Less Weight, More Savings

TerraLam mats weigh less, so you can fit more with every truckload — saving up to 50% on freight costs.

TerraLam 300 (8’ x 14'): Fit 36 of these 14' new mats in each truckload (288 LF), compared to just 20 bolted access mats of the same size (160 LF).

TerraLam 504 (4’ x 16'): Fit 36 of these 16' new mats in each truckload (176 LF), compared to just 18 of the 4'x16' timber mats (72 LF).

TerraLam 508 (8’ x 16'): Fit 18 of these wider 16' new mats in each truckload (176 LF), compared to just 18 of the 4'x16' timber mats (72 LF).

TerraLam 700 (8’ x 16'): Fit 13 of these wider 16' new mats in each truckload (104 LF), compared to just 10 of the 4'x16' 12" crane mats (40 LF).

Faster Installation, Lower Costs

TerraLam mats are designed to be installed faster, which can save up to 40% on labor and equipment costs.

Engineered for Maximum Durability

Innovative cross-grain technology allows TerraLam mats to last longer, even with heavy tracked equipment.

For example, compare a TerraLam mat to a traditional lumber mat after an accelerated life test of 50 laps with a 44-ton bulldozer on a 22° angle.

Available Sizes

TerraLam cross laminated timber mats are available in 3- or 5-ply construction, with a variety of lengths and widths that fit your needs. Need a specific size? Just ask.

Frequently Asked Questions

Sterling 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.

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

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.
