Borate Rods are an easy, low-cost decay protection and prevention system for wood. They have an appearance similar to glass rods and are available in a variety of sizes for a wide range of applications. Borate Rods are molded from fused; water-diffusible borates which are internationally recognized as an effective and well established wood preservative. Borates also effectively control termites, carpenter ants, a variety of beetles, and many other wood boring insects. They are user friendly and environmentally acceptable. Borates are highly toxic to fungal decay and many insects at concentrations that are not poisonous to humans or other mammals. Borate Rods are an important part of System Three Resins' EndRot System for wood rot repair. For more details about the EndRot System, read our Wood Restoration page.
Rods are placed into holes drilled in wood at key locations. As the rods dissolve, the borate preservative migrates to areas of highest moisture and concentrates where wood is most susceptible to decay. If the wood dries the rods stop diffusing. The residual preservative remains in place. When the moisture content rises the rods resume diffusion. Depending upon conditions of moisture, rods need not be replaced for years. A chart included in each package that shows recommended rods sizes and spacing for each type of installation. There are three easy steps to installing Borate Rods:

Borate Rod Diffusion
When a piece of wood gets wet, Borate Rods will diffuse, stopping any further decay.

Bor8 Rods are a registered pesticide in both the USA and Canada.
Use Borate Rods in all areas where wood is exposed to moisture. These high exposure areas include:
Flooring and Foundation Systems: The greatest risks for decay are at exposed wood end grain and at wood joints where moisture is more readily absorbed than on side surfaces. Other areas of concern are where joists rest on block piers; at band sills around dirt-filled porches; at untreated deck headers; and at foundation sites near chimneys.
Window and Door Framing: Anywhere weathering of paint and exposure has occurred especially at the bottom of windows and doors is at risk of decay.
Exterior Steps, Porches and Decking: Install Borate Rods in posts, rails, wood ends, joints and trim.
Roof Trim and Facia: Facia boards supporting gutter systems and soffits are especially vulnerable to decay attack. Also protect areas where trim is in contact with skylights, vents, chimneys and where excessive moisture is common.
Roof and Attic: Install Borate Rods where leaks have caused water damage to support members and rafters.
Log Construction: Borate Rods should be installed wherever logs are not protected from the elements.
Poles and Posts: Install Borate Rods where moisture may cause decay; especially in building and foundation poles; and farm and residential fence posts.
Installation of Borate Rods is an important preventative step in System Three Resins' EndRot System for wood rot repair.
