Pervious concrete (PC), known for its high hydraulic capacity, is widely employed in paving and sidewalks, subject to environmental exposure such as rainfall and soil erosion. The hydraulic functionality of PC is intricately linked to clogging, influenced by material exposure and the potential for adjacent soil erosion. Sediments, transported as runoff, can partially or fully obstruct the material's pores, resulting in significant permeability reductions, often exceeding 90% of the initial permeability. Addressing this issue, hydraulic maintenance becomes crucial for PC, involving techniques to remove sediments and restore permeability. The choice of maintenance technique depends on the sediment type, a critical consideration in the mix design process. Implementing effective maintenance not only facilitates permeability recovery but also extends the material's hydraulic useful life. The maintenance periodicity will be project-specific, based on individual hydraulic requirements, ensuring the material's sustained hydraulic serviceability.
