not specifically. i used to get free samples all the time from vendors, target audience being environmental remediation folks and landfills. i'll see if i can dig up a couple names and send you a PM..might be a day or two, you in a hurry? my older files are archived in the attic
otherwise try some internet searches for "geotextile(s)", "landfill liner(s)"...probably point you in the right direction.
