Abstract: A multi-layer rig mat system and a method for implementing the rig mat system is provided. The rig mat system has a rig mat formed by interconnecting a plurality of panels in an edge-to-edge arrangement and one or more barrier layers placed between the rig mat and the terrain. The barrier layer prevents contamination of the terrain below the rig mat by water and other undesirable fluids seeping through gaps or discontinuities in the rig mat. The barrier layer also prevents heat transmission from the rig mat to the terrain below the rig mat.

Abstract: A connector apparatus includes first and second spaced apart generally coplanar walls and a support between the first and second walls. The first wall includes a first guiding surface and a first stopping surface extending at a first angle to the first guiding surface. The second wall includes a second guiding surface opposite at least a portion of the first guiding surface and generally facing towards the first guiding surface, a second stopping surface extending from the second guiding surface and away from the first guiding surface, and a third stopping surface extending at a second angle to the second stopping surface. The support has a fourth stopping surface, and the fourth stopping surface is disposed at third and fourth angles to the first and third stopping surfaces respectively.
