MATCO MAINTAINS AND REPAIRS ELECTRIC POWER TRANSMISSION TOWERS FOR UTILITIES

 

Overhead transmission, distribution and substation support structures are often in need of repair to ensure the safety and reliability of these critical assets. Typical risks include corrosive environments, ingression of water and moisture on internal surfaces and mechanical damage from poor installations or accidents.

The ingression of water and other forms of moisture into the internal areas of tubular shaped (pole) structures that are sealed at the interface of the base plate and concrete foundation is considered one of worst case scenarios for these structures in terms of corrosion. This form of corrosion is especially harmful as there are no observable signs that accelerated corrosion is taking place, such as the appearance of red rust staining, pitting or metal loss, that are typically used as indicators.  MATCO offers trained technicians experienced in baroscopic inspections and electrochemical corrosion testing.


The methods used for repair include, among others, retrofitting with hand hole access, adequate draining source installation, fitting of steel repair plates and welding of new plate to existing shafts.  Customized cathodic protection solutions can stop the corrosion process and provide additional years of service to your assets.  In addition, MATCO offers custom coating solutions to protect and extend the life of damaged or existing structures. All repair procedures are performed by NACE certified technicians that have undergone extensive training in steel utility pole, lattice, tower and anchor rod corrosion assessment and mitigation techniques.  All welding is performed by AWS and CWB certified professionals.  Non-destructive testing is performed by certified ASNT professionals.
