Concrete Imaging Services (CIS), A DeAndrea Company

The most advanced system to locate rebar, conduit, post tension cable, voids, PVC pipes, water and heating lines within the concrete as well as check the thickness of the concrete.

Concrete Imaging Services (CIS), A DeAndrea Company was founded in 2002 and is a contractual firm that specializes in ground penetrating radar (GPR).

The service we provide is nondestructive testing by using GPR equipment to locate rebar, conduit, post-tension cable, voids, PVC pipes, water and heating lines within the concrete, as well as check the thickness of the concrete. CIS is also known for its expertise in core drilling as we are able to core drill holes as needed directly after locating targets all within 1 mobilization. As one of the first of its kind, the demand for our services has never been greater; and we are a rapidly expanding enterprise.

This new state of the art equipment enables us to view concrete slabs and walls up to 18” thick from one side or 36” thick with access to both sides to locate targets.

The GPR system has three components which consist of the Control Unit, the Antenna and the Power Supply. The control unit contains the electronics that produce and regulate the pulse of radar energy that the antenna sends into the concrete creating ultra sound like waves. The antenna receives the electrical pulse and amplifies it then transmits it into the concrete.

GPR works by transmitting a small pulse of energy into the material, recording the strength and the time required for the return of any reflected signal. A series of pulses over a single area produce what is called a scan.

Metals are considered to be a reflector which does not allow any signal to pass through; therefore...
