DJ Scheffler.Inc. Foundation Drilling and Shoring
Environmental Drilling

D.J. Scheffler, Inc. provides drilling services to the environmental professional. Our large inventory of various types of drill rigs and equipment allows us to participate in a variety of environmental projects, including:
  • Secant Pile Cut-Off WallsA non-permeable subsurface wall created by a series of interlocking concrete filled drilled shafts. This process has many environmental applications including isolating a contaminated area below ground, controlling groundwater and minimizing any environmental impact caused by deep excavations where subsidence is anticipated.
  • Ground Freezing A process used by geotechnical engineers whereby the subsurface is frozen using specialized drilling techniques to achieve either a more stable subsurface and/or to create a frozen barrier to control groundwater infiltration.
  • Soil Sampling Refers to a wide variety of techniques generally used to analyze specific characteristics of subsurface materials.
  • Pieziometer InstallationA device installed in a drilled shaft that is used to accurately measure fluctuations in groundwater levels.
  • Pressure GroutingA process whereby grout is injected at various pressures via a drilled shaft into the subsurface. Reasons for grouting vary considerably and have numerous applications in the environmental engineering field.
  • Bentonite Slurry WallsSlurry walls are used to contain contaminated ground water, divert contaminated ground water from the drinking water intake, divert uncontaminated ground water flow and/or provide a barrier for the ground water treatment system.
  • Methane Well Installations – A well drilled typically at a landfill site intended to alleviate the buildup of methane gas.
D.J. Scheffler works closely with geologists, geotechnical engineers and governmental environmental agencies in environmentally sensitive areas and maintains a staff of qualified personnel with 40 hour HAZWOPER training, 8 hour HAZWOPER supervisor training and hazardous materials technician training. We have experience working in fuel refineries, blue-line stream channels, and other eco-sensitive environments. D.J. Scheffler will continue to explore new technologies and applications related to the environmental profession so we can continue to provide exceptional service to this growing industry.
