As a manufacture of this product, I can not agree more. We have just designed a Permeable Paver and am currently working on a design/installation manual. We suggest that the base material utilized be the clean/clear stone and the soils be left alone and NOT compacted because this will close the pores and not allow for water to "perk" as fast as possible. Here in Wisconsin we have a lot of clay. I have been looking for an outside company to test our product, but there does not seem to be one out there anywhere. It appears that what the ICPI suggests is what is specified on jobs. I have completed our own tests on these pavers and have great results. These are somewhat new for our area and everyone seems to gravitate to the internet when creating the specs. I like the concept, but am worried because there really can not be a generic installation for these since every job has different types of soils. I would like to see these treated like SRW's. Engineer/design plans for each jobsite due to the diffent types of soils. They require "perk" tests for each septic tank installed at a new home, why not the same for Permeable Pavers????
