BTRA is recognized (based on earlier experience, expertise and facility) as a Centre of Excellence for Geotech by the Ministry of Textiles, Government of India.
BTRA setup a new Geotech Laboratory with all testing facilities to test Geotextiles, Geomembranes, Geocomposites, Gabions, Geosynthetic Clay Liner, Geogrids, Prefabricated Vertical Drain etc. Also, BTRA is strengthening its information resources on Geotech by procuring various books and international test methods such as ASTM, INDA, EDANA, ISO, etc.
This laboratory is accredited as per the following:
- GAI-LAP Accreditation of Geosynthetics Institute, USA
Geotech Laboratory is now accredited by Geosynthetics Institute (GSI), Folsom, Pensylvania, USA under the GAI – LAP Accreditation Programme for the following 24 tests of geosynthetics products.
It is pertinent to mention that BTRA is the first institute in India and probably only the third institute outside USA to get this coveted accreditation. What this means to the geosynthetics producers and users is that they can get the products tested in BTRA with utmost confidence that the accuracy of the results are as good as any other GAI-LAP accredited laboratories. They can get the tests done in India, thus saving time and money without compromising on the quality of the results.
