For decades, traditional hardwood timber mats have been the industry standard for temporary access roads, work platforms, and ground protection. Known for their durability and ability to support heavy loads, timber mats remain a trusted solution for many construction, utility, pipeline, and energy projects.
However, as project schedules tighten and transportation costs rise, contractors are looking for ways to improve efficiency without sacrificing performance. That's where TerraLam® CLT access mats come in.
Manufactured from sustainable Southern Pine using Cross Laminated Timber (CLT) technology, TerraLam® was engineered to provide many of the benefits of traditional timber mats while reducing the weight, variability, and logistical challenges often associated with hardwood matting.
So how do the two compare?
Traditional timber mats are typically constructed from dense hardwood species such as oak, hickory, and maple. Their weight and durability make them well suited for demanding applications including heavy lifting operations, deep drilling projects, and jobsites with standing water.
TerraLam® takes a different approach.
Rather than relying on the natural characteristics of individual hardwood timbers, TerraLam® utilizes Cross Laminated Timber (CLT) technology to create an engineered access mat with predictable performance and repeatable quality. The result is a mat that combines strength and durability with reduced weight and improved handling efficiency.
One of the biggest differences between TerraLam® and traditional timber mats is consistency.
Hardwood timber mats are built from natural lumber and assembled using metal rods, bolts, or fasteners to secure various individual timbers together. While manufacturers carefully select and grade materials, every board can possess different strength characteristics, moisture content, and grain patterns.
TerraLam®, by contrast, is manufactured using an engineered cross-laminated timber process that creates a repeatable product with known performance characteristics. Because the mat is engineered as an integrated structure rather than a collection of individual timbers held together with metal hardware, it delivers greater uniformity from mat to mat.
This provides:
For project owners and contractors, consistency often translates into fewer surprises in the field.
Transportation is one of the largest expenses associated with any matting program.
Traditional hardwood mats are extremely durable, but that durability comes with significant weight. Fewer mats can typically be loaded onto each truck, resulting in more shipments and higher
freight costs.
TerraLam® was designed to deliver strength while reducing overall weight.
Benefits include:
For projects spanning miles of right-of-way, these savings can become substantial.
Every material move impacts project productivity.
Because TerraLam® weighs less than traditional hardwood timber mats, crews can often move, stage, and install more footage with fewer equipment cycles.
This helps:
On fast-paced utility, transmission, and pipeline projects, time savings can quickly add up.
Many contractors assume heavier automatically means stronger.
In reality, engineered strength and predictable performance are often more important than raw weight.
TerraLam® mats are manufactured to precise specifications with known load capacities, providing a reliable foundation for project planning and execution.
Advantages include:
Contractors can make decisions with greater confidence when they understand exactly how their access platform is designed to perform.
Material handling costs are often overlooked when evaluating access mat solutions.
With traditional timber mats, crews may spend significant time loading, unloading, staging, and repositioning heavy materials.
TerraLam's lighter engineered construction helps crews:
The result is a more efficient operation from delivery through removal.
Project schedules depend on product availability.
Traditional timber mat production can be influenced by hardwood supply, labor availability, and manufacturing capacity.
TerraLam® is manufactured in automated facilities in the United States using sustainably harvested Southern Pine. High-volume production capabilities help ensure consistent supply for projects ranging from local utility upgrades to large-scale infrastructure developments.
For contractors facing aggressive schedules, reliable availability can be just as valuable as performance.
Environmental stewardship is becoming increasingly important across the construction and energy industries.
Traditional timber mats are typically manufactured from dense hardwood species that can require up to 80 years to reach maturity. TerraLam® mats, by contrast, are manufactured using Southern Yellow Pine, a renewable resource that reaches harvest maturity in approximately 20 to 35 years.
This faster regrowth cycle means forests can be replenished significantly more quickly, supporting up to 300% less deforestation impact when compared to traditional hardwood mat production.
Combined with advanced CLT manufacturing technology that maximizes fiber utilization and material efficiency, TerraLam offers a more sustainable approach to temporary access solutions.
Additional sustainability benefits include:
For organizations focused on ESG objectives, carbon reduction efforts, or responsible resource management, TerraLam provides a practical way to align project performance with environmental goals.
While TerraLam® offers significant advantages, traditional hardwood timber mats continue to play an important role across the industry.
Timber mats are often an excellent choice for:
The best solution depends on the specific requirements of the project, equipment, and site conditions.

Are TerraLam® mats stronger than timber mats?
Not necessarily. Traditional timber mats may be better suited for certain heavy crane and deep-water applications. TerraLam® is designed to provide engineered, predictable performance while reducing weight and improving logistics.
What is the difference between TerraLam® and timber mats?
TerraLam® is an engineered Cross Laminated Timber (CLT) mat manufactured from Southern Pine, while traditional timber mats are built from large hardwood timbers such as oak, hickory, and maple.
When should I use TerraLam® instead of timber mats?
TerraLam® is often preferred for utility, transmission, pipeline, renewable energy, and civil infrastructure projects where transportation efficiency, installation speed, and predictable performance are priorities.
Are timber mats still used today?
Yes. Timber mats remain a common solution for heavy lifting operations, drilling activities, crane work, and projects involving deep standing water.
Why are contractors switching from timber mats to TerraLam®?
Many contractors are making the switch because TerraLam® offers lower freight costs, easier handling, faster installation, engineered consistency, and reliable product availability.
