The AGEwall is a novel technique for embedded retaining wall construction. The concept arose from the desire to reduce the required wall penetration for a wide, shallow basement on a site where very soft ground extended a long way below the proposed foundation depth.

As illustrated in the accompanying diagrams, the AGEwall provides pre-placed props to the perimeter wall at depth before internal excavation is commenced. The wall is installed in panels, each having a prop connected to the wall by means of a hinge. The panel is placed in a trench, with the prop initially held vertically close to the panel. Subsequently, a slot is excavated perpendicular to the wall to allow the prop to be rotated about its lower hinge and connected to a restraint system. In this way lateral support is provided to the wall at depth before bulk excavation takes place.

As an alternative, in suitable ground, the wall panel could be driven or jacked into place; a pre-bored hole at the prop position may be used to ease installation.
