Panel Joint Maintenance

Panel joint maintenance should not be overlooked
Allowing panel joint sealants to fail and remain in a failed state can cause a wide range of issues to the asset as well as keep energy costs running higher than they should. Sealant joint maintenance should be part of any concrete structures general building maintenance plans.
Water Infiltration: Unsealed joints allow water to penetrate the building envelope. Over time, water infiltration can lead to structural damage, corrosion of reinforcement, and deterioration of the concrete.
water is easily penetrating the building walls
Corrosion of Reinforcement: Moisture entering through unsealed joints can reach the steel reinforcement within the concrete panels. This can lead to corrosion of the reinforcement, compromising the structural integrity of the building.
Additional issues that can arrise from failing panel joints.
Mold and Mildew Growth: Moisture ingress provides a conducive environment for mold and mildew growth. This not only affects the aesthetics of the building but can also lead to health concerns for occupants.Efflorescence: Unsealed joints may allow soluble salts to migrate to the surface of the concrete, leading to efflorescence. This is the formation of white, powdery deposits on the surface, which can negatively impact the appearance of the building.Reduced Thermal Performance: Improperly sealed joints can contribute to heat loss or gain, affecting the building’s energy efficiency. This can result in increased heating and cooling costs for the occupants.Air Leakage: Unsealed joints can allow air infiltration, impacting the building’s indoor air quality and making it more challenging to maintain a comfortable and controlled environment.Structural Instability: Over time, the combination of water damage and corrosion can compromise the structural stability of the building, potentially leading to safety hazards.
