Mad River Mass Timber (MRMT) is California’s first vertically integrated mass timber manufacturer, pioneering the production of Dowel Laminated Timber (DLT) panels for structural applications in floors, roofs, walls, and beams. Rooted in a five-generation legacy of wood products innovation, MRMT is based in Humboldt County and operates in partnership with the Schmidbauer Group of sawmills. This vertical integration ensures a transparent, efficient, and sustainable supply chain that supports forest health and wildfire mitigation efforts across Northern California.
MRMT’s DLT panels are crafted entirely from wood, using hardwood dowels to fasten layers of dimensional lumber without adhesives or metal fasteners. This all-wood construction enhances sustainability, improves indoor air quality, and enables the use of a broader range of wood species and grades. MRMT can serve as both a material supplier or a provider of complete mass timber building systems, offering flexible solutions tailored to project needs. With a commitment to innovation and environmental stewardship, the company is advancing high-performance, low-carbon construction throughout California and beyond.
