Marc: We are using "Lifetime" treatment on wooden grade beams based on the
confidence that Parks Canada has gained with this non-toxic wood finish.If
the utility company is in the 1990s, they would be happy to try this
method of preserving wood even below grade.It comes as a powder (easy for
shipment). Water is added on site. It is a preservative "preventing decay
for 50 yeears and more. It will outlast even pressure treated wood." If
interested, your friend may wish to call Oke Wictorim of Valhalla Wood
Preservative Ltd. at (403) 228-5193.
