Patent ID: 11162229

Abstract:
A paver system configured for installation on an existing hardscape. The paver system includes paving stones having a concave bottom surface. The concavity intersects edges of the paver to enable runoff to flow beneath and between the pavers. The concavity may also reduce the weight and material requirements of the paver while also increasing the strength of the paver. An underlayment is provided that includes a bottom surface with a plurality of intersecting channels. The underlayment is bonded to an existing hardscape, such as a concrete pad, and the pavers are arranged and bonded to the top surface of the underlayment. Rainwater and other runoff are allowed to flow between and under the pavers through the concave bottom portions thereof and through the channels in the underlayment. The paver system provides a strong, stable installation with sufficient drainage to resist damage caused by retained water.
