This construction site video of the Karuna House in Yamhill County, Oregon, demonstrates installation of a geofoam foundation that will superinsulate the bottom of the building envelope and help the project achieve Passive House and Minergie-P-ECO certifications.
Lead Carpenter Scott Gunter narrates the process of:
- screeding out gravel,
- back dragging with rake as needed,
- compacting gravel,
- marking outside foundation wall line on foam,
- setting and aligning geofoam, and
- drilling and pinning geofoam into place.
The Karuna House is designed by Holst Architecture and built by Hammer & Hand.
