CathFlow® for foundations

The CathFlow® ICCP system is designed to cathodically protect underground building foundations. An effective way to extend the lifetime of building foundations.

CathFlow® ICCP material package

CathFlow® ICCP system has the ability to cathodically protect any underground building foundations, regardless of size and number.

The CathFlow® ICCP package consist of control panel, ICCP anodes and reference cells.ICCP material package for building foundations

The CathFlow® control panel can be connected to any kind of ICCP anodes and reference cells, and includes the following features:

  • Durable accurate operation
  • Multiple output channels with individually adjustable output effect
  • Flexible system with expandable number of outputs and control unit effect
  • User-friendly operation
  • Automatic logging
  • Prepared for remote control and monitoring

The most commonly used anode for underground building foundations is the high silicon iron anode in canister. See the full range of ICCP products.

ICCP explained

Impressed current cathodic protection (ICCP) systems have the benefit of an external power source to impose protective current. This makes it possible to protect any buried structure, regardless of size and current requirement, by using long life anodes and appropriately sized power supplies. You may also want to read about design of corrosion protection for underground building foundations.

The most important feature of an ICCP system is the ability to continuously monitor the level of protection and adapt to the current required to stop corrosion. Learn more about the principles of cathodic protection.

Installation

The anodes can be installed by excavating or core drilling through the building basement. In some cases, assumed low risk for interference with other structures, the anodes can be buried outside the building. The number of anodes depends on the area to be protected and the expected current distribution. Reference electrodes should be installed close to some of the steel foundation piles to measure the effect of the cathodic protection at certain locations.

In order to ensure cathodic protection for all steel foundations under the entire footprint of the building, all steel piles have to be electrically interconnected.

Operation

The CathFlow® ICCP system can be operated either manually, by a fixed current or voltage output, or automatically controlled by one or more measured reference potentials. Either way, the system will maintain adequate cathodic protection. You may also want to read about how to follow-up ICCP systems for building foundations.
