Graphic element Subsurface radar as a tool for non-destructive testing in the construction industry
A new radar system allows information to be had about the nature and condition of constructions. Dielectric properties of a variety of materials, configurations and qualities were studied.

The objective of this project was to develop a new subsurface radar system for the non-destructive testing (NDT) of buildings and other constructions, enabling information to be gathered about their nature and condition. The new equipment transmits pulses of electro-magnetic energy, generally in microwave frequencies, and receives reflections from interfaces where there is a discreet change in material properties.

Partners also investigated the dielectric properties of brick, stonework, concretes and aggregates, as well as more complex materials, configurations and qualities, including multi-layer reinforcement, moisture, porosity and salinity. Current dielectric models were also improved by studying the responses of a number of radar systems to construction and material features incorporated into physical models, both in the laboratory and in the field.

The potential economic benefits include the direct sale of radar testing services and equipment, as well as improvements in European standards conformity and damage prevention.
