Build Homes
That Last.
Cornerstone Hempcrete crafts fire-resistant, mold-resistant, and termite-resistant homes using natural hempcrete — a timeless material for homes built to endure 50 years and beyond.
Why Natural Building
Designed for Health & Resilience
Hempcrete is nature's answer to modern building challenges. Every wall we pour is engineered to protect what matters most — your family, your investment, and your legacy.
Fire Resistant
Hempcrete is inherently fire resistant — it does not flame-spread and has a Class A fire rating. Its mineral-rich composition means your home stands strong even in Shasta County's wildfire-prone landscape.
Mold Resistant
The lime binder in hempcrete creates an alkaline environment that inhibits mold and mildew growth. Your family breathes cleaner air in a home that stays healthy for decades.
Termite Resistant
Unlike wood framing, hempcrete does not provide food or habitat for termites. Its mineral matrix is unappealing to insects, protecting your home's structural integrity without chemicals.
Superior Insulation
Hempcrete's thermal mass stores heat during the day and releases it at night, reducing energy costs year-round and making your home naturally comfortable in Northern California's climate.
Vapor Permeable
Your home breathes. Hempcrete's open structure allows moisture to move through walls naturally, preventing condensation buildup and maintaining healthy indoor humidity levels.
Carbon Negative
Hemp sequesters CO₂ as it grows, and continues absorbing carbon after it's built into your walls. Choosing hempcrete means your home is a net positive for the environment.
