Cased auger pile
A cased auger pile is formed using the twin rotary-drive system (also called ‘FoW’ or Front of Wall system), with extraction of soil under a temporary casing. The system is particularly suitable for the manufacturing of a pile wall (secant pile wall, tangent pile wall, contiguous independent piles). The execution is vibration-free and with limited noise pollution. The reinforcement is placed after the concreting phase.
Construction sequence
Fields of application
• Particularly used for the realization of soil retaining and/or water retaining walls (see secant pile wall)
• Can be executed throughout existing, old foundations (masonry)
• Can be installed close to existing facades (e.g. a few centimetres)
Environmental impact
• In vibration sensitive areas: the pile is formed without vibration or shocks
• In a noise-sensitive environment: low noise level generated
• Removal of soil
• A stable, dry and flat work platform is required.
