Soil Investigation

Soil Investigation is the process of establishing the type of soil strata at a specific area, by drilling holes into the earth to obtain samples. The samples obtained are then studied and verified by a team of experienced engineers. Soil investigation helps to provide information on soil parameters upon which design of subterranean structures such as piles and retaining walls can be carried out.

Geotechnical Instrumentation

Construction activities in particular deep excavation, tunneling and pile driving in close proximity to existing structures can cause damage and endanger lives. Hence, it is imperative to conduct continuous monitoring and assessment of the impact of the construction activities on the surroundings.

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.

Field Services

Field Services is paramount to determining the stability of a structure. Various testing methods such as the static pile load test, plate load test and the Pile Driving Analyzer (PDA) test (Using the patented PDA test frame method) are available. These tests help to determine the stability of a structure, based on ground settlement.
