PRE-CAST PERVIOUS CONCRETE

摘要

A pervious concrete slab is pre-cast in a reusable mold or form to define at least one keyway configured and arranged to engage with a complementary keyway of another similar pre-cast pervious concrete slab. The concrete slab is then cured in a controlled environment, transported to an installation site, and installed.
