product from this company that they advocate for use in tree wells, is "Addaset"
I believe. It appears to be a mixture of fine pea gravel with epoxy
resin. The City of Vancouver used to used to do this (they mixed up their
own recipe) with tree wells in their downtown area. It's very attractive
and seemed to keep weeds etc out of the tree wells but I heard that they were no
longer using it in tree wells. I think the reason was that eventually the
product was lifting up and becoming cracked and chipped and it became a tripping
hazard.</FONT></SPAN></DIV>

recycled crumb rubber product that is bound up with resin, but it also allows
air and water to penetrate. I saw this at the Western Chapter ISA meeting
earlier this year. Has anybody tried this? It probably would not
crack or lift up the same way. We've used the rubber sidewalk pavers
around trees for a few years now, with good success, but I thought this "pour in
place" idea was neat. Here's a link: <A

<P><FONT face=Arial size=2>Hello I was just wondering if anyone has experience
with tree well systems such as "chameleon ways" as advertised in the arborist
magazine. I am looking to see if they are affective and available by a
Canadian distributor</FONT></P>
