SANA ENGINEERS laboratories constitute a major part of its wide-ranging services. In-house facilities provide a complete set of material testing services, for determination of engineering properties of soils, rocks, and any construction materials and chemical properties of water.
The laboratory technicians are all trained to operate in the computerized data analysis and result interpretation software system applications that enable them to provide reliable and fast services.
