Round posts and agricultural fencing
Round posts have been associated with agricultural fence installations for many years, but since the late 1990’s fence posts started to fail after 3-4 years. This happened at a time when the chemical constituents of the preservatives had been changed. It transpires that the new eco-friendly chemicals were kinder on the environment but also less effective on controlling fungal decay and insect attack. .
The UK‘s increasingly warmer and wetter weather has made conditions damper and easier for insects and timber rotting bacteria to survive. However, progress in timber preservatives imeans that a 15-Years Guarantee is realistic providing that the Permapost Incised posts are used correctly -see here
Pressure treating the posts

The treatment process begins with the timber being kiln-dried to reduce the moisture content down to around 28%. The preservative is then added to the timber in a high-pressure vacuum to achieve deeper penetration of preservative. The intense treatment is intended to extend the post’s life to approximately 15 years.
