Our Civil Engineering laboratories at Muscat, Sohar, Duqm and Buraimi cover wide range of mechanical, physical and chemical testing of soil, aggregate, concrete, rock, cement, asphalt, blocks, marble, tiles, water and other construction materials. The lab provides a laboratory testing support to our Geotechnical Engineering department. Our Civil Lab services may include: testing and investigation of building and road construction materials; laboratory and field characterization of soils and rocks; compliance of aggregate and cement with standards; design concrete mixes to specific requirements; testing of control samples for tensile and compressive strengths; testing existing material using cores and non-destructive tests; low and high strain dynamic pile testing, concrete durability tests such as chloride migration and rapid chloride permeability, etc.
