What is Dowel
Laminated Timber?

DLT is a mass timber panel made by stacking softwood lumber and friction-fitting the boards together with hardwood dowels. No adhesives, no metal fasteners — just wood.

With all wood fiber oriented in the direction of the primary span, DLT offers greater structural efficiency than CLT for one-way spans. Panels can be precision-milled with CNC for service channels, acoustic profiles, and custom connections.

Six Reasons to Build
with Mad River DLT

A mass timber product that delivers on structural performance, sustainability, and constructability.

Structural Efficiency

Optimized for one-way spans with all fiber oriented in the load direction. Lighter than steel and concrete, reducing foundation requirements.

No Adhesives or VOCs

Free from structural adhesives and volatile organic compounds. Healthier indoor air quality through biophilic design with exposed wood surfaces.

Carbon Sequestration

Wood stores carbon for the life of the building while reducing reliance on carbon-intensive steel and concrete manufacturing.

Prefabricated Speed

A 5-person crew can erect over 2,000 sqft per day. Just-in-time deliveries minimize site staging and neighborhood impact.

2-Hour Fire Rating

Meets Type IV Heavy Timber requirements of the IBC. Tested assemblies achieve up to 2-hour Fire Resistance Rating with 2x6 DLT panels.

100% California Sourced

Full traceability from forest to finished panel. FSC-certified timber sourced from private, tribal, and public lands across Northern California.

Forest to Finished

Vertically Integrated
Supply Chain

As part of the Schmidbauer Group, MRMT controls every step from timber harvest to finished DLT panel delivery.

01

Sustainable Harvest

Timber sourced from forest health projects, tribal lands, and private timberlands across Northern California under rigorous forest practice rules.

02

Sawmill Processing

Logs processed at Schmidbauer Group sawmills, converting small-diameter timber into dimensional lumber graded for structural performance.

03

DLT Manufacturing

Lumber is stacked and joined with hardwood dowels in our facility in Korbel, CA. CNC-milled to project specifications with factory-applied sheathing.

04

Project Delivery

Flat-packed panels delivered just-in-time to the construction site, ready for rapid erection as prefabricated floor, roof, wall, and beam elements.

Built for California's
Climate Goals

Every MRMT panel supports forest health, reduces embodied carbon, and aligns with California's groundbreaking AB 2446 legislation.

CO2 Carbon Stored

Wood sequesters carbon for the entire lifespan of the building, offsetting emissions from construction.
