Geotechnical Engineering in Dover, DE

Dover area sites trade well-drained Columbia sands against plastic Potomac clays within short distances. Bearing, settlement, and swell questions on Dover sites get answered by data, instead of assumptions borrowed from another Delaware job. Consolidation and strength testing on Dover samples quantify settlement, before DE designs inherit a surprise. We support Dover on a mobilization basis from Texas, and Delaware requirements are settled before mobilization, not after.

  • Soil borings and sampling programs sized to the structure and site
  • Laboratory index testing: Atterberg limits (ASTM D4318), moisture content (ASTM D2216)
  • Moisture-density relationships and bearing evaluation for foundations and pavements
  • Expansive-soil characterization for slab and pavement design
  • Construction-phase verification: proof rolls, subgrade acceptance, fill placement observation

FAQ · Dover

Do I need a geotechnical report before building?

Most commercial permits, lenders, and structural engineers require a geotechnical report to establish allowable bearing pressure and foundation type. It is the least expensive insurance a foundation can have.

How long does a geotechnical investigation take?

A typical light-commercial site runs one to two weeks from drilling to final report, depending on lab test turnaround and access conditions.
