Faswall for Basements and Foundations

Preparing for a Faswall block wall insulated slab

Vapor Permeable for No Basement Smell!

Many customers who want a living space below grade with no “basement smell” and excellent air quality are choosing to build their basement with Faswall®.

Faswall® regulates the relative humidity or moisture content of a room. The cement wood-fiber content of Faswall is vapor permeable and free-draining by nature, which means it eliminates moisture and mold problems.

Structure, High Insulation Value, and Ready to Finish Surface in ONE Applied Layer

  • Up to R 25.5 without any added insulation layer - High Thermal Mass for Energy Savings!
  • Installed cost comparable with poured wall or cmu insulated and finished to the same level.
  • Cuts with standard circular saws and reciprocating saws.
  • Builders crew installs, no need for special subs.
  • Qualifies for LEED points
  • Outside uses conventional waterproofing techniques
  • Inside can be direct plastered, drywalled, or simply painted for finished basements.
  • Vapor Permeability

Highly Insulating, Energy Saving, High Performance Built in.

Use Faswall for:

  • For stem walls,
  • Full foundations
  • Basement on Slab Construction
  • Below Grade Basement
  • Below Grade Living Space

Below Grade Surface Treatments of Faswall® Wallforms

Below grade wall surfaces outside of living space must be parge coated and waterproofed.

For some applications without living space inside, such as frost foundations, a parge coating is sufficient when used in conjunction with an adequate drainage system. Equally important to the effectiveness of any waterproofing system is adequate drainage. There are several products available to provide “in-plane” drainage throughout the full height of the basement wall. These, coupled with properly designed footing drains, will take the water away before it has the chance to become a problem.

Faswall is the best green solution for foundation work that is price competitive. What a powerful combination for the builder moving to sustainable building practices.

Why Use Faswall for Basements Instead of Conventionally-Poured Concrete

1. Vapor Permeability

Faswall ICF eliminates the damp/dank smell and feel of a traditional basement.

Wood fiber cement is vapor permeable and provides an air quality that is fresh, a temperature that is moderated, and a relative humidity that is constant. The indoor environment does not support fungal growth and spores.

2. Easy Interior Finishing Options

Faswall blocks create a finished wall surface in the inside which does not need to be firred out and insulated (unlike a poured concrete basement).

The Faswall ICF surface can be left as is and finish trimmed if desired, thereby creating an attractive surface (see this videoas an example).

Or, the surface can be plastered to directly, or dry-walled directly if desired.

Another beautiful option is to order Faswall block whereby the interior surface of the block is surface-trimmed to expose the wood fiber chips (see this video).

With conventional concrete, you have no other option other than to frame, insulate, and drywall it, which adds to the cost, time, and hassle of building.

And let’s not forget that do-it-yourselfers can stack Faswall block with ease in the initial construction process!

3. Environmentally-Friendly

One of Rich’s main concerns was building in an environmentally-friendly fashion. He was pleased to learn that Faswall block is one of the greenest building products on the market.

Not only would he get the solid foundation he needed, he would be doing good for the environment as well.

4. Competitive Pricing

A Faswal ICF-built basement will cost approximately the same as building a poured concrete wall basement, assuming that interior wall was to be finished (ie. firred out and insulated).

Faswall ICF is no more expensive than erecting and striping concrete forms, and then going through all the stages of stick framing against that concrete wall and insulating it to the level of insulation already available by building with the Faswall ICF.

Natural ICF Basement vs Poured concrete

When Rich Marshall, an environmentally-conscious homeowner in Seattle, moved a recycled home, he needed a basement foundation to set it on.

He initially thought he’d have to use conventionally-poured concrete for his foundation.

That is, until he discovered Faswall and was thrilled about the following benefits of a Faswall-block basement:  more
