The fence delineating the FPInnovations – Forintek Division test site at Maple Ridge, BC was designed to be functional, but also to incorporate a study to determine whether a physical barrier between the soil and wood surface, in the form of a wrap, would affect the performance of ACQ-treated lodgepole pine roundwood in ground contact. After five years in the field test, the fence posts treated with two formulations of ACQ, both wrapped below ground up to the groundline and non-wrapped, remained sound.
