Laboratory

To meet our quality policy with the expectations and needs of our clients we have experience and professional laboratory staff (engineers and technicians) and tested equipment’s which calibrated on a regular basis by following the national and international standards, with high quality controlled procedure in accordance to international classification. Aggregate materials and fresh concrete were tested and checked daily, weekly and monthly as sieve analysis, specific gravity, elongation, flakiness, concrete work-ability, concrete strength, trial mixes, etc. according to the international specifications (BS/BSEN and/or ASTM) or any projects specification.
