Cast-in-Situ (Bored) Pile Foundation

Cast-in-situ pile foundation involves boring a hole into the ground to the required depth and then filling it with reinforced concrete on-site. This method is widely used in Bangladesh for high-rise buildings, bridges, and industrial structures where high load-bearing capacity and adaptability to varying soil conditions are required.

Our Process
1.           Site survey and pile layout marking as per structural drawing
2.           Boring using rotary/percussion rig to the design depth, with casing and using bentonite slurry support to prevent collapse (when needed)
3.           Cleaning of the borehole base to remove loose sediment
4.           Lowering of reinforcement cage to the designed depth
5.           Concrete pouring using the tremie method to avoid segregation and ensure continuous, void-free concrete
6.           Curing and quality checks, including concrete cube testing
Equipment Used
•             Rotary bore piling rigs
•             Tremie pipes for underwater/slurry concreting
•             Reinforcement cage fabrication tools
•             Concrete batching and pumping equipment
Standards Followed
•             Bangladesh National Building Code (BNBC)
•             ASTM D1143 (for related load testing)
•             Site-specific structural design specifications provided by consulting engineers
Typical Applications
•             High-rise residential and commercial buildings
•             Industrial factories and warehouses
•             Bridges and flyovers
•             Sites with variable or soft soil conditions where driven piles are unsuitable
