IMPEL Rods offer a unique and effective preservative system for the prevention and control of internal decay in log and timber structures. They are a highly concentrated, solid form of water-diffusible borate.

IMPEL Rods are ideal for both prevention treatments of high risk areas (hot spots) and remedial treatments in areas with existing decay. They are an EPA approved, low-cost, environmentally responsible way to stop rot and decay—from the inside.

IMPEL Rods are easy to use and can be applied at the time of log production, building construction or in existing structures.

IMPEL Rods install in three easy steps: (1) drill appropriate sized holes to accommodate rods; (2) insert IMPEL Rods into the holes; (3) plug the holes with a quality caulk such as Log Builder.

IMPEL Rods are available in a wide variety of sizes to fit your particular application.
