Field Compaction & Strength Testing (with SAC-SINGLAS accreditation)
Nuclear Density Gauge Test
(In accordance with BS 1377: Part 9: 1990, Clause 3)
The Nuclear Density Gauge (NDG) Test is a quick and reliable method for measuring the in-situ density and moisture content of soils in compacted layers. It plays a vital role in verifying compaction quality for earthworks, roads, and foundations. With immediate results for bulk density, moisture content, and dry density, this test provides fast and effective on-site quality control and assurance.
Sand Replacement Test
(In accordance with BS 1377: Part 9: 1990, Clause 2.1)
This method determines the dry density of fine and medium-grained soils by excavating a small hole and measuring its volume with calibrated sand. Ideal for sites where the nuclear density gauge method is not suitable, offering reliable, non-radioactive compaction verification.
In-Situ California Bearing Ratio Test
(In accordance with BS 1377: Part 9: 1990, Clause 4.3)
The In-situ California Bearing Ratio test (in-situ CBR) measures the in-situ load-bearing capacity of subgrade soils by pushing a plunger into the ground. Essential for road pavement design, assessing soil strength to support traffic loadings.
