For a robust and dependable fencing solution, look no further than these rot-protected and UC4 treated posts. Crafted from premium timber, each post benefits from pre-applied Postsaver rot protection, guaranteeing longevity and peace of mind with a 20-year post-replacement guarantee.Backed by over 20 years of independent testing by the BRE, Postsaver's innovative dual-layer rot prevention technology provides a proven defence against ground-line post rot. This technology works by forming an airtight and watertight seal around the post's surface, effectively blocking the elements necessary for wood decay: fungi, oxygen, and moisture. Since the sub-surface soil lacks sufficient oxygen for fungal survival, protection below this level is unnecessary.Install these posts using standard methods; they are fully compatible with fence post concrete, backfill, and power-driving. Invest in a lasting fencing solution with these posts, sized at 100 x 100mm x 2.4m (approximately 4 x 4" x 8ft). Each UC4 treated wooden fence post comes equipped with a Postsaver Pro-Wrap Rot Protection Shield, ensuring a 20-year post-replacement guarantee and rot protection extending to a 30cm (2ft) burial depth.
