When can I backfill the foundation wall?
The concrete must cure for a minimum of 7 days and the foundation wall must be laterally supported, meaning the floor system is installed supporting the top of the wall. All below grade waterproofing / dampproofing must be installed.
Can I install a 16' garage door and / or large openings in a concrete wall?
Yes, if the following criteria is available for the design of a concrete lintel (beam) over the opening – concrete lintel depth minimum 16″ (400 mm) or more with no point loads. Larger openings would require an engineered design.

Low Cost House Construction with Energy-Efficient Insulated Concrete Forms (ICF)

19 Important Features of an Energy Efficient Building
Is an ICF house faster to build?
The assembly and placement of concrete may take the same time as to build with conventional methods. The advantage with Fox Blocks is that the walls are now insulated, have a vapor and air barrier installed and are ready for finishes once the windows and roof are installed. These benefits will save weeks and/or months depending on the size of the projects.
