Who We Are

Building on a Legacy
of California Timber

Building on the Schmidbauer Group's legacy in California's timber industry, Mad River Mass Timber (MRMT) represents the first vertically integrated mass timber manufacturer in California.

With a vertically integrated supply chain and deep regional expertise, MRMT delivers efficient, reliable, and customized mass timber solutions. Whether supplying raw DLT billets or fully prefabricated timber packages, we look forward to working with you on your next mass timber project — creating a story that flows back to your local forest and community.

Locally sourced timber is shaping a more sustainable, resilient future. After an extensive R&D effort, we have found Dowel Laminated Timber (DLT) to be the mass timber product that best meets the criteria for California's specific environmental and economic challenges.

The All-Wood Alternative

What is Dowel
Laminated Timber?

Dowel Laminated Timber (DLT) is a mass timber product made entirely of wood, using hardwood dowels to fasten layers of dimensional lumber together — eliminating the need for adhesives or metal fasteners.

This all-wood construction enhances sustainability, improves indoor air quality, and allows utilization of a greater variety of wood species and grades than adhesive-bonded products, supporting diverse forest management outcomes.

MRMT's products meet the criteria for materials derived from forest stewardship that enrich the land for future generations, utilize wood fiber practically and efficiently, meet future market demands for low-carbon construction, and promote the health and well-being of end users.

Where Our Wood Comes From

Full Traceability:
Forest to Finished Panel

At Mad River Mass Timber, we provide full traceability from forest to finished DLT panels through our vertical integration with Schmidbauer sawmills. Unlike many mass timber manufacturers that rely on third-party suppliers, our direct control over fiber sourcing guarantees supply chain stability, sustainability, and transparency.

We source timber from sustainably managed forests, including National Forests, Tribal lands, and forest health projects throughout Northern California, supporting wildfire mitigation and long-term forest stewardship.

This commitment ensures our products meet the highest standards for sustainable building certifications, carbon reporting, and responsible material sourcing.

Vertically Integrated

From Forest to
Finished Panel

As part of the Schmidbauer Group, MRMT controls every step from timber harvest to finished DLT panel delivery — providing our customers with unmatched supply chain reliability.

Sustainable Harvest

Timber sourced from forest health projects, Tribal lands, National Forests, and private timberlands across Northern California under rigorous forest practice rules. Supporting wildfire mitigation and long-term stewardship.

Sawmill Processing

Logs processed at Schmidbauer Group sawmills, converting small-diameter timber into dimensional lumber graded for structural performance. Exceptional processing efficiency with stable, reliable throughput.

DLT Manufacturing

Lumber stacked and joined with hardwood dowels at our facility in Korbel, CA. CNC-milled to project specifications with factory-applied sheathing for floors, roofs, walls, and beams.

Project Delivery

Flat-packed panels delivered just-in-time to your construction site. Whether supplying raw DLT billets or fully prefabricated mass timber packages, we partner with your team on the right solution.

California's Mass Timber Solution

Built for California's Forest
Health & Climate Goals

California's shift toward low-carbon construction will require materials that support wildfire resilience and sustainability. Mass timber, particularly Dowel Laminated Timber, offers superior fire and seismic performance while reducing reliance on steel and concrete.

This aligns with AB 2446, California's initiative to cut embodied carbon in construction by 40% by 2035 — ensuring a sustainable, low-impact future for the state's growth.

California faces a severe forest health crisis, with overgrown forests creating excessive fuel loads and contributing to catastrophic wildfires. Forest health is directly linked to the health of our watersheds. Active forest management — including thinning treatments — is necessary to restore ecological balance. MRMT's local timber sourcing aligns with the state's forest management goals by utilizing small-diameter timber from forest management activities across California.
