Yes, I know you can use hardwood sleepers. However, termites can eat those, too. I know that's not very likely, but DH and his family (who own this house) are paranoid about termites. Understandably so, after having to pretty much rebuild 2 houses due to termites within the last 10 years or so (his parents own a bit of property).
Also, hardwood sleepers are so much more expensive. although I do love the look of them and certainly like the idea of being able to sit on the edge.
So, does anybody have any thoughts on the ACQ treated pine?
