There are various types of soil which differ in physical & chemical compositions, like sand, silt, clay, loam, peat etc. Although the primary use of soil in our nature is to support plants or vegetation, but for all construction related activities like buildings, dams, tunnels, etc. soil is an indispensable ingredient and knowledge of its properties determine its suitability for a particular purpose. The various tests on soil can be broadly categorized into two types :

Classification Tests , which provide information about the general soil characteristics as well as the mechanical properties like strength, size-grading, permeability etc. These tests help to classify soil samples into various different types.

Tests To Determine Engineering Properties , which evaluate the usefulness or suitability of a particular soil specimen for a construction related work.

National Testing Lab has a vast & rich experience when it comes to conducting various tests on soil and also carrying out soil investigation studies.

Soil Special Tests :

  • CBR, laboratory, soaked single point
  • CBR, laboratory, soaked three point
  • Chloride content
  • Density, in-situ, by sand cone
  • Core Cutter Method of Density Measurement
  • Electrical Resistivity
  • Linear shrinkage Test/Characteristics of Soil
  • Classification of Soil
  • Grain-size Distribution Curve/Grading Curve
  • Consistency of Soil
  • Atterberg Limits
  • Soil Compaction, Consolidation & Settlement
