Geosynthetics Testing Services for Engineering & Compliance
RSA Geolab is an AASHTO-accredited laboratory with documented quality procedures and third-party oversight. We provide standards-based geosynthetics testing services to support engineering decisions, quality assurance, and regulatory compliance for engineers, contractors, and manufacturers. Our laboratory delivers accurate, repeatable data to support design validation, quality assurance, and regulatory compliance.
With over 30 years of experience and accreditation from leading organizations, we support a wide range of geosynthetic materials and testing requirements. We also provide geotechnical laboratory testing for geosynthetics used in infrastructure, environmental, and containment applications.
Applications of Geosynthetics Testing
Geosynthetics testing supports a wide range of project types, including transportation infrastructure, environmental containment systems, stormwater management, landfill construction, and civil engineering development. Accurate laboratory data helps verify material performance, confirm specification compliance, and support long-term durability in demanding field conditions.
Why Geosynthetics Testing Matters
Reliable geosynthetics testing helps engineers, contractors, and manufacturers evaluate strength, durability, permeability, and interface behavior before materials are installed in the field. By validating performance in advance, project teams can reduce risk, improve quality control, and support regulatory and design requirements.

Our Commitment To Quality
Our laboratory operates under strict quality control procedures, with routine audits by both internal teams and external agencies.
All testing follows established standards from ASTM, AASHTO, the Geosynthetic Research Institute (GRI), and the U.S. Army Corps of Engineers to ensure consistent, accurate, and defensible results.
Over 30 Years Of Experience
RSA Geolab has extensive experience testing geosynthetic materials across a wide range of applications. We work with engineers, contractors, and manufacturers to deliver reliable, standards-based results that meet project specifications and industry requirements.
