Earth Retention

Consistently provide ground reinforcement and strengthening

DBM is a recognized industry leader in developing and implementing soil nail and ground anchor technology.Soil nailing is a cost effective method of providing earth retention structures for support of deep excavations, slopes, bridge abutments and roadways. Soil nails are primarily used to reinforce and strengthen the existing ground by installing closely spaced steel bars secured by grouting. This technique creates a composite reinforced soil mass stable enough to retain the ground on a temporary or permanent basis.

Ground anchors differ from soil nails in that they are posttensioned structural elements, installed and pressure grouted in soil and rock to transmit an applied tensile load into the ground. Typical applications include anchored earth retention to stabilize excavations and slopes, resisting vertical uplift forces generated by hydrostatic, seismic and overturning forces. Commonly used in both temporary and permanent applications, ground anchors can provide significant cost savings over more conventional mass concrete structure alternatives.

DBM’s vast experience in design/build soil nailed and anchored earth structures has resulted in the successful construction of hundreds of specialty geotechnical projects including:

  • Earth Retention
  • Excavation Support
  • Slope Stabilization
  • Dam Anchorage
  • Bridge/Equipment/Building Tiedowns
