Non-Destructive Testing & Evaluation
Information is the lifeblood of a successful restoration strategy. Non-destructive testing and evaluation (NDT&E) provides critical advance intelligence about an asset’s underlying construction and condition, with minimal disturbance to its fabric. SUPERSTRUCTURES’ investigative arsenal includes an array of state-of-the-art equipment for in-situ testing, and the skill and experience to correctly interpret its output.
Infrared (IR) cameras (using surface temperature variations) and electrical impedance (EI) meters and scanners (using sub-surface variations in dielectric permittivity and conductivity) provide an indication of moisture trapped in roofs, walls, and floors. Ground penetrating radar (GPR) antennas, covermeters, and pachometers (using reflected and induced electromagnetic pulses) and sonic and ultrasonic detection tools (using reflected stress waves) indicate the presence or absence of metal (pipes, beams, rebar, cables, ties, and anchors), air, and water (PVC conduit, missing grout, delaminations, voids) in concrete and masonry. Membrane integrity mapping, mass magnetic probes (MMP), Schmidt rebound hammers, coating adhesion and anchor pull-out testers, borescopes, thickness gauges, and other devices are used to assess and track the health of roof systems and masonry, concrete, and steel.
