Subgrade and drainage are key

William Wright offers the following in response to the video from post (December 28, 2010):

“The two most important things that make a sod field serviceable are the quality of the sub-grade and the drainage.  My civil engineering company used a similar product for an area of vehicle parking we designed for Reliant Stadium in Houston, Texas.  If the Airfield in question has a good draining sub-grade this product should work well.  If however the subgrade is clay the field should be first crowned and graded to quickly remove rainwater before any type of reinforcing is added.  The type of reinforcing shown will be of marginal value if the field is rutted or has soft spots. Your money would be better spent stabilizing the subgrade.  Without more detail I can’t provide any more specific recommendations.”
