Double Wall Casing

Double Wall Casing

Category:

Description

The Segmental Casing System is designed to provide borehole support and ground stabilization during bored piling and deep foundation construction. Available in both single-wall and double-wall configurations, the casing system helps maintain borehole integrity, prevent collapse, and improve drilling accuracy in challenging ground conditions.
Manufactured from high-strength structural steel with heavy-duty casing joints and wear-resistant cutting shoes, the system is suitable for temporary and permanent casing applications. Modular casing sections allow easy transportation, assembly, and customization for various pile diameters and project requirements.
