US Patent 11913214 Bioretentional system and method of construction thereof

A bioretention system includes a number of connected wall portions defining an enclosure. Each wall portion includes a pair of spaced supports that support one or more panels that are interlocked with the pair of supports via mating interlocking features. Where a wall portion includes an upper panel atop of a lower panel, a lower edge of the upper panel and a top edge of the lower panel are in contact with each other to form the wall portion. The supports are then connected in spaced relation on the transverse axis by internal bars or beams which provide support for the wall portions without the need for external soil reinforcement.
