Image
Right - Additional potential locations for slab-on-grade insulation include (a) under the slab and outside the perimeter with optional underground moisture block, (b) under the whole foundation, or (c) on top of the slab.
Image
Right - Basement slab with a capillary break of either gravel or a drainage mat.
Image
Right - Potential locations for slab-on-grade stem insulation in new construction: slab insulation should always be underneath, with stem walls insulated (a) inside, (b) outside, (c) not at all, or (d) outside with underground extension to repel moisture.
Image
Right - Retrofit of an existing basement slab by adding dimple plastic mat, rigid foam insulation, and a floating subfloor.
Image
Right - Rigid foam is installed over a waterproofing membrane that has been applied to the basement foundation walls.
Image
Right - The existing basement slab is retrofitted by installing a dimple plastic drainage mat, rigid foam insulation, and a floating subfloor.
Image
Image
Right - This rigid insulation is correctly installed in a level layer over aggregate; the seams will be taped
Image
Right - Workers installed rigid foam on the floor and the sill plates of these pre-cast, pre-insulated concrete wall panels to provide a continuous layer of insulation under and around the not-yet-poured basement floor slab.
Image
Image
Right – After installing the insulated concrete foundation wall panels, the builder installed underslab rigid foam, which was topped by 4 inches of crushed rock then the poured slab.
Image
Image
Image
Image
Right – Insulated concrete forms (ICFs) provide the insulated stem wall for the slab-on-grade foundation for this SIP house.
Image
Right – Polyethylene sheeting completely covers the aggregate and the footing with no tears or open seams
Image
Right – Polyethylene sheeting is laid over aggregate and over footing to provide a capillary break between the ground and the slab and between the footing and the stem wall
Image
Right – R-20 of XPS and polyiso rigid foam were added on the slab shelf that is part of this precast foundation wall system.
Image
Image
Right – Rigid foam was attached to the tops of the precast foundation walls to form an insulated edge for the floor slab.
Image
Image
Image
Image
Right – The drain slopes away from the foundation and terminates at the proper distance
Image
Image
Right – The foundation of this ICF home was constructed of ICFs that were set in place on a gravel bed, then 3.5 inches (R-36) of closed-cell spray foam was sprayed directly onto the gravel, providing an effective air, vapor, and thermal barrier.
Image
Right – The raised-slab, brick-and-block stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – The raised-slab, CMU block stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – The raised-slab, poured-concrete stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – The seam between the slab and the foundation wall is sealed with urethane caulk.
Image
Right – The slab is coated with two coats of epoxy paint to minimize moisture transfer through the slab from the ground.
Image
Right – This wall is constructed with the sill plate overhanging the top of the foundation wall so that when rigid foam is installed on the exterior of the foundation wall, its surface will align with the surface of the wall sheathing.
Image
Right – Workers lay radiant floor loops over the concrete reinforcement which is laid over a heavy vapor barrier installed over the sub-slab insulation before the slab is poured.
Image
Right – Workers pour the concrete for the basement floor slab over a vapor barrier installed over rigid foam.
Image
Right-Polyethylene sheeting is correctly installed over aggregate and taped to pillars and foundation wall
Image
Rigid foam extends under the full slab and lines the inside edges of the foundation walls.
Image
Rigid foam insulation and a thin slab were installed over the dirt and gravel of this sealed crawlspace
Image
Image
Rigid insulation and water control layers are installed on the exterior of a flat foundation wall; spray foam insulates the rim joist

Image
Spray foam extends down the foundation wall to the slab, which has been retrofitted by adding dimple plastic drainage mat and rigid foam insulation.
Image
Spray foam extends down the inside of the foundation wall to the uninsulated slab; because the wall lacked exterior perimeter drainage, the slab was cut and an interior footing drain was installed.
Image
Spray foam insulation extends down the foundation wall to the slab, which has been retrofitted by cutting the slab to install drainage mat against the wall and a new perimeter footing drain, along with rigid foam plastic above the slab.
