Faswall History

After World War II, amidst the rubble and destruction, a way was discovered to take the huge volumes of wood waste, grind it into chips, mineralize the chips to neutralize the natural sugars that cause rot, and bond them to cement to form a building block. This is the genesis of the Faswall® ICF Wall Form.

Since then, tens of thousands of homes, commercial buildings, and many other projects have been built in North America, Europe, and Asia with this remarkable green building system. This remains one of the preferred methods of building in Europe. It has been available in North America for thirty years.

In 1987, Hans and Leni Walter of K-X Faswall International Corp. advanced the product with a patented mineralization process that allows virtually any wood or cellulose fiber to be bonded to cement.

In 2008, ShelterWorks Ltd. was assignedthe proprietary Faswall® wood chip-cement ICF technology and its trademarks in its entirety. ShelterWorks is the exclusive manufacturer of Faswall®.
