Electro Tech CP EOP™:
Electro Osmotic Pulse

Electro Tech CP EOP™ is a proprietary electro osmotic system that controls movement of water through concrete under the influence of a pulsating electric field. An electrochemical solution, this state-of-the-art technology has been engineered by STRUCTURAL TECHNOLOGIES for various applications to control moisture and corrosion in concrete.

In selected applications, this patented system provides the ability to mitigate chronic moisture problems in concrete – by lowering moisture transmission and content through concrete’s pore and capillary structure. It can be used alone, or in conjunction with other moisture control solutions to extend the service life of concrete.

Utilizing advanced controllers and components found in Electro Tech CP™ Impressed Current Cathodic Protection Systems, Electro Tech CP EOP™ also provides the ability to eliminate, or slow corrosion of reinforcing steel in concrete.

Electro Tech CP EOP™ is also being developed as a solution to other concrete issues. STRUCTURAL TECHNOLOGIES is testing the system as a means to mitigate alkali-silica reaction (ASR) in aging concrete. ASR is a destructive process that can lower a structure’s strength and capacity and significantly impact its effective service life.

The Electro Tech CP EOP™ Dewatering System includes four main components:

• Controller
  Utilizing our proprietary Electro Tech CP™ advanced controllers and software, a safe, low-voltage DC electric field is applied between the anodes and cathodes and through the structure, while also monitoring system performance and allowing for adjustments to be made to the system through a remote connection.
• Anodes:
  Probe, mesh, surface applied or other anodes establish a positive electrical charge inside the structure being protected.
• Cathodes:
  The tips of copper-coated rods carry the negative charge and are strategically placed outside the structure being protected.
• Reference Cells & Probes:
  Placed within the structure, these probes continuously monitor and regulate such parameters as moisture levels, temperature, voltage, current and corrosion potential.
