Twenty years of development and investment have equipped the Invariants Ltd Test Laboratory with all the facilities and equipment it needs to test and validate a broad range of geotechnical engineering, in full compliance with normative standards or to client’s own requirements. Reliablity of test depands on the modes like: sample collection, preservation, laboratory testing, presentation of data etc. We ensure accurate processing of samples at every stage of these modes for pin point accuracy in testing, and reporting with commitment, quality and safety. Keeping this in mind the company maintains a laboratory of its own at its office annex at Dhaka. Field works are performed by experienced geotechnical personnel with the help of world class precision equipment. The test lab is run by engineers having extensive experience gained both from home and abroad in the relevant discipline.
