Sample & Field Testing
Field Testing
Civilab offers a variety of field-testing services to suit the project’s needs.
We offer comprehensive field-testing services through dedicated teams equipped to perform on-site assessments and sampling. Our capabilities encompass a range of tests, including but not limited to:
• Field Density Testing: Utilising methods such as sand replacement and nuclear gauge (Troxler) to determine soil compaction levels.
• Dynamic Cone Penetrometer (DCP) Testing: This is essential for evaluating subgrade conditions, as it assesses the strength and compaction of in-situ soils.
• Test Pit Profiling: Excavating and examining soil layers to understand subsurface conditions.
Civilab conducts extensive soil and geotechnical investigations, ranging from small-scale assessments to large, complex projects.
Our services include soil sampling, profiling, laboratory testing, and detailed reporting, all tailored to meet specific project requirements. We also offer the establishment of site laboratories to facilitate ongoing testing and quality control throughout the construction process.
By adhering to national and international standards, Civilab ensures that our testing methods and results are reliable and trusted, supporting the successful execution of infrastructure projects across South Africa.
