Abstract: Methods directed to a producing precast pervious concrete panels. Each pervious concrete panel has a plurality of layers of concrete mixture, wherein the aggregate used in each layer may be a different size and each layer is compacted after being laid. The method may further include providing a slip-former machine or an extruder machine to lay the layers of pervious concrete mixture.

Abstract: Systems and methods directed to a precast pervious concrete panel. Each pervious concrete panel has a plurality of layers of concrete mixture, wherein the aggregate used in each layer may be a different size. The panels have slots at predetermined locations allowing installation of a joint connector; either dry or with a bonding material thereby allowing connection of multiple panels into a solid slab. Multiple pervious concrete panels can be combined with a collection system allowing collection/reuse of water passing through the panels. Precast pervious concrete panels can be used as inserts in ready mix or cast in place concrete frames allowing for easy replacement of the pieces.

Abstract: A precast pervious concrete panel is formed in a containment vessel under controlled conditions and allowed to reach an acceptable strength before removal from the containment vessel, thereby producing standard sizes or shapes for installation in the field. Each piece of pervious concrete may include slots cut into the piece at predetermined locations allowing installation of a joint connector; either dry or with a bonding material thereby allowing connection of multiple pieces into a solid slab. A strip material may be used under the slab joints to dissipate load bearing and allow the panels to slide together when picked up by the embedded lifting device. Multiple pervious concrete pieces can be combined with a collection system allowing collection/reuse of water passing through the panels. Precast pervious concrete panels can be used as inserts in ready mix or cast in place concrete frames allowing for easy replacement of the pieces.
