Case Study - National Physical Laboratory
Hitting rebar can not only cause time and money problems for a project but can also cause structural issues. SUMO recently carried out a survey at the National Physical Laboratory to help them locate rebar.
- SUMO Geophysics was asked to determine the location of rebar at the National Physical Laboratory in Teddington.
- The client believed the rebar spacing to be 200mm but needed clarification and its precise location.
- A Ground Penetrating Radar Survey (GPR) was conducted on-site.
- The Survey used a GSSI High Frequency Radar antennae to locate the rebar.
- The survey determined that the site was reinforced and the bars were located between the depths of 0.07m and 0.25m, with spacing between 0.20 and 0.60m.
- The information provided by the survey allowed the client to work in-between the rebar to install industrial machinery and fix it to the concrete slab.
- With a fast turnover SUMO were able to locate the rebar and report back to to the client promptly. The client was able to install the machinery within 3 days of our initial site visit.
