What is Soil Testing Equipment? Why is it Important?

It is critical to examine the quality of the soil and research its behaviour under predicted loading patterns before beginning the construction of a structure, road, or embankment. The range of soil behaviour can be explained by the fact that soil has a direct relationship with location. 

The location’s load-bearing capacity provides an estimate of how much weight a cross-sectional unit area of soil can hold. Designers can then determine the depth to which foundation pieces should be excavated. Depending on the quantity of moisture available, soil with a larger percentage of clay will expand or shrink.

Soil Testing Types

Residual, physical, and chemical examinations are the most common types of soil testing. Shear strength, elasticity, and porosity are some of the most common physical tests done. Grain size analysis, density, moisture levels, permeability, load-bearing capability, penetrating strength, and other testing are available. 

It is typical to practice in material testing to describe the technique to be used for sample preparations in standards, as the test findings will be influenced by how the samples were produced. As a result, sample preparation devices are required in every laboratory. HEICO produces the whole spectrum of testing equipment, including the soil testing instruments that are necessary for each of the functions.

Test for Shear Strength

The shear strength test is the most widely used method for determining load-bearing capacity. This test is done in a triaxial cell, which is a particular transparent container. Special instruments are used to prepare the sample, and the sample’s dimensions (usually cylindrical) are determined by the ultimate usage or the kind and specific design of the structure or road.

  • Grain size, moisture content, and strength at various moisture levels are determined using geotechnical testing equipment. Other tests are performed to determine the permeability of water or fluids in soils or to offer compaction controls for engineered fills.
  • To evaluate the ideal moisture and density of soil, a soil testing machine is employed. Samples are formed using compaction equipment and moulds to determine the compacted density and unit weights of soils. Controlling the placement and compaction of soil embankments and engineered infill is based on test findings.
  • CBR (California Bearing Ratio) equipment is available for use in the laboratory or in the field. The moisture content and strength of laboratory samples are determined using CBR lab testing. Field tests are used to determine the strength of existing soils. 

A three-dimensional test

The Triaxial test includes not only the test cell that holds the sample but also a loading system and soil testing lab equipment that has the provisions and features to carry out the loading stages, procedure, and pattern. The measurement, control, display, and analytical systems necessary to provide the data are all included in the loading system. 

Advanced hydraulics, including a hydraulic power pack that is well regulated by hydraulic valves operated by complicated computer algorithms, is used to meet the exact demands of this test. HEICO employs proprietary software to ensure that the process is controlled in accordance with industry standards. HEICO has experience with both conventional and bespoke equipment, depending on the needs of the customer.


The wide range of construction activities necessitates onsite testing. As a result, an increasing number of businesses choose to establish testing labs with soil testing equipment for agriculture closer to their construction or road-building sites. Thanks to its network of people, HEICO can deliver locally and give local onsite servicing. Using computer-based communication systems, service is provided both onsite and off-site/remotely.
