How does the ICF block get secured to the foundation?
The ICF blocks are held in place with either low expansion spray foam or a metal starter track. The bracing/alignment system, typically installed after the 4th course of block, also supports the ICFs in place. Once the concrete is in the wall there is no concern with the forms moving. The concrete is connected to the footing with reinforcing dowels.

What do termites do to the foam?
EPS provides no nutrient value and is not a food source for termites. If left exposed, termites may tunnel into the foam in search of fibrous food. When building, in a heavy termite infestation area, care is required in the detailing and construction of the walls that will be in contact with ground, to prevent access to the foam for termites.
Can you vibrate or consolidate the concrete in ICFs?
Yes, consolidation of the concrete is one of the key elements in the placement of concrete in an ICF wall. Fox Blocks recommends internal vibration with a pencil vibrator, quickly in and slowly out.
