your point, as these are made from recycled rubber tires. Will these tree

alternative - to landfill the used tires?<o:p></o:p></span></p>

<p class=MsoNormal>FYI - This might be of interest to other urban foresters.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We have a lot of open “tree wells”, they are
usually 4 or 6 feet square tree pits in hardscape without a tree grate, and
weeds have been an on-going issue. Especially now that we don’t
spray pesticides much anymore. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal style='margin-bottom:12.0pt'>We’ve been looking for
some alternative solutions for a few years now. One product that we have
tried that seems to work pretty well are the recycled rubber tree rings but of
course the problem is that they are round and don’t come in the right
sizes. Recently we were able to find a manufacturer who is going to
custom make some large rubber tree mats for us. These are 100% recycled
rubber, LEED certified, they come in a variety of colours and I believe they
are porous so they allow water and air to pass.<o:p></o:p></p>
<p class=MsoNormal>We’re going to try some out. In case others are
interested in trying this, here’s what we’ve been quoted by
Eco-Flex out of Alberta (<span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>shekhar@telus.blackberry.net)</span>:<o:p></o:p></p>
