Porous Concrete Demonstration Project
In 2012, Redmond began looking for a porous concrete product that would give both good infiltration performance and good aesthetic quality. Redmond staff visited porous concrete installations throughout King and Pierce County. Various products were evaluated and a specification was ultimately selected.
Much to our surprise, the preferred product was right here in our backyard, provided by Cadman Concrete.
City crews ordered up a batch of the concrete, and under direction from National Ready Mixed Concrete Association (NRMCA), our crews were trained and certified in porous concrete installation.
The sidewalk was poured in November 2012. So far, this demonstration has been favorably received and the specifications used in this project are being used in the City’s Sidewalk Program.
