For many years people have used foam substrates to create structures and then have coated them with concrete. Some have failed and some have been a disaster, however over the last several years, our industry has produced some real inovations in mix design.
Todays cementeous mixes have coated foam and actually created structural components with less than an 1/8" inch of material on both sides. This course is entirely focused on the development of foam and foam coatings to produce fast, structural substrates that are ready for carving in a short amount of time.
The premise is that there is no need to embed steel in your concrete to get the support you need. The primary materails used are various types of concrete, spider lath, fiberglass rebar, and fiber chop in concrete to cover foam to create a substrate that will not fail. If you do use steel, isolate it for its stregth but keep it out of an akaline environment.Read more
