Permeable Pavers: Installer vs. Engineers
Due to our proximity to the Chesapeake Bay and it's tributaries, pavements reducing run off are becoming more and more prevalent. My problem lies with the specifications used by most engineers and architects.
Most applications are spec'd using a typical crushed aggregate base instead of a base utilizing various sized clean gravels. Instead of providing a system that allows water to perk vertically and naturally filter itself before discharge into the water table, the spec'd systems allow water to move below the paver but along the compacted base, often resulting in base saturation and movement. This, in my opinion, provides a false sense of environmental responsibility to both the designers and property owners. It seems that either they have done this to keep install costs down, or municipal requirements are sub-par.
It has occurred to me that designers and municipalities are just unaware of the differences between a typical install and a true permeable system, which leads me to ask... as installers, how can we change the views of these individuals and correct this problem? I would assume that this is where ICPI can assist, though from reading previous posts they don't have the support of many members here. Manufacturers should help shoulder the burden, but I have'nt gotten great response as yet.
What are your two cents?
