Our Age-In-Place LEED home hit an exciting milestone: our first concrete-less slab base is installed! With the objective to reduce embodied carbon, instead of concrete, our “slab” floor uses 2 cross layers of Huber AdvanTech over insulation and vapor barrier. The 10 mil Stego barrier is placed between our 2 layers of Type IX EPS foam and taped off to the sill seal at the perimeter. All the seams and penetrations are well sealed. In the image above you can see the layer of fine gravel that went over the gravel base to provide a consistent, level surface. Sign up for a free mid-construction tour of this house on November 2nd.
