They are the professional-grade alternative to plywood or gravel. Below is a technical breakdown of what they are, their key specifications, and how to select between different types.

1. Core Specifications & Performance

While generic HDPE mats vary, the industry-standard style mats share these common characteristics:

Material: High-Density Polyethylene (HDPE), often virgin or 100% recycled, sometimes reinforced with fiberglass or UHMWPE for higher load ratings .

Standard Size: Typically 3m x 2.5m with a thickness of 38-105mm (approx. 4") .

Weight: Approximately 450-500kg per mat (solid core) . Note: This is significantly heavier than standard "yard" mats; lighter hollow versions are available for air transport/muskeg but have lower load ratings，

Load Capacity:

Solid Core : Supports vehicles up to 120 tons (cranes, excavators) .

Hollow Core (Composite): Supports up to 60 tons; withstands compressive loads up to 600 psi .
