Pressure treated question

[RobA]

</font><font color="blue" class="small">( I put it on concrete piers formed by using sonotubes. I put a 12 inch diameter pad 6 inches thick and 2 feet underground for the footing, and when that dried, I poured 6 inch diameter piers using the sonotubes. Everything was tied together with rebar. )</font>

I assume you didn't need enough concrete to have a truck deliver it. Did you mix the concrete yourself? Electric or gas mixer? Easy project?

Are these the ones you can get at Lowe's?

Rob,

Check you state rules on using ACQ. Since the change form CCA, which was BS, most of the PT wood is ACQ. As others have said you can still get CCA for professional use. But see if ACQ is treated, pun intended , rule/law wise as CCA PT. ACQ might be viewed differently and you might be able to use it.

Later,
Dan

And if you do use ACQ, be sure to use stainless or hot-dipped fasteners, since the treatment will eat up bright fasteners in only a few years.

I would go with posts larger than 4" simply for the durability. In salt water around here (NW FL), marine treated posts really get eaten up at the water line. Bigger lasts longer. I don't know about fresh water, but I suspect that bigger is still better.

Creosote lasted about 30 years in salt water here, CCA about 20, so who knows how fast ACQ will get worm-eaten?

I don't know what your local power company uses, but I can get used poles for free from mine. I also don't know what treatment rating they have, but most of them still have the tag on them. I have never seen a pulled one with any termite (or any other) damage. I used some for a gazebo foundation, saving well over $1000 in concrete/pumping costs. If they are free, you might just live with them.

Good Luck!
