5. Business Segments Overview
The Construction Materials Characterisation Laboratory consists of accredited
Laboratory where the technical characteristics (physical-mechanical, durability and
chemical properties) of construction materials are assessed; to guarantee their reliability
and safety and compliance with national and international standards and regulations.
•
TTH establishes site laboratories as per client testing requirement fitted with the testing
equipments and technicians to carryout tests. The advantage of site laboratory is to
carryout tests rapidly, client saves the cost of manpower and avoids the building of
equipment inventory. Field lab setup of Soil Testing has been done for GMR at DFCC.
TTH undertakes fixed rate contracts for fulfilling third party testing requirements at very
reasonable pricing .We collect the samples from site and carryout tests in quickest
time frame. Monthly invoicing helps the client to maintain their cash flow.We also
extract core of concrete and bituminous material and test them at our laboratory.
