Abstract:
1. A method of constructing an automotive vehicle parking lot on a land area, said method comprising the steps of: providing a composite drainage material through which water drains, the composite drainage material including a polymeric open mesh core between upper and lower layers of a non-woven geo-textile fabric; covering the land area with the composite drainage material by placing rolls of the composite drainage material adjacent one another, said step of covering the land area with the composite drainage material includes unrolling the rolls of the composite drainage material over the land area and positioning longitudinal edge portions of adjacent rolls in alignment with each other and with lower layers of non-woven geo-textile fabric engaging the land area, said step of positioning longitudinal edge portions of adjacent rolls in alignment with each other includes positioning a longitudinal edge portion of the open mesh core of a first roll of composite drainage material in an overlapping relationship with a longitudinal edge portion of the open mesh core of a second roll of composite drainage material, securing the longitudinal edge portions of adjacent rolls of composite drainage material to each other, said step of securing the longitudinal edge portions of adjacent rolls of composite drainage material includes heat fusing an upper layer of non-woven geo-textile fabric of one of the first and second rolls of composite drainage material to an upper layer of non-woven geo-textile fabric of another of the first and second rolls of composite drainage material while the open mesh core of the first roll of composite drainage material is in an overlapping relationship with the open mesh core of the second roll of composite drainage material to create a gapless and continuous surface of the composite drainage material with at least the majority of the land area lying underneath the composite drainage material, the lower layer of non-woven geo-textile fabric of each of the rolls contacting the land area, the upper layer of the non-woven geo-textile fabric of each of the rolls facing away from the land area and providing a gapless and continuous surface on which automotive vehicles are parked; and folding an edge portion of a first lower layer of non-woven geo-textile fabric back underneath itself so that the folded back edge portion of the first lower layer of non-woven geo-textile fabric is disposed between a portion of the first lower layer of non-woven geo-textile fabric and the land area; the composite drainage material conducting water through the upper layer of non-woven geo-textile fabric, through the core between the upper and lower layers, and through the lower layer of non-woven geo-textile fabric to the land area covered by the composite drainage material to drain water from the gapless and continuous surface on which automotive vehicles are parked.
