This image shows the foundation of the Rowayton house. The foundation is constructed with a product called Superior Wall. Superior Wall is a a pre-manufactured insulated concrete wall system. It comes to the site in large panels shipped on trucks and lifted into place by crane. The panels are set on a gravel foundation and bolted together on site. The manner in which they lock together creates a weather and water tight bond which is then also water sealed along all of the outside underground surfaces. The benefit of something like superior walls is that they are pre-insulated (Similar to ICF’s*) and due to their T-shape they break a great deal of thermal bridging*.
