Borates for Woodworm and Dry Rot eradication
Compounds of Boron, chemically known as Borates, have been mined since the 1800s and have been used to control insect pests for over 100 years.
Boron was discovered in the USA in the late 1800's and first mined by Francis M 'Borax' Smith in 1872 as the crystalline material 'tincal', which contains about 50% borate.
Purified and sold throughout the world in vast quantities as Tim-bor Professional, it poses a low risk to the environment, especially when compared with other current pesticides, particularly because of its lower toxicity to fish. Now backed by more than 100 years of research and development, it is manufactured in the USA by Rio Tinto Borax, based in Valencia, California.
By the 1940s Borate formulations were being used to protect wood. Because they are water soluble, Borates diffuse into wood using the wood's own moisture (even 'air dry' timber has a moisture content of 12-15%) and they protect against woodworm, Death Watch beetle, House Longhorn beetle, Termites, Carpenter ants and fungi, including Dry rot.
For well over 60 years Borates have been in successful use in Europe, Australia, New Zealand and the USA. Borates are used in dusting, foaming, spraying, brushing and pressure treatment applications. Other major uses include: glass production, detergent preparations, enamel and ceramic glazes.

TIMBER & MASONRY TREATMENTS
Introduction to Boron Use
Borons are fungicidal and insecticidal treatments manufactured from Inorganic Compounds of the Element Boron. They prevent insect attack and eradicate Dry rot in timber, being mobile in dry timber. They allow the use of the ZERO CUTBACK OPTION - no sound timber need be removed beyond the physically damaged zone. They also provide permanent protection, as the active ingredient does not break down or evaporate.
WORLDWIDE BORON USES
Over 50 years of successful use in Europe, Australia, New Zealand and the USA. Used in dusting, foaming, spraying, brushing and pressure treatment applications. Other major uses include: glass production, detergent preparations, enamel and ceramic glazes.
PENETRATION OF BORON PRODUCTS
Even when applied in its most basic form, as a solution (up to 12.5% active) in water, Borates penetrate a minimum of 2-3 mm in 'DRY' timber and more, depending on the moisture content of the timber. In conjunction with Glycols, as gels and pastes (in concentrations of up to 50%) penetration increases dramatically. These more expensive products are designed for situations where deep seated decay requires high below-surface concentration of the active ingredient. This is not required, or desirable for normal Common furniture beetle spraying.
DURABILITY OF BORON IN WOOD UNDERGROUND
Boron remains inert in the timber, providing protection long enough for Railtrack to have specified it for Railway Sleeper protection and Scottish and Southern to have specified Boron rods for the preservation of their electricity transmission poles.
