Bored Piling Contractors – High-Capacity Cast-in-Situ Foundations

Technical Overview

Bored piling involves the excavation of a circular hole followed by the installation of reinforcement and concrete. This method is preferred for high-rise buildings requiring high end-bearing capacity.

Construction Methodologies

We employ established methodologies tailored to the project requirements and soil conditions:

System
Rotary drilling
System
Bentonite slurry support
System
Temporary or permanent casing

Engineering Considerations

Soil stability during drilling and concrete flowability are critical.

Risk Mitigation

Potential for borehole collapse in loose sand layers is mitigated by slurry management.
