Pressure treatment pushes preservative deep into the sapwood. Brushing it on does not.
A pole fails at the ground line, where moisture, oxygen and termites meet. Pressure treatment drives preservative into the sapwood under vacuum and pressure, so the protection is inside the wood rather than painted on it.
At the Nyanza plant UFCL treats poles with CCA (copper chrome arsenate), the preservative used for the poles we supply to Rwanda Energy Group and electrification contractors. Treatment standard, retention and the classes UFCL supplies: [Confirm].
