Geotechnical Rock Analysis

Tests are performed on rock samples to determine their properties and characteristics. Understanding these properties is essential for the design and construction of civil engineering projects, such as foundations, roads, and bridges.


Igne's laboratory rock analysis testing services provide comprehensive and accurate data to help you make informed decisions about your construction and engineering projects. Our team of experienced geotechnical engineers and technicians uses the latest equipment and methods to test a wide range of rock properties, including:

  • Point load index
  • Porosity and density
  • Slake durability
  • Unconfined compressive strength


Our aggregate and rock testing services are used by a wide range of clients, including:

  • Civil engineers
  • Ground investigation and drilling companies
  • Geotechnical engineers
  • Construction companies and house builders
  • Mining companies
  • Government agencies


Point load index: A test that aims at characterizing rock materials in terms of strength. It is an index test, meaning that it can be performed relatively quickly and without the necessity of sophisticated equipment to provide important data on the mechanical properties of rocks.


Rock porosity is the percentage of voids in a rock. It is important to consider the rock porosity when selecting construction materials for applications. Rock with high porosity may be less durable than rock with low porosity. Rock with high porosity may also be more susceptible to weathering and degradation.


Slake durability is a test that measures the resistance of a rock to slaking, which is the disintegration of the rock when it is exposed to water. It is important to test the slake durability of rocks that will be used in construction applications, such as road subgrades and embankments. Rocks with low slake durability may disintegrate when exposed to water, leading to failure of the structure.


Unconfined compressive strength (UCS) is a geomechanical rock parameter that describes the maximum axial load that the sample can withstand without lateral loading. UCS is a parameter widely used in geotechnical design. On a large scale, the rock mass properties are highly affected by other factors including discontinuities, faults, and weathering.
