Pervious concrete definition
Pervious concrete means a type of permeable pavement made with a rigid pavement similar to conventional concrete with the fine material reduced to form voids between the aggregate and allow water to infiltrate.
Pervious concrete means paving surfaces similar to conventional concrete except that
Pervious concrete means paving surfaces similar to conventional concrete except that the mixture omits the fines to create stable air pockets within the final product to allow water to drain to the base below, reducing stormwater runoff and allowing for groundwater recharge. Pervious concrete typically may have a rougher surface than conventional concrete.
Examples of Pervious concrete in a sentence
Special Equipment: Pervious concrete requires specific equipment for compaction and jointing.
Examples of retention systems include: • Man-made or natural depressional areas where the floor is graded as flat as possible and turf is established to promote infiltration and stabilize the basin slopes (see Figure 5.1-1); • Shallow landscaped areas designed to store stormwater; • Vegetated ▇▇▇▇▇▇ with swale blocks or raised inlets; and • Pervious concrete with continuous curb.
Pervious concrete and turf blocks are not considered impervious surface for this purpose.
