<p style='margin-bottom:12.0pt'><span style='font-size:10.0pt'>I think you have
a good case to get them to replace at their expense. However we have
stopped using weed barrier entirely. We found that it keeps the weeds
down for a few years but eventually the weeds invade the mulch and when you try
to pull them it pulls up the cloth and becomes a big headache. We just
control weeds the old fashioned way, pull by hand or till with hand tools<br>

Subject: [CANUFNET] Anyone have experience with various weed barrier fabrics?<br>
<br>
Some Background:<br>
A contractor installed 3 oz woven polypropylene landscape fabric in a large,
irrigated, raised median, whereas the contract specs called for 3 oz spunbonded
polypropylene. Spunbonded was specified due to its better air and water
permeability (min. 100 gal/min/sf) whereas the woven material has less than 15
gal/min/sf. The planter has a drip irrigation system, and to aggravate the
matter, the irrigation lines were laid on top of the woven material. Water is
pooling on the tarp-like woven material.<br>
<br>
The contractor refuses to replace the non-approved material with the spec'd
material, claiming it "exceeds" the specifications. It may exceed the
spec in terms of strength, but the critical characteristic of permeability has
been compromised.<br>
<br>
The questions are:<br>
1) Will the woven, less permeable material cause problems with plant growth and
survival (trees and perennials), or can we live with it - with the drip lines
on top if it?<br>
<br>
2) What are your experiences with spunbonded (or non-woven) weed barriers vs
woven?<br>
Thanks<br>
