ABSTRACT:
A method of mapping steel reinforcements in an existing concrete foundation. The method includes determining the depth of the concrete foundation. Further the method entails transmitting radar signals into at least one section of the concrete foundation and collecting reflection data in response to the radar signals being transmitted into the concrete foundation. Based on the collected reflection data, determining the general location of at least some of the steel reinforcements in the concrete foundation. Thereafter, surgically cutting into the concrete foundation and exposing at least some of the steel reinforcements in a portion of the concrete foundation. Once some of the steel reinforcements are exposed, the method entails measuring the size and spacing of the steel reinforcements. Based on the exposed steel reinforcements and the measurements taken, mapping the steel reinforcements throughout at least a portion of the concrete foundation by illustrating, for example, the size of steel reinforcements, the spacing between the steel reinforcements, and the location of the steel reinforcement relative to one or more selected dimensions of the concrete foundation.
