This sustainable walkway uses 6 in. of pervious concrete over a 6-in. recycled aggregate base.

Screed rotates along forms to consolidate the concrete and smooth the surface.

Soybean oil emulsion is sprayed on the fresh pervious concrete surface as a curing agent. In this case, the emulsion is tinted to produce a decorative finish.

After the curing agent is applied, the surface is covered with plastic sheeting to retain moisture and enhance curing.

A hand roller is used to press the plastic firmly to the concrete.
