Tanalised timber - lifetime?

[cmhicks]

Hi All,

Following some groundworks to relay the drains crossing the garden and to lower the ground level, I need to make a retaining edge for some gravel, about 6 inches high and four feet long. The easiet aesthetically acceptable solution would be a tanalised board supported by maybe 2x2 tanalised posts driven into the ground. How long could I expect such an arrangement to last before the rot gets it?

cmhicks,
Depends how good the tanalised timber is but expect the rot to start in some areas in about 5 years.

Thanks, that's about what I thought.
