Not sure if your soil layers are compacted enough to hold structural loads? The FDD test using sand replacement method is one of the most trusted techniques for determining the dry density of soil, especially on coarse-grained or gravelly surfaces. This method is ideal when the core cutter is not suitable. At Becquerel Industries Pvt Ltd, located in Nagpur, our field experts carry out the sand replacement test as per IS 2720 to validate field compaction levels for safe and long-term support.
It’s especially crucial during highway projects, airport runways, rail beds, and industrial yards, where improper compaction can lead to surface settlement and failure. The test measures the weight of sand needed to fill a calibrated hole in the compacted layer, allowing accurate calculation of in-place density.
For engineers who want assurance before proceeding with concrete work or asphalt laying, this test offers a practical, field-ready solution.
Visit our Nagpur office or call us to schedule an FDD test and make sure your site compaction is solid, certified, and construction-ready.
