Shamrock Materials conducts a test pour of Ekocrete at its plant in Petaluma, Calif.

Licensees have exclusive distribution rights in their own regions, so Glessner and McCabe are targeting, “the most green-minded and progressive producers in each area.” They are making Ekocrete available nationwide with the goal of “turning all concrete green.”

Shamrock Materials in northern California is Ekocrete's first licensee. Its first delivery of Ekocrete will be for the driveway of a high-end residence in Sebastopol, Calif.
