Cu-Bor is a Copper/Boron wood preservative, used to treat the groundline area of standing wood structures such as utility poles. The highly effective active ingredients in Cu-Bor travel deep into the wood by diffusion (osmotic action). Cu-Bor's labeled uses include:

  • Brush-on
  • Spray
  • Dip/Diffusion
  • Pressure Treating

Cu-Bor is also a furnish treatment in engineered wood products and a railroad tie treatment. Cu-Bor is available in bulk and ready-to-use packaging.

Remedial Treatment

The principal cause of pole failure is decay, and the most common area for decay to occur is that portion of the pole from approximately 2 inches above groundline to approximately 18 inches below. The most accurate pole inspection method is to excavate this groundline area. For a marginal cost pole-owners can extend the service life of their poles by applying Cu-Bor externally and wrapping it with a moisture barrier before the excavation is closed.

Wood, however, is a biological commodity that can undergo deterioration by insects, decay fungi, termites, and mechanical destruction. In many ways wood poles, can outlast materials constructed of synthetic materials like concrete, fiberglass, steel and aluminum if well maintained and cared for in a consistent and timely manner.

Efficacy of Copper Borax Preservative Against Wood Decay

In this study, a wood preservative containing active ingredients of 43.5% borax and 3.1% copper hydroxide was evaluated in soil-block tests in accordance with AWPA E10. Results suggested that the copper hydroxide was not contributing to fungal toxicity at preservative threshold levels. Thresholds determined for this preservative were very close to those previously reported for sodium borate. For this preservative, the soil-block test results in this study were less effective than field test results.
Introduction
For centuries, wood has been treated with a variety of organic and inorganic additives to protect it from bacterial, fungal, and insect decay (Warner and Solomon, 1990). Copper has been one of the most widely used ingredients in wood preservatives because of its fungicidal properties. But because some fungi are resistant to copper...

 Cu-Bor has two active ingredients: copper hydroxide and sodium tetra borate decahydrate (Borax). The Copper and Boron in these two molecules have very low mammalian toxicity. Accidental or inadvertent worker exposure is unlikely to cause serious or irreversible injury. Cu-Bor is registered by United States Environmental Protection Agency as a pesticide against wood destroying insects and decay fungi. Cu-Bor exhibits volatile organic compound (VOC) content at less than one-sixth the limits defined by South Coast Air Quality Management District (SCAQMD) for the wood preservative category of SCAQMD Rule 1113.Cu-Bor is fully compliant with all EPA and SCAQMD requirements.
