Problem with silt
this is very nice development in attempt of effective water management,But it is obvious that rain water carries large amount of silt with it which is uncontrllable and if this silt & clay passes through the pavement ther is threat of blockage of the pavement.. And this can pose a serious damage to the pavement. Also it is very difficult to re-establish the same. other ways should be found to overcome this problem. —Preceding unsigned comment added by210.212.192.18 (talk) as of 03:39, March 25, 2010 (UTC)


 * some balance issues with this article, specifically the EPA Storm water technology fact sheet, source #2 as of this post, lists several major drawbacks to porous concrete that are not mentioned in the article. 72.128.10.155 (talk) 00:46, 1 June 2011 (UTC)

Seems like the underlying soil would be washed away and then the concrete would have a dip in it after a while. — Preceding unsigned comment added by 162.157.42.210 (talk) 20:17, 14 May 2014 (UTC)

Distinction between Permeable Paving Systems and Porous Concrete
It seems as there is some confusion between Permeable paving and this Pervious concrete article. The distinction between the two is that Permeable paving is generally a system of pavers, concrete surfaces with large voids, polymer-based grass pavers, grids and geocells which allow for stormwater to infiltrate through the gaps or spaces between each paving technique. Pervious concrete allows for infiltration through the porous surface coating, as the surface is generally one cohesive area without gaps or spaces, which is listed in this article as only concrete, but permeable asphalt should also be included in this page as it performs a similar task to pervious concrete.
