Assessment of foundation slabs with US-echo in the re-use process
- During the re-use process of existing concrete memebers like foundations information about geometry and location of piles or strip foundation is necessary. Ultrasonic echo with a need of only one-sided access may provide this information and help the engineer to assess foundations. Cost effectiveness by the re-use of foundations gains an increasing economic role due to decreasing average economic lifetime of buildings on urban sites. Results of systematic ultrasonic echo investigations at a slab from 75 cm to 125 cm thickness with ten different reinforcement ratios are presented. The influence of the varying reinforcement ratio and thickness on the reliability of the results is shown. Available data-processing algorithms based on reconstruction calculation and imaging of results to reveal the geometry of a slab and the location of piles or strip foundations are introduced. Practical guidance for the application of ultrasonic echo and its limits are presented to ensure reliable results.During the re-use process of existing concrete memebers like foundations information about geometry and location of piles or strip foundation is necessary.
