Viaduct material

[peterpica]

Have an 18' graded viaduct that currently only has lath w/quick wall coating. I'd like to have a stone-like facade. Any suggestions? Any commercial materials available? Was thinking of covering with molded conrete sections (alum. foil, crinkling, concrete, etc.) & gluing, but am looking for easier alternatives, if any.

Thanks.

I seem to recall someone doing exactly that.  As I recal he used blue styrofoam and covering with mortar and stone.  If you spend the time to go through the old postings here I'm sure you will find his post with the problems he had during and after construction.  A couple of others have built the form work and then poured cement, then had problems with rusting rebar shattering the concrete from inside.

Use PVC or same good thick walled unstead of rebar. My 3¢.

Mine is made of cut foam for the shape, covered with chicken wire and stucco.  The wire holds the stucco and prevents it from cracking off the foam.  It's been in place for about 2 years now with no ill effects.  I would post a photo but I am on the road right now and don't have my photo library, but I assure you it's a great low cost technique that is about as fool proof as your can possibly get.

Here is a link to my rebuild thread from some time ago ;
