Non Destructive Testing Services

Non-destructive testing (NDT) refers to the testing/verification of materials, in order to check, inspect or evaluate the surface for the presence of any internal flaws, defects, and discontinuties,without damaging it or impairing its future usability. Basically, NDT testing is used to investigate the material integrity of the test item.

Metals & Alloys Testing

Curve Serveys & Lab Ltd is fully equipped to perform qualitative and quantitative analysis of almost all the known elements in the periodic table, be it metals, non-metals or alloys. The laboratory prossesses modern and sophisticated instrumens like ICP-OES, Spark OES and XRF besides AAS. all these techniques except AAS,offer the advantage of multi-element analysys with very high Sensitivity/low detection limit for all the elements.

Soil Investigation

Soil is a complex and non-homogeneous natural substance formed over periode of time due to various geological events and other natural processes. Its complexity is demostrate by its approximate composition which includes minerals (45 %), air(25 %), water(25 %), & organic matter (5 %). There are various types of soil which differ in physical & chemical composition, like sand, salt, clay, loan, peat etc.

Building Materials

Sine different construction items have different items have different properties and also their application are varied, a number of national and international specification pertaining to the scope of application and any have been formulated. The analyses of building materials have to be conducted as per various accepted standardized test methods. The various standards include IS,ASTM,BSI,ISO etc.

Level Survey

Surveyor's level, instrument used in surveying to measure the height of distant points in relation to a bench mark (a point for which the height above sea level is accurately known. The theodolite, or transit, is used to measure horizontal and vertical angles; it may be used also for leveling.

The primary reference at water-level recording stations is a set of stable bench-marks, installed in locations where their level should not change. Upon initial set-up of a station, the levels of the relevant parts of the installation are established and recorded by means of accurate leveling.
