In-situ testing is a crucial component of geotechnical site investigations, providing real-time data on soil and rock properties directly at the project site. At Aitken, we offer a comprehensive range of in-situ testing services across Scotland and the Northeast of England, delivering accurate and immediate insights to inform your construction and engineering projects. In-situ testing involves conducting tests directly within the ground to measure the physical and mechanical properties of soils and rocks without the need for sample extraction. This approach offers a realistic assessment of site conditions, crucial for reliable geotechnical analysis and design.
We provide a variety of in-situ testing methods to suit different project requirements:
The California Bearing Ratio (CBR) test is a vital in-situ testing method used to evaluate the strength and bearing capacity of soils for road construction and pavement design. It involves measuring the resistance of soil to penetration by a standard plunger. This test is performed directly at the project site, providing a realistic assessment of the soil’s bearing capacity and its suitability for supporting road and pavement structures.
Sand replacement testing is a crucial method for determining the in-situ density of soil, essential for assessing soil compaction and suitability for construction projects. Sand replacement testing involves removing a soil sample from a test site and filling the void with a known quantity of sand. By measuring the volume of sand used to fill the void, the density of the in-situ soil can be accurately calculated. This method is widely used to evaluate soil compaction and ensure that it meets the required specifications for construction.
Plate load testing is a vital field test used to determine the bearing capacity and settlement characteristics of soils and pavements under load. Plate load testing involves applying a controlled load to a steel plate placed on the ground surface or a prepared subgrade. The test measures the soil’s response to the load, providing valuable information about its bearing capacity and settlement behaviour. This data is crucial for designing foundations, pavements, and other load-bearing structures.
Percolation and soakaway tests are essential methods used to evaluate the infiltration rate of soil, which is crucial for designing effective drainage systems, soakaways, and septic systems. Percolation testing involves digging a test pit and filling it with water to observe how quickly the water percolates into the soil. This test measures the soil’s infiltration rate, which is essential for designing drainage solutions. Soakaway tests are similar but focus specifically on the capacity of the soil to absorb stormwater runoff, ensuring that soakaways and drainage systems are properly designed to prevent flooding and waterlogging.
