New directional signage was erected at the visitor’s parking entrance. Sign panels were made in concrete using siltcast technique devised by Arcosanti founder Paolo Soleri.

Styrofoam letter patterns were impressed onto the prepared silt bed. Planning intern Lily Ericsson is pushing an arrow pattern onto the silt.

Volunteer Daniel Wagner is carefully pouring slurry cement mix over the designs on silt.

Concrete mix and reinforcement steel are placed in the form.

After the concrete panel is dried enough to be lifted in few days, the silt attached to the concrete is washed away with water.

The raised letter surfaces are sanded and painted.

[We will report on how we erected the signage in place in the next posting.]
