Abstract

The NorthernSTAR Building America Partnership team implemented an innovative, minimally invasive foundation insulation upgrade technique on an existing home. The approach consisted of using hydrovac excavation technology combined with a liquid insulating foam. Two houses were originally selected for this field study. One was not ready for retrofit at the time of study and had to be eliminated. The collaborative nature of the one field installation, however, enabled the team to advance the methodology as the work progressed. Improvements to the method of installation and reduction of costs were developed on site. This is a repository for all "excavationless" foundation insulation retrofit projects performed by the NorthernSTAR research team. Minneapolis, MN 55411 - Test house for first NorthernSTAR excavationless foundation insulation retrofit.

Excavationless Exterior Foundation Insulation Field Study

Technical Report Schirber, T. ; Mosiman, G. ; Ojczyk, C.

Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. However, such an approach can be very costly and disruptive when applied to an existing home, requiring deep excavation around the entire house. The NorthernSTAR Building America Partnership team implemented an innovative, minimally invasive foundation insulation upgrade technique on an existing home.

Excavationless Exterior Foundation Insulation Exploratory Study

Technical Report Mosiman, Garrett ; Wagner, Rachel ; Schirber, Tom

Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. Controlling for bulk water, vapor, and wall temperature differential reduces the risk of rot and mold formation to insulation and building materials, thereby improving opportunities for structural integrity, indoor air quality, comfort, and energy efficiency. The intent of this study by the NorthernSTAR Building America Partnership team is to search for combinations of existingmore »« less
Excavationless Exterior Foundation Insulation Exploratory Study

Technical Report Mosimann, Garrett ; Wagner, Rachel ; Schirber, Tom

The key objective of this exploratory study was to investigate the feasibility of the development or adoption of technologies that would enable a large percentage of existing homes in cold climates to apply a combination 'excavationless' soil removal process with appropriate insulation and water management on the exterior of existing foundations at a low cost. Our approach was to explore existing excavation and material technologies and systems to discover whether potential successful combinations existed.
