Welcome aboard, Rancher, I guess we can use that for a first name? :)

Problem with the treated wood for curbs is that it is gonna shrink, which is not a good thing. Before the big guys tell you to tear it out, measure the width of the 2x4 (the alleged 4" dimension) and tell us what you got. Measure accurately to the sixteenth of an inch. If your boards are in the 3 5/8ths inch range, you'll need to wait many sleeps before they're done shrinking. If, on the other hand, they are closer to 3 1/2 inches, you may not have much of a shrinkage problem.

But the big question is: You got you a Sawzall? :p

Mmmmm, those 2x10 joists aughta be only about 9 1/4 if they're typical, Rancher. In today's wood, if they're over 9 inches fully dry, you gotta use'em anyway. :(

Drill a hole a half inch or larger down into that curb and see if you hit water (serious, here). New treated wood, unless it is marked as KDAT (Kiln Dried After Treatment), will have visible moisture in the center - you can frequently squeeze water from the shavings. If your plates are that wet, I'd cut'em out. If they're not, and they measure close to 3 1/2 inches wide, I'd probably leave'em. But I might also get some flack over that part of the advice. :)

Hi Rancher, Welcome. :)

The problem might not be the shrinkage, but many times when that stuff shrinks, it twists and turns. Peel the liner back out of the way and get the stuff out of there.

Where's the ranch?:monster:
