Balcony concrete restoration due to rebar corrosion may be the most expensive and inconvenient project a condominium will face. Therefore a proven, economical long-term solution is needed. CPT's System III impressed current cathodic protection system is the answer.
 
 

CPT's System III has been developed over the past 20 years to reverse the corrosion process. Utilizing our proprietary C2A conductive mastic anode, System III provides powerful and permanent corrosion protection. Our long life carbon conductive mastic tenaciously bonds to the concrete surface to deliver a prescribed amount of DC current directly through the concrete to reinforcing steel. C2A conforms to all concrete surface irregularities thereby increasing system flexibility and perfectly blending itself into the existing structure.
 

System III is controlled by a sophisticated yet simple network of controls. A heavy-duty rectifier converts AC to DC power, while utilizing approximately the amount of energy needed to run a 120-watt light bulb. The DC current is distributed through a main junction box to zones occupied by anode junction boxes. At each level the system is calibrated to deliver calculated amounts of current to each balcony zone. Platinum anode wires run off of header lines to deliver current to the conductive mastic. Internal feedback controls consisting of imbedded reference electrodes and a remote monitoring unit (RMU) allow the system to be monitored on site or from a remote station.

System III separates itself from the pack with recognizable key advantages. Innovative design and manufacturing techniques have enabled CPT to provide a high performance system at a relatively low cost. Due to the ease of applying CPT's proprietary conductive mastic, installation costs are lower than comparable impressed current cathodic systems utilizing sawslotting or overlays.

Easy access to anodes, mastic and control systems ensure future low cost maintenance the competition just can't match. Consequently, CPT's reliable performance, customer satisfaction and proven history are unequaled.

"There is no question that properly installed and activated cathodic protection systems halt corrosion and corrosion induced concrete damage in salt-contaminated above ground reinforced concrete structures.”

The C2A carbon mastic anode provides an unsurpassed technology to cathodically protect balconies and similar structures. Years of monitoring actual current densities have indicated low output values on average of
.50 mA/sq ft. What this means to you is vastly longer life expectancy.
