A system for replenishing embedded foundation preservation wraps with preservative comprises an embedded foundation, a preservation wrap, and injection apparatus configured to be inserted between the wrap and the foundation. The injection apparatus includes a profiled backing plate and a semicylindrical tube portion defining a lumen therebetween, with a preservative inlet and a plurality of outlet nozzles along a distal bayonet fronting portion. A syringe with a reciprocating plunger operates within the lumen to enable controlled delivery of preservative and purging of residual preservative after use. The plunger may be locked in retracted, inserted, or blocking positions to manage flow and prevent leakage.

An antimicrobial HVAC filter is designed to be installed in conventional HVAC systems and has conventional filtration material. The filter has antimicrobial enhancement by way of a copper screen and an ultraviolet light source laid flat across the copper screen. The copper provides toxic oligodynamic effect on living cells, algae, molds, spores, fungi, viruses, prokaryotic, and eukaryotic microorganisms. The ultraviolet light source provides germicidal ultraviolet (such as ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA.

A woodpecker deterrent system for a timber utility pole is disclosed. The system comprises a reflective panel assembly configured to be applied around a portion of the timber utility pole and a plastic sleeve that is heat-shrunk to encapsulate the reflective panel assembly. When installed, the reflective panel assembly and the heat-shrunk plastic sleeve form a plurality of reflective panels around the timber utility pole. The reflective surfaces create a visual deterrent by producing multiple reflections of the surrounding environment, which woodpeckers perceive as the presence of a rival bird, discouraging them from pecking the pole. The plastic sleeve secures the reflective panel assembly in place while also providing environmental protection, ensuring long-term durability. The system is designed for ease of installation and does not require chemical treatments or moving components, offering a low-maintenance and non-toxic solution for mitigating woodpecker damage to timber utility poles.

A method of preserving the aboveground section of a timber utility pole includes treating the pole with a wood preservative, heat-shrinking a plastic sleeve around the pole to encapsulate the preservative, and storing the pole horizontally prior to installation. The plastic sleeve protects the pole during storage by reducing preservative volatilisation and migration. The pole is installed vertically in its encapsulated state, with the sleeve covering at least the aboveground section to shield it from environmental degradation such as rain and sunlight. Additional plastic sleeves may be applied to enhance durability, including during long-term use. The method provides a protective barrier that maintains the structural integrity and preservative efficacy of the pole while allowing for efficient handling and installation.

A process for preserving timber rail crossties involves an initial treatment with an inorganic borate wood preservative, followed by encasement in multiple plastic sleeves. The chosen preservative is effective against various pests and has lower toxicity than traditional options like creosote and CCA, addressing health and environmental concerns. Although the preservative's water solubility raises potential leaching issues, these are mitigated by wrapping the treated crossties in several differentiated plastic layers. The inner layers adhere to the wood, while the outer layers interface with the smoother inner surfaces, enhancing durability and preventing preservative leaching. End caps at the crosstie ends may further seal the wood, creating a preservative reservoir for slow diffusion and allowing for periodic replenishment, which extends the crosstie's lifespan and maintains structural integrity through innovative design.

The present injection apparatus is designed for replenishing embedded foundation preservation wraps with preservative whilst avoiding spillage. The injection apparatus comprises an injection bayonet having a lumen fluidly interfacing a plurality of preservative outlet nozzles along the injection bayonet and a preservative inlet fluidly interfacing the lumen. A portable preservative containing tank may be attached to the inlet via a flexible hose. The apparatus further comprises a syringe operating between the preservative inlet and the lumen. When replenishing the preservation wrap, the injection bayonet is inserted between the preservation wrap and the foundation so that preservative is configured to be supplied via the preservative inlet to flow out from the nozzles via the lumen to replenish the preservation wrap with the preservative. After replenishment, the lumen is purged of residual preservative using the syringe.

A passive cathodic protection process for preservation of embedded metallic foundations entails embedding a wrap around a metallic foundation. The wrap has an outer sheath and an inner absorbent mat to be in direct contact with the metallic foundation. The is also mat hydrophobic. The wrap is subsumed such that an upper edge of the wrap is accessible. An oil-based metallic soap is injected via the upper edge to impregnate the mat. The metallic soap is selected from a set of metallic soaps such that the metal of the metallic soap is more electropositive than the metal of the metallic foundation such that the metallic soap acts as an anodic solution for galvanic exchange with metal within the embedded metallic foundation for the passive cathodic protection thereof. For example, zinc naphthenate may be selected for steel or aluminium foundations thereby allowing for both passive cathodic protection and biocidal action.
