During May 2018, SIS Ltd were commissioned by Tasiker Industrial, on behalf of Hertfordshire County Council, to undertake testing to the North abutment wall of Kingsmead Viaduct.

Concerns were raised of the possibility of voids with the abutment concrete.

In order to identify if voids were present, SIS Ltd undertook the following surveys:

• 24No. Ultrasonic Pulse Echo Velocity Scan Surveys
• 4No. GPR Scan Surveys
• full Delamination Tap Hammer Survey

Following undertaking the specialist concrete surveys and interpreting the data obtained, it was confirmed that several areas to the abutment where highlighted as possibly having voids present. A full comprehensive report was compiled following the works detailing all scan images obtained.

The works were completed efficiently and to the clients brief and satisfaction with the full report submitted within 7 working days of the survey being undertaken.

Please get in contact for any civil or structural pre-, during, or post-work surveys, inspections, investigations, and testing requirements.
