What Is Borehole Drilling for Soil Investigation? Borehole drilling for soil investigation is one of the most important steps before construction begins. The process helps engineers and geologists understand the ground beneath a project site. Accurate subsurface information reduces uncertainty. It also supports better engineering decisions from the very beginning. How Does the Process Work?…
Our team recently carried out Borehole Logging and Rotary Wash Boring Works in Kuala Lumpur for a landslide-related geotechnical investigation project. Using the reliable YWE D-90R Rotary Wash Boring Rig, the investigation was conducted to obtain critical subsurface information for slope stability assessment and ground condition evaluation. The scope of work includes: Borehole drilling and…
The Mackintosh Probe Test (MPT) is a commonly used in-situ soil investigation method in geotechnical engineering to quickly assess ground conditions. It is widely used in Malaysia and Southeast Asia for preliminary site investigations due to its speed, simplicity, and cost-effectiveness. The test is carried out by driving a steel probe rod into the ground using…
Essential Method for Subsurface Exploration Borehole drilling is one of the most important techniques used in geotechnical site investigation. It allows engineers to examine soil and rock layers beneath the ground surface and collect samples for detailed analysis. By drilling boreholes at selected locations, engineers can understand the soil profile, groundwater level, and engineering properties of…
Understanding Ground Conditions Before Construction Soil investigation is a critical step in any construction or infrastructure project. It involves examining the subsurface soil and rock conditions to ensure that structures are built on safe and stable ground. In Malaysia, soil conditions can vary significantly depending on location. From soft marine clay to residual soils, proper geotechnical…
At Terra Axis , we believe that a strong understanding of soil mechanics is fundamental to delivering reliable geotechnical solutions. Recently, our Principal Geologist, Muhd Akhyaar Kok conducted an internal knowledge-sharing session focusing on the essentials of Soil Investigation (SI) and the critical role of geotechnical laboratory testing in understanding ground behaviour. The discussion moved…
