earthwall builds quality SIREWALL (Stabilized Insulated Rammed Earth) projects. We use the ultimate green material to construct structures for Spokane, Washington, Coeur d'Alene, Sandpoint, Bonners Ferry, Priest Lake, Lake Coeur d'Alene, Hayden Lake - anywhere in Eastern Washington or Northern Idaho.

SIREWALL walls - Stabilized, Insulated, Rammed Earth walls - present the ultimate green building material for eco friendly houses, green walls, and green wall technology that offers a uniquely compelling combination of desirable benefits for health, energy, eco-appropriateness, aesthetics and beauty, and durability.

For thousands of years, civilizations have been building with rammed earth. Secured wooden forms, filled with damp earth were compacted to create stable walls that have lasted several lifetimes.

SIREWALL® has updated ancient rammed earth processes with a new global standard for durable, healthy and energy efficient buildings and spaces. SIREWALLs are Stabilized, Insulated, Rammed Earth walls. SIREWALL homes and buildings are constructed with a matrix of local soils strengthened with rebar and a small percentage of cement that surround a core of insulation. A typical SIREWALL is 18 to 24 inches thick, with 4 inches of rigid insulation hidden in the center of the wall. From a dream home or cottage to a winery or cultural centre, SIREWALL builds beautiful walls with timeless distinction.

With tens of thousands of square feet of SIREWALLs built in the last fifteen years, the SIREWALL team has revolutionized a rammed earth system like no other. SIREWALLS are the only insulated rammed earth walls with a verifiable quality protocol that addresses the continuity of the thermal envelope, freeze/thaw cycles, vapour drive, insect resistance and optimizes the thermal flywheel, the humidity flywheel and all the elements affecting the final compressive strength. The SIREWALL team has more experience leading insulated rammed earth crews than all other related builders combined. SIREWALL’s library of CADD tools are created specifically for insulated rammed earth by the team’s expert designers.

The SIREWALL® system for quality control and soil blending builds walls that exceed current standards for energy efficiency and compressive strength. The SIREWALL System, along with customizable forms refined over the last sixteen years by SIREWALL’s expert builders, works seamlessly with unique designs and modern finishes that have timeless appeal.

SIREWALL has been the technological leader of insulated rammed earth development since its invention in 1992 and was the only practitioner for the first thirteen years. In fact, SIREWALL has a patent pending on the specific technology that leads the way in thermal and structural excellence in this emerging industry.

The SIREWALL system starts with secured reusable forms that are filled with a mixture of damp earth. The soil blend, once compacted, creates stable walls that will last several lifetimes without the need for maintenance. This approach has evolved over sixteen years of research & development to improve the technology and adapt the formula for different climates. The result: numerous award-winning SIREWALL homes and buildings and many satisfied clients.

Using SIREWALL’s system and ongoing advancements in technology, SIREWALL Project Managers always test soil before building, cure walls carefully, insulate with the most effective methods to ensure a continuous thermal envelope, use better retardants than those used in concrete, and tamp with mechanical tampers custom selected to optimize results.

The quality, beauty and durability of rammed earth walls are linked to the formwork used for construction. SIREWALL formwork has the flexibility of a modular system with interlocking end panels and versatile stretch panels. SIREWALL delivers predictable, cost-efficient results with minimal waste since the reusable formwork is easy to assemble and achieves consistent quality.

While most people are drawn to SIREWALL by its beauty, they may not realize that this inherent beauty is actually the result of our investment in R&D. To improve functionality, the strength of Stabilized Insulated Rammed Earth needs to be so much higher than its uninsulated cousin, so we continually refine our Standards to ensure superior strength and performance. Our Standards are the highest, and we ensure SIREWALL Project Managers, professionals who are the trained more than any other in the industry, meticulously follow them. Green Building enthusiasts inspired to break ground and build a rammed earth structure with the best of intentions may be missing key components to create healthy, energy efficient homes and buildings that will last for future generations.
