Telecommunication towers around the world allow
millions of wireless service users to communicate. These
towers are an essential component in our daily lives – both
personally and professionally. The structural integrity of
these towers is regularly maintained for both operational and
safety reasons. In Canada, the CSA Group (CSA) Standard S37,
Antennas, Towers, and Antenna-Supporting Structures, typically
applies to the design, manufacture, installation, inspection
and maintenance of these types of towers. Also included in
CSA Standard S37 are requirements for corrosion protection.
Corrpro has been working with telecommunication companies
for decades to help ensure integrity of their towers by
protecting below-grade steel, primarily in anchor points,
Typical guy-wire-supported telecommunication towers are
approximately 300 feet tall and require three to six anchor points
to keep the tower upright. The integrity of these steel anchor
points must be maintained, in part, through the application
of effective corrosion control. On many tower sites, cathodic
protection is included as part of an overall corrosion control
program. In Alberta alone, Corrpro has installed cathodic
protection systems at over 400 telecommunication tower sites.
TYPICAL TOWER SITE, TYPICAL TOWER
In 2017, Corrpro was contracted to conduct cathodic
protection maintenance investigations at a large number of
tower sites throughout Alberta. Over 200 tower sites were
investigated within a very short time period, with updates
provided to the client daily. The investigations included soil
analysis, interference investigation, “ON/OFF” potential
surveys and full analysis reporting.
Along with the investigation, Corrpro was also tasked with
remediation of cathodic protection systems at 41 tower sites.
This remediation work included test station repairs, broken
cable repairs and new groundbed installs. Of the 41 tower sites
requiring remediation, 29 sites required new groundbeds and
12 required repairs.
In alignment with Aegion’s value, RESULTS MATTER, Corrpro
provided timely expert services to keep our customer’s
telecommunication towers working better, safer and longer.
