Case Study SSE Muff Coating

Location: Burghmuir, Scotland Customer: SSE Date: Sept 2014 Weather: Dry Oxifree UK were asked to partake in a trial coating of the concrete “muffs” at the base of electricity pylons to provide an environmentally safe, long term solution to the ongoing degradation of the concrete structure caused by moisture ingress. The “muff” is a thick concrete support that bares the weight of the pylon and is the interface between the pylon and the earth. Historically, the “muffs” have been coated in bitumen, which is environmentally hazardous and dangerous to livestock. The objective was to provide an alternative to the bitumen coating currently used as this technique is proven to be ineffective over the long term. The capillary action of moisture ingress eventually cracks the concrete, leaving the structure unable to support the weight of the pylon. Oxifree was also selected to protect the pylon “muffs” and additionally, the legs of the pylon to prevent eventual corrosion of the structure. Process Step 1 of the process was to obtain approval for use by the Animal Health and Veterinary Laboratories Association (AHVLA) approval for the use of Oxifree within a livestock inhabited environment, which was achieved. An Oxifree UK team attended a power station in Scotland where the pylon “muffs” already showed signs of degradation and at a location where ongoing evaluation of the coating performance was achievable. The application of Oxifree TM198 was achieved in 1 day, whereby the pylon “muff” was protected and the area deemed safe for livestock and site personnel. Oxifree Case Study Introduction Objective

Oxifree UK were asked to partake in a trial coating of the concrete “muffs” at the base of electricity pylons to provide an environmentally safe, long term solution to the ongoing degradation of the concrete structure caused by moisture ingress.
The “muff” is a thick concrete support that bares the weight of the pylon and is the interface between the pylon and the earth. Historically, the “muffs” have been coated in bitumen, which is environmentally hazardous and dangerous to livestock.
The objective was to provide an alternative to the bitumen coating currently used as this technique is proven to be ineffective over the long term. The capillary action of moisture ingress eventually cracks the concrete, leaving the structure unable to support the weight of the pylon. Oxifree was also selected to protect the pylon “muffs” and additionally, the legs of the pylon to prevent eventual corrosion of the structure.
Process Step 1 of the process was to obtain approval for use by the Animal Health and Veterinary Laboratories Association (AHVLA) approval for the use of Oxifree within a livestock inhabited environment, which was achieved. An Oxifree UK team attended a power station in Scotland where the pylon “muffs” already showed signs of degradation and at a location where ongoing evaluation of the coating performance was achievable. The application of Oxifree TM198 was achieved in 1 day, whereby the pylon “muff” was protected and the area deemed safe for livestock and site personnel.
Oxifree Case Study
Introduction
Objective
Project The project involved the use of Oxifree Polymelt 50 application unit and external generator to provide power, as due to location of the pylon onsite power was not available. The area was prepared to a depth on 120mm around the concrete, then the structure was cleaned using warm water only, to remove dirt and debris build up. Once dry, Oxifree TM198 was applied at the base of the concrete and along the pylon upright together with all periphery support beans to a height of approximately 500mm. An application of silicon mastic was applied to the interface to secure the coating and prevent removal by wildlife. The actual coating time was completed within 4 hours allowing normal operation of the power station to resume shortly thereafter.
