Laboratory Testing

EEI maintains an in-house, well-equipped laboratory facility geared toward analyzing the physical properties of soil materials for engineering purposes.

Accreditation

Earth Engineering Inc.'s laboratory in East Norriton is AAP (AASHTO Accreditation Program) accredited. This means that our personnel, procedures, equipment, facilities, and quality management system (QMS) have satisfied the AASHTO R-18 requirements and the on-site assessment provided by AMRL (AASHTO Materials Reference Laboratory) for the following tests:

ASTM D 698, Standard Proctor
ASTM D 1557, Modified Proctor
ASTM D 1883, CBR
ASTM D 2216, Moisture content
ASTM D 2487, Classification
ASTM D 4318, Liquid & plastic limits, index of plasticity

All data analysis and report generation is performed in-house by our Laboratory Director and Professional Engineering staff.
