Soils Engineering Reporting

Arrow Engineering's Geotechnical Division maintains a full-service materials laboratory, specializing in soils, aggregates, concrete and asphalt testing. We participate in correlation/proficiency testing programs with ASHTO, and CCRL.


Our materials testing services test, analyze, and certify a wide range of materials for purity, chemical compatibility, and environmental impact. Our licensed inspectors help to make sure the correct procedures are in compliance with the applicable codes, plans, and specifications. Special inspection can help ensure that no shortcuts are taken during construction that may diminish the quality of a project. Inspections can be provided on a periodic or continuous basis, depending on project and client needs.


Laboratory soil testing capabilities meet requirements of soils-materials evaluation by current geotechnical standards and are illustrated by the following types of tests.





Dry density

Atterberg limits

Grain size analysis



Maximum dry density

Sand equivalent

Expansion index



Reinforced concrete

Structural masonry

Spray applied fireproofing

Structural steel and welding

Post tension concrete

Pile driving and caissons
