What is GAI-LAP?
GAI - Geosynthetic Accreditation Institute
LAP - Laboratory Accreditation Program
The Geosynthetic Accreditation Institute-Laboratory Accreditation Program (GAI-LAP) is a test-by-test accreditation program based on site audits and annual proficiency tests.
The program is intended to insure that the specific laboratory is capable of properly rendering the tests that they contract to perform.
The essence of the program is to accredit geosynthetic testing laboratories for performing consensus standardized test methods insofar as equipment, documentation and testing protocol is concerned.

Today, some 12,000 ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.
