Cracking was identified within the ground floor concrete slab of a large operational warehouse, prompting the need for investigations to determine the depth, extent and significance of the defects. McFarland Consulting Ltd were appointed to assess the slab condition and confirm its suitability for continued use.
MCL undertook a combination of intrusive and non-destructive investigations, including small-diameter core drilling to establish crack depth and orientation, ultrasonic pulse velocity testing to estimate crack propagation, and extraction of a concrete core for compressive strength testing.
Three-dimensional laser scanning was undertaken across the slab to produce detailed crack maps and a surface deviation heatmap. Due to the scale of the warehouse and the number of scan locations required, the works were delivered under significant time constraints and required extensive post-processing of large data sets.
Remote crack monitoring was installed to enable ongoing assessment of crack behaviour over time. The investigations provided clarity on the nature and performance of the slab, enabling the Client to manage the issue pragmatically while maintaining confidence in the continued operation of the facility.
