Notts Ilkeston Road Concrete testing

Project Overview

During June 2016, RSI were commissioned by Aone+ to undertake a technical survey to selected elements of Notts Ilkeston Road Underbridge which comprised of the following:

  • Delamination survey of test areas using lump hammer
  • Half cell test grids at 500mm spacing’s to abutment panel walls & cill beams
  • Dust drilling to obtain samples for subsequent chloride ion contamination
  • Main reinforcement cover survey
  • Concrete resistivity measurement undertaken using a 4 probe Wenner test
  • In‐situ test for depth of carbonation on freshly broken concrete surface
  • Dimension survey

All obtained dust and paint samples were retained, sealed and uniquely labelled in polythene bags, then returned to our UKAS accredited laboratory for chemical analysis. Once all the information was collated, a full comprehensive report was produced compiling of Auto CAD drawings with developed views of tested elements, half cell contour maps to assist in a rapid assessment of the tested areas, clear photographic evidence of tests completed and a UKAS accredited laboratory report for sampling results.

RSI staff utilised in‐house equipment to complete the works and comprised of the following :‐

  • Nissan Cabstar ‐ Multitel 22M Mobile elevated Working Platform
  • Hilti PS250 Cover meter (Ferroscan)
  • Hilti TE‐60 hammer drill with 20MM drill bit
  • Elcometer half cell potential monitor and electrode
  • Resistivity 4 probe Wenner kit
  • All required PPE

The works were completed within the scheduled programme and to the clients brief. All testing was carried out following our in‐house testing procedures and in accordance with BA35/90.
