Soil Testing

In the field of civil engineering, nearly all projects are built onto, or into, the ground. Unlike other materials, which are subjected to strict controls during manufacture or processing, soil is usually used in the natural condition. Whether the project is a structure, a roadway, a tunnel, or a bridge, the properties of the soil at that location are of great importance to the civil engineer

Soil Testing In Depth

Here at ACS Testing we have the facility and expertise to determine a range of physical properties to classify the soil and determine its engineering properties, both in-situ and in the laboratory.

 

In-Situ Soil Testing

We provide technicians to carry out on-site sampling and testing of soils.

 

  • Sampling of soils
  • In-situ density - sand replacement method large pouring cylinder
  • In-situ density - core cutter method
  • In-situ bulk density - nuclear method - comparative tests
  • In-situ bulk density - nuclear method - absolute tests
  • In-situ bulk density - nuclear method - compliance tests
  • In-situ moisture density - nuclear method - comparative tests
  • In-situ California Bearing Ratio (CBR)
  • In-situ plate bearing tests
  • Moisture condition value (MCV)
  • TRL Dynamic Cone Penetrometer (DCP)

 

Laboratory Testing

Our permanent laboratories provide a comprehensive range of tests on soils.

 

  • Moisture content - oven drying method
  • Liquid limit - cone penetrometer
  • Plastic limit
  • Plasticity index & liquidity index
  • Particle density - small pyknometer & gas jar
  • Particle size distribution - wet sieving & dry sieving
  • Uniformity coefficient
  • Particle size distribution - sedimentation by hydrometer method
  • Dry density / moisture content relationship - 2.5kg & 4.5kg rammer & vibrating hammer
  • Moisture condition value (MCV)
  • Moisture condition value / moisture content relationship
  • California Bearing Ratio (CBR)
  • Undrained shear strength in triaxial compression without measurement of pore pressure
  • Undrained shear strength of remoulded cohesive material
  • Oedometer
  • Constant head permeability
  • Large shear box
  • Hand shear vane
