Save Time & Money With TerraLam^® CLT Mats

Mat strength lies in its ability to transfer weight through the mat into the surface below. Bolted mats only transfer load at the location of the mechanical fasteners. Adhered CLT mats transfer the load through every available square foot. Additionally, the adhesive provides a moisture barrier at each layer, protecting the mat from eventual rot and decay.

Bolted access mats and traditional timber mats are made with a variety of mixed hardwoods and softwoods, without consideration for lumber grade — resulting in inconsistency across mats. With an engineered cross laminated timber product, you can be assured that every mat delivered will perform to your specifications.

Currently TerraLam mats are available in 3- or 5-ply construction.

• TerraLam^® 300 CLT – 8′ wide x 14′ or 16′ long
• TerraLam^® 504 CLT – 4′ wide x 16′ or 18′ long
• TerraLam^® 508 CLT – 8′ wide x 16′ or 18′ long

Yes, in fact they are superior in promoting environmental stewardship. The adhesive becomes chemically inactive prior to leaving the Sterling facility, presenting no harm to the environment. (The metals in bolted mats oxidize, leaching contaminants into the ground and creating disposal difficulties.)

The raw materials in TerraLam mats are farmed in approximately 20 years, where the hardwood species used in bolted mats can take 80-100 years to regrow.

Additionally, the solid surface and adhesive barriers between layers don’t allow invasive species to embed themselves into the mats like with traditional mats.

TerraLam mats have been tested successfully in temperatures as low as -70°F and as high as 150°F. While all wooden mats can be slippery in wet, muddy, and icy conditions, the solid top of TerraLam mats makes removing mud, snow, or ice much easier. Once TerraLam mats are traveled on, they become well-seasoned, mitigating slickness in challenging conditions.

Since TerraLam mats are a solid block of wood, necessary repairs can be done easily and at less expense than with bolted access mats. Repairs to bolted mats often require removing rusted or bent bolts and fragmented boards. Damaged TerraLam mats are safer on the jobsite than a damaged bolted mat, as a damaged CLT mat does not expose crews to puncture injuries or equipment damage.

Sterling prides itself in creating long-term relationships, not maximizing transactions. A Sterling expert will review your project and work with you to determine whether it’s best for your business to rent, lease, or buy TerraLam mats.

TerraLam CLT mats are constructed with rapid-growth southern yellow pine #2 grade kiln-dried lumber, along with a moisture-activated polyurethane adhesive. The wood’s existing water helps cure the adhesive, creating an exceptional bond. Independent laboratories, including the USDA Forest Products Laboratory, San Diego State University, and Henkel Adhesives, have validated the strength and durability of TerraLam products.

The TerraLam Connect System allows you to tether adjacent mats together to maintain the integrity of access roads and platforms. This application is particularly useful in wetlands and areas that are experiencing heavy rain or flooding.

TerraLam mats can also be fitted with interconnecting fingers that work in the same manner as traditional bolted access mats.

The TerraLam Connect System is easy to use and can be completed by one person with an impact driver. Installation requires no pre-drilling. Simply lay the TerraLam Connect strap with each end on adjacent mats. Use an impact driver to install the screw through the hole on the bolt plate until it is tight against the mat. More detailed instructions can be found in the TerraLam Product Guide.

Prior to moving mats, the TerraLam Connect strap and lag screws must be removed. At the conclusion of a project, straps and screws should be collected and returned to Sterling with the TerraLam mats. The straps and screws will be inspected and re-used or recycled.
