The Copper is for stopping funcal decay and rot and the the arsenic to stop termite/borer infestation. The Chrome binds the other agents together in the timber. ACQ stands for Alkaline Copper Quartenary. This treatment contains about 5 times the amount of Copper as CCA and the 'jury'is still out on its potential to leak copper into the soil. The Quartenary chemicals are used in lieu of arsenic to repel termites and boreres. ACQ sleepers/ logs etc are generally about 75% dearer than their CCA counterparts Re: ACQ treated pine: what does this mean? 8Aug 14, 2009 6:56 pm oztish In short, the ACQ is better for the environment than the CCA in terms of future potential to pollute. Actually no, and possibly the opposite in fact. Copper leaching from ACQ treated timber into a vege garden for example would be far worse. Re: ACQ treated pine: what does this mean? 9Aug 14, 2009 7:49 pm Here's the website I found http://www.rainforestinfo.org.au/good_wood/pres_not.htm Quote: Copper Chrome Arsenic (CCA) Please don't use this stuff! Try and change your plan of approach and use recycled or plantation-sourced hardwoods if you must have exposed timber3. If you must use non-durable hardwoods or softwoods, try and use them only for internal applications, where borax4 treatment and/or painting, will suffice to protect them. This is the only way we will avoid the ever-escalating problem of how to dispose of CCA-treated timber at the end of its useful life. Even treated pine decays and has to be replaced sometime - usually after about 20 years of service-life. Burning or burying the discarded timber will pollute either the sky or the earth. Suggestions to use it as chicken litter or mulch around trees should be shunned! CCA-treated timber at the end of its useful life is toxic waste. We have been told by VicUrban to use the ACQ timber and not CCA. We used the CCA hoping they don't notice or ask (I only found their email after we finished the garden)! Re: ACQ treated pine: what does this mean? 10Aug 14, 2009 8:31 pm The lesser of two evils perhaps Either will do the same job. I think where H3 applications suit, people should buy LOSP treated pine (Light Organic Solvent Preservative) This would include deck joists, bearers, rafters etc. Its available in the traditional 'rougher-header finish (all the lines and same price as CCA)) or smooth pre-primed (unfortunately quite exspensive). This is a safer enviromental choice, its a shame it can't treat to H4 or stronger levels. DIY, Home Maintenance & Repair Are you going to have the frame exposed or are you cladding it with something.
