Postsaver is a UK manufacturer and global leader in timber ground-line protection, dedicated to extending the service life of wood in ground contact. For more than 30 years, our patented dual-layer barrier technology has helped protect timber posts from premature ground-line decay, with over 10 million posts protected worldwide.
The greatest threat to the longevity of timber posts occurs at the ground line, the critical air-to-soil interface where moisture, oxygen and fungi create the ideal conditions for fungal decay. More than 90% of timber post failures occur in this vulnerable zone. Postsaver rot protectors are specifically engineered to protect this critical area, creating a durable barrier that helps prevent moisture ingress and significantly extends the life of timber installations.
Manufactured in the UK to stringent ISO 9001 quality management standards, Postsaver products have been independently tested and proven to perform in some of the harshest ground conditions. They are also approved by the International Code Council (ICC), demonstrating compliance with internationally recognised building standards and giving architects, landscape professionals and specifiers confidence when selecting timber protection solutions.
Trusted by landscape architects, contractors, local authorities, and trade professionals, Postsaver helps maximise the lifespan of timber installations while reducing maintenance requirements, replacement costs and environmental impact. By maximising the service life of timber, Postsaver supports more sustainable construction through reduced material consumption, lower embodied carbon and fewer replacement cycles.
The Postsaver range provides long-term protection for a wide variety of applications, including fencing and landscaping, and structural timber projects including gates, decking, pergolas and signposts. The Postsaver Standard Rot Protector is backed by a 20-year post replacement guarantee, while Postsaver +PLUS offers a 40-year post replacement guarantee, giving specifiers and clients confidence in the long-term durability and performance of their timber installations.
