Urbanisation increases impervious surface areas including car parking areas, roads, driveways, and rooftops. As a result of this are increased stormwater runoff volumes, which can result in increased soil erosion and stormwater pollution, and additional risk of downstream flooding. One potential solution that has been developed as a response to this challenge is Permeable Interlocking Concrete Pavers (PICPs). PICPs allow surface infiltration of stormwater into bedding layers and also trap pollutants in the aggregate matrix. Furthermore, stormwater volume entering drainage infrastructure is reduced as PICP systems store and gradually release water. As with all drainage infrastructure PICP systems require maintenance to ensure ongoing performance. PICPs are prone to clogging, which reduces their infiltration function and necessitates regular maintenance. It is hoped that investigating the factors that influence surface infiltration, new knowledge will be gained for the improvement of the infiltration function of PICP design.
