the outside of a home depending on your project or time of year for project completion.
Injection foam inside and outside
Injection foam can be completed both inside and outside using the same technique. Holes are drilled inbetween the studs from the base of the wall to the ceiling. Foam is injected into the lowest holes until the foam is done reacting and expanding. The foam will “puff”out the hole created at the lowest point first. Once it is done reacting foam is injected into the next level hole until the process is complete, and thus repeating the process until all levels of holes are filled. Once all the holes are filled, and the reaction is complete, the excess foam that has “puffed” out of the holes are cut off flush with the drywall (indoor)/outside wall with the siding removed (exterior). All cavities are checked for “voids” using a flir thermal imaging camera. Any voids will be filled by drilling a smaller hole and using a quick fill technique. this process is completed using 2lb, closed cell, slow-rise injection foam. All surfaces are thoroughly covered to protect indoor items from foam overspill.
An example of what it looks like when the wall cavities are completed and filled. “Puffs” are out meaning only drying time left and then they will be cut off flush with the wall and cleanup will commence.

Once the process is complete and the “puffs” have been scraped flush, the inside projects are ready for plaster and paint, the outside projects are ready for moisture barrier and siding.
Injection foam has an number of other applications, it can also be used to “Foam Jack” sunken concrete slabs and sidewalks. More to come on that in the near future. Check back often for new content on FOAM JACKING and other Injection Foam applications.
