We Build as if Life Matters
Because it does.
SIREWALL is a complete wall system and has strengths comparable to high-strength concrete.
SIREWALL stands for Structural Insulated Rammed Earth.
The Three Technical Phases of Rammed Earth Construction
Rammed earth construction exists in three distinct technical phases: Traditional Rammed Earth (TRE), Stabilized Rammed Earth (SRE), and Structural Insulated Rammed Earth (SIRE). These technical phases are fundamentally different and are not interchangeable.
TRE, Traditional Rammed Earth
Ancient, unengineered construction using compacted earth. Relies on mass alone, with no insulation or defined strength standards. Generally unsuitable for modern regulated buildings.
SRE, Stabilized Rammed Earth
Often marketed as modern rammed earth. Uses cement, lime, or other binders to improve strength and cohesion, but remains mass-based and typically uninsulated. Commonly used as infill or veneer rather than a complete structural envelope.
SIRE, Structural Insulated Rammed Earth
An engineered technical phase of rammed earth construction that integrates structural rammed earth wythes with continuous insulation and reinforcement to form a complete building envelope. SIRE systems are engineered to meet or exceed compressive strengths of 20 MPa, approximately 3000 psi.
What Sets SIREWALL Apart
4 key things separate SIREWALL from other rammed earth providers. Not all rammed earth is alike.
Many other features make us the best rammed earth on the planet - check out SIREWALL features for more details.
3000+ psi
That means SIREWALL is a structural component of your building, high-seismic ready, freeze/thaw ready, doesn’t need to be sealed, and can be built below grade.
We won’t build anything less than 3000 psi.
In comparison, lower-strength rammed earth systems come in at 700 - 1000 psi.

Vapor Barrier
SIREWALL is a complete wall system that allows you use it in multiple ways and to eliminate multiple other traditional wall assembly trades.
A 600 micron finish
We can deliver smooth, high-end finished on our rammed earth walls that create exception finishes for living and working environments.
Other rammed earth tends to be rough and not pleasant to live with in close proximity.
Services to support you from planning, engineering, and permits, through to completing SIREWALL installations at the highest level.
Many of the projects you see on this site were designed and built by industry professionals working with SIREWALL for the first time.
More than 35 years experience in High-Performance Rammed Earth Projects
We help architects, engineers, contractors, and owner-builders execute extraordinary rammed earth projects with less risk and better outcomes. Through consulting, mix design, training, project support, Quality Control and Quality Assurance, SIREWALL helps teams move from vision to execution with greater clarity and confidence.
We help reduce costly mistakes, improve buildability, and support the strength, durability, and long-term performance that serious projects demand.
Extensive Experience in North America and Worldwide
SIREWALL has been in business for 35 years and we have been fortunate enough to have built on 5 continents, and many places around the United States.

SIREWALL is to Rammed Earth what a Tesla is to a horse and buggy.
(it is an analogy - we don’t necessarily endorse Tesla)
It’s the evolution of an ancient craft into a high-performance building system.
