced operations in May of 2004 and is based in Waterloo, Ontario.

The subsurface investigative group currently operates the newest and most sophisticated Geoprobes (TM) available: the  6620DT track mounted probe unit and the Advance 6610DT track unit (two units available). The Advance 66 series of probes provide both probing services (i.e. Macro-Core Sampling and Dual Tube Sampling tools), plus 4.25-inch inside diameter hollow stem augering capabilities for 2-inch diameter monitoring well completion. This dual purpose system can be switched from direct push mode to augering mode in minutes.

The smaller track unit is especially useful for difficult terrain locations, or interior work within buildings.

The 6600 track units typically conduct the following investigation/remediation type works:

  • direct-push operations (continuous or discrete soil sampling, in-situ groundwater sampling, vapor probes/soil gas work, dual tube work, and small-diameter monitoring well installations/implants);
  • hollow stem augering (4.25-inch inside diameter) for monitoring well closure and conventional 2-inch monitoring well installations; and
  • sub-surface injection/placement of treatment fluids (ORC, KMnO4).

For tougher drilling conditions and deeper overburden and bedrock tasks, the Altech companies operate three  rotary drills. A CME75 truck mount unit, a CME550 all-terrain unit, and a Diedrich (D120) are available. A variety of hollow stem auger and solid stem auger systems are available. All units are provided with auto hammers for standard penetration test (SPT) sampling using spilt-spoon samplers.

Altech Drilling & Investigative Services Ltd. truly enhances the "full service" capabilities of the CRA Family of Companies to fulfill client needs.
