| As can be seen the greatest cost for this practice (regardless of configuration type) will be Material & Installation, which include costly components such as the, [[Liner|impermeable membrane/liner]], the [[underdrain]], the [[Permeable pavements#Foundation Aggregates|sub-base]] of 50mm [[clear stone]], base of 19mm [[clear stone]] and the [[Bedding layer|bedding pavers themselves]]. | | As can be seen, regardless of configuration type, Material & Installation expenses represent the largest portion of the total construction costs (82 to 85%).
