Soil or geotechnical investigation is used to determine the engineering properties of soil at a project site. Investigation determines the soil's capacity for bearing weight, holding foundations and other geotechnical concerns.

Our team are fully equipped to perform fill soil investigation and reporting for the advisability of your project site, noting any additional steps, hazards or points of contention.

More about Soil Investigation and Reporting.

The main goal of soil investigations is to determine the soil’s characteristics, such as composition, grain size, moisture content, and density. These factors influence the soil’s behaviour under various loads, essential for designing foundations and geotechnical structures. Soil samples are taken from different depths and locations, and lab tests provide accurate data.

Soil investigations also assess stability and bearing capacity, key for foundation design. In-situ tests like the Standard Penetration Test (SPT) and Cone Penetration Test (CPT) evaluate shear strength, compressibility, and other critical parameters to ensure the soil can support loads without excessive settlement.

Additionally, these investigations identify potential hazards such as soil liquefaction, expansive soils, and landslides, helping mitigate risks to ensure structural safety. The data guides foundation design and influences construction planning, such as excavation techniques and safety measures.

Stages of Soil Investigations.

1. Desktop Study and Site Reconnaissance: Initial review of geological data and site inspection to understand soil conditions and plan the investigation process.
2. Preliminary Soil Investigation: Basic testing, including drilling boreholes and visual soil classification, to gather general information about soil strata and groundwater conditions.
3. Detailed Soil Investigation: Advanced testing through in-situ methods like SPT, CPT, and laboratory tests to thoroughly evaluate soil properties for foundation design.
4. Supplementary Soil Investigation: Additional testing may be required if initial investigations reveal problematic soils, such as expansive or contaminated layers, to address specific issues.
