Building with Faswall Natural Building Material. Step by Step

1. Design for Faswall

Design with Faswall In mind. Plan for block sizes in wall design, length and openings.

2. Level the Grade or build a Foundation

Faswall is excellent for Slab on Grade or Foundations in any type of soil or climate.

3. Stack the Concrete Form Blocks Without Mortar

The Faswall material wall forms (30lbs each, less than half a cement block) are simply stacked on top of each other without mortar. These are held in place by the interlocking tongue-and-groove end design, and walls can be built in any dimension/shape imaginable.

4. Set Rebar

Next, set rebar both horizontally and vertically within the stacked forms prior to filling the cores with concrete. This “post and beam” grid effect makes the concrete form material wall exceptionally strong.

5. Simple to Integrate & Install Windows & Doors

The preferred method is to fasten windows and doors directly into the wall form material. The End Blocks and Half Blocks are designed to build openings as they have smooth ends to which windows can be fastened with screws.

6. Install the Plumbing and Electric as you build

Plumbing & Electrical is readily Integrated

7. Fill the Faswall with Concrete

The Faswall concrete form material blocks are cast from a mixture of K-X Aggregate (mineralized wood chips) and Portland cement. The wall forms are designed as stay-in-place units, which become part of a load-bearing wall only after being filled with reinforced concrete.

8. Finish Cut and Nail Directly

Nail Directly

You can nail and screw directly into Faswall® concrete form material. You can also easily cut Faswall® blocks with carpenter’s tools.

Cuts Easily

Electrical wiring can be cut into the walls, or plumbing and electrical can be installed prior to pouring concrete.

Surface Finish on Both Sides

You can surface finish Faswall® concrete form material directly on both sides. It makes an excellent substrate for plasters and stuccos — it keys-in on the porous surfaces.


Faswall® Block Structure

The wall forms are supplied in three main types for building your entire project: a Standard Wall Form, a Corner Wall Form and an AP Wall Form.    More About Block Structure

Faswall Installation Guidelines

We did a lot of research on various green building systems but settled on Faswall. Not only did it seem like the “greenest” technology, but the ease of building compared to other systems seemed like a good choice for an owner/builder. What we didn’t expect, but were totally delighted with, was how knowledgable and helpful the people at Faswall were. We couldn’t have done it without you!
