How strong is pervious concrete compared to regular concrete?
Manufacturers claim that pervious concrete can be designed to have the same compressive strength as regular concrete. The pervious concrete for this site was designed with a compressive strength of 3,000 psi. Failure of our first pour was attributed to a strength below 1,000 psi. The second pour had a strength near 3,000 psi. It should be noted that the material became less pervious as the strength increased. For our site, compressive strength was not as important as the issue of porosity.
