In this video, we explore the concept, construction procedure, and applications of under-reamed piles used in foundation engineering. Under-reamed piles are specially designed bored cast-in-situ concrete piles with enlarged bulb-shaped bases, widely used in expansive and weak soils to improve load-carrying capacity and reduce settlement.
We cover key topics such as:
• Introduction to Under-Reamed Piles – purpose and importance
• Components of Under-Reamed Piles – shaft, bulb, reinforcement, and spacing
• Construction Procedure – boring, under-reaming, reinforcement placement, and concreting
• Applications – foundations in black cotton soil, low-rise buildings, towers, and industrial structures
• Advantages – increased bearing capacity, resistance to uplift, and economical construction
Through clear visuals and explanations, this video is ideal for civil engineering students, site engineers, and construction professionals. Whether you're preparing for exams, presentations, interviews, or practical site work, this video provides a strong understanding of under-reamed pile foundations and their field applications.
