UC4 (Use Class 4) treatment means the sleeper is suitable for direct ground contact or freshwater exposure, such as in retaining walls, garden edging, or raised beds.

“Incised” means the timber has been mechanically scored with small incisions before pressure treatment. This allows deeper and more even preservative penetration, improving durability and lifespan when used in-ground.

It comes with a 15-year guarantee against rot and decay when used as recommended—thanks to the enhanced UC4 treatment and incising process.
