Super-Insulated Foundation

Dimpled vapor barrier material allows drainage along foundation walls, keeping the concrete dry.

The barrier product seals out water and bridges cracks.

Having the interior slab and foundation walls fully insulated and drained was an important part of this high-performance home.

An under-slab vapor barrier is essential for maintaining a dry concrete floor. The dimpling also contributes to radon isolation and venting.

The vapor barrier was placed atop the gravel base material with the slab then placed in direct contact.
