Introduction

FES provides both single wall and double wall casing. The dimensions of FES casing are designed to match most casing brands in the global foundation drilling market.
- Double wall casing is for temporary using, which is designed especially for transmitting high rotational and vertical forces created by the machine.
- Single wall casing is usually for permanent using, which is mostly used in the soft condition and the pile doesn’t have to be too deep.
