Cohousing-L Mailing List: RE: Pervious Concrete Paving

[Michael Barrett (mbarrett]

A question for Prescott:
How does Pervious Concrete Paving perform when the water in those pores 
repeatedly freezes and thaws?  
Further it seems that the retention of (accidentally spilled dirty motor) oil 
in the pores of the material might be a possible disadvantage, making clean up 
even more difficult than solid concrete.
