The SONICaliper™ provides a full 360° profile through dynamic testing. It determines the diameter, assesses the verticality, and calculates the volume of deep foundation excavations.
Typically, the SONICaliper™ takes a profile every 3 m inside a steel casing and every 1.2 m in an open excavation to ensure the foundation is cylindrical.
Immediately after the excavation has been measured, the SONICaliper™ uses our in-house software to transform its highly accurate readings into calculations and ‘as constructed’ images of the excavation profile, including a three-dimensional model – a welcome opportunity to ‘see’ the foundations true shape.
Having reviewed and assessed all the available information, the engineer, designer and contractor can all feel confident that the foundation shaft or wall has been manufactured to the correct specification and meets the required quality standards.
Additional profiles can be taken if any anomalies or non-specification conditions are identified in shaft volume, diameter or verticality. The anomalies can then be evaluated in terms of their impact on shaft quality before and long-term integrity and the reinforcement cage is inserted, and the concrete is poured.
