EQUIPMENT ON
DEPLOYED GEOSYNTHETICS
* A dedicated piece of equipment can be
used only to deploy materials
Q: I'm hoping you can resolve a
disagreement among coworkers regarding
construction quality assurance (CQA).
I'm asking what is published and/or your
opinion. It involves traffic on geomembrane.
Is it now industry standard to allow skid
steers and/or ATVs to operate directly on a
geomembrane? It is assumed no turning,
spinning, etc. Technical specifications
typically state 5 psi (34 kPa) on 1 foot (30.5
cm) of soil on top of the geomembrane.
A: EPA/600/R-93/182-Section 3.3.4.1 " ...
using small pneumatic tire lifting units with
maximum tire inflation pressure of 40 kPa (6
psi). " This suggests ATVs (not skid steers) with
low ground contact pressure are acceptable.
That written, such equipment should be
accompanied with the following guidance:
* The equipment cannot transition on and
off deployed material (i.e., from soil to
deployed geomembrane)
* No sudden stops/starts
* No tire spinning
* Maximum tire pressure 6 psi (40 kPa)
* Only smooth and clean tires are acceptable
* 90° entrance and exits
* No excessive turning
* No driving over wrinkles
* One person per vehicle
* No vehicles on slopes
Please note that some state regulations
trump these recommendations. For instance,
Michigan does not allow any equipment on
deployed geosynthetics until 18 inches (45.7
cm) of cover soil is placed.
