Self Supporting Paver System

Abstract

A paver support system includes an edging rail or bracket that engages an underlayment layer. The paver support system contains a plurality of paving elements within a prescribed area bordered by the edging rail and supported on the underlayment layer. The cooperating underlayment layer and edging rail are self-supporting to maintain the relative spatial relationship of the plurality of paving elements supported thereon.

         2 . The self supporting paving system of  claim 1  wherein the edging rail includes a first leg and a second leg, the first leg having a front tie that is severable such that the second leg is formable to accommodate a contour. 
     
     
         3 . The self supporting paving system of  claim 2  wherein the front tie includes at least one scribe configured to facilitate severing of the front tie. 
     
     
         4 . The self supporting paving system of  claim 2  wherein the front tie includes a frangible element. 
     
     
         5 . The self supporting paving system of  claim 1  wherein the edging rail includes a first leg and a second leg, the first leg having a plurality of barbs configured to pierce the underlayment layer such that the edging and the underlayment layer are fixed together. 
     
     
         6 . The self supporting paving system of  claim 5  wherein the plurality of barbs each include a flat face, the flat faces being oriented at a relative angle to each other such that the flat face resists movement of the underlayment layer relative to the first leg. 
     
     
         7 . The self supporting paving system of  claim 5  wherein the first leg includes at least one window formed therethrough, the at least one window being bounded by a front tie that is spaced opposite to the second leg, the front tie being configured to be readily severed such that the second leg is formable to accommodate a contour. 
     
     
         8 . The self supporting paving system of  claim 7  wherein the front tie includes at least one scribe configured to facilitate severing of the front tie. 
     
     
         9 . The self supporting paving system of  claim 8  wherein the at least one scribe is bounded by spaced apart chamfers. 
     
     
         10 . The self supporting paving system of  claim 8  wherein the at least one scribe is a pair of spaced apart scribes that define a frangible element. 
     
     
         11 . The self supporting paving system of  claim 5  wherein the first leg includes a plurality of windows that are each bounded by a front tie and the plurality of barbs are a plurality of primary and secondary barbs, the primary barbs being spaced between adjacent windows and the secondary barbs being provided on the front tie. 
     
     
         12 . The self supporting paving system of  claim 11  wherein each of the plurality of windows includes a back flange. 
     
     
         13 . The self supporting paving system of  claim 1  wherein the edging rail and the underlayment support the plurality of paving elements in a generally lateral and vertical direction relative to the support surface and the underlayment layer is configured to drain water away. 
     
     
         14 . The self supporting paving system of  claim 13  wherein the underlayment layer is formed from a closed cell foam material and includes a plurality of channels and drain holes adapted for water drainage. 
     
     
         15 . The self supporting paving system of  claim 13  wherein the underlayment layer includes interstitial voids that facilitate water drainage. 
     
     
         16 . A self supporting paving system comprising:
 a plurality of paving elements;   an underlayment layer configured to support the plurality of paving elements in a vertical direction relative to a subgrade layer; and   an edging rail configured to support the plurality of paving elements in a lateral direction relative to a subgrade layer, the edging rail being further configured to be fixed to the underlayment layer such that the edging rail and the underlayment layer are adapted to cooperate to support the plurality of paver elements atop of a support surface.   
     
     
         17 . The self supporting paving system of  claim 16  wherein the edging rail includes a first leg and a second leg, the first leg having a plurality of windows formed therethrough, the plurality of windows being bounded by a front tie that is spaced opposite to the second leg, the front tie including a frangible element configured to be severed such that the second leg is formable to accommodate a contour. 
     
     
         18 . The self supporting paving system of  claim 17  wherein the first leg includes a plurality of barbs formed between adjacent windows, the plurality of barbs each including a flat face, wherein at least two of the flat faces are oriented at a 45 degree relative angle to each other such that the flat faces resist movement of the underlayment layer relative to the first leg. 
     
     
         19 . A self supporting paving system comprising:
 a plurality of paving elements configured as perimeter paving elements and interior paving elements, the interior paving elements having a bedding material disposed therebetween;   an underlayment layer configured to support the plurality of paving elements in a vertical direction relative to a subgrade layer, the underlayment layer having a plurality of drainage channels and drain holes that cooperate to direct water away from the paving elements; and   an edging rail configured to support the plurality of paving elements in a lateral direction relative to a subgrade layer, the edging rail having a plurality of primary and secondary barbs that are configured to pierce the underlayment layer such that the edging rail and the underlayment layer are fixed together and to adapted to cooperate to fully support a plurality of paver elements atop of a support surface.   
     
     
         20 . The self supporting paving system of  claim 19  wherein the subgrade layer is one of a graded soil layer and a compacted sand layer.
