photo) installed under new concrete sidewalks where tree wells have also been installed?
The idea would be to install the multi flow tubing so that it radiates out from
the tree well to allow for gas exchange. Granted there are numerous concerns associated
with tree wells in general, but any thoughts on the effectiveness of the multi
flow tubing?<o:p></o:p></span></font></p>
