In geotechnical and environmental engineering, obtaining accurate soil samples is essential for reliable laboratory testing. One of the most effective methods is box sampling, which allows engineers to collect undisturbed soil samples while maintaining their natural structure. However, the accuracy of soil testing depends not only on the sampling method but also on how well […]
Construction in earthquake-prone regions requires more than strong materials and advanced designs—it demands the expertise of a geotechnical consultant in earthquake-prone areas. These specialists play a critical role in assessing ground conditions, mitigating seismic risks, and ensuring that infrastructure projects remain safe and reliable. Without proper geotechnical guidance, projects in seismic zones risk structural failures,
Hydrology and groundwater monitoring play a vital role in the success of mining, construction, and environmental projects. Without proper assessment of water movement and subsurface conditions, projects face risks such as flooding, contamination, or unstable ground. This is where geotechnical consultants become indispensable. Why Hydrology Matters in Projects Hydrology is the study of water movement,
The 2018 Palu Earthquake stands as one of Indonesia’s most devastating natural disasters. On September 28, 2018, a magnitude 7.5 earthquake struck Central Sulawesi. Soon after, a massive tsunami and soil liquefaction followed, destroying large parts of Palu, Donggala, and nearby regions. Causes of the Palu Earthquake The disaster occurred due to movement along the
Geotechnical engineering plays a crucial role in coal mining projects across Indonesia and worldwide. From ensuring slope stability to managing groundwater and designing safe foundations, geotechnical expertise helps reduce risks and optimize mining operations. This article explores the major challenges faced by geotechnical engineers in coal mining and the solutions that make operations safer, more
Soil investigation plays a vital role in geotechnical engineering, construction, and mining projects. One of the most important decisions in this process is selecting the right drilling method — Wet Drilling vs Dry Drilling. Each method has unique advantages and limitations depending on project requirements, soil conditions, and environmental factors. According to the International Society
A waterwell is an engineered structure designed to access groundwater from an aquifer through drilling or excavation. People use the extracted water for many purposes, including household needs, agriculture, industry, and commercial activities. Depending on the aquifer depth and water demand, waterwells can be categorized as shallow wells or deep wells. Functions of a Waterwell
In construction, mining, and geotechnical engineering, drilling plays a vital role in exploring underground conditions and obtaining soil or rock samples. The process helps engineers determine material properties, identify potential risks, and design safe and efficient structures. Based on the medium and technique used, drilling is generally divided into two main types: wet drilling and
Drilling is one of the main methods in soil investigation to determine subsurface conditions. Through this process, engineers collect essential data such as soil types, layer strength, and samples of soil or rock for laboratory testing. In practice, two drilling techniques are commonly applied: wet drilling and dry drilling. Understanding the differences between these two
Geotechnical drilling is a crucial part of soil and rock investigation for construction projects such as buildings, bridges, dams, and roads. One of the most important components in this process is the drill bit, which serves as the cutting tool that penetrates soil and rock layers. Choosing the right type of geotechnical drilling bit is
