Abstract: A protective mat for covering buried conduit in the form of a rectangular structure having upper and lower sections wherein the upper section includes elongated members, a sheet structure having a plurality of downward facing open cells, or an open grid or grating and wherein the lower section includes elongated members, a sheet structure having a plurality of upward facing cells, or an open grid or grating; a forward end that includes one or more protruding elements; and a rearward end that includes one or more recesses that are configured and dimension for receiving the protruding element(s) of a similarly configured adjacent mat. Thus, the protruding element(s) and recess(es) are associated with and located on the lower section of the mat such that the protruding element(s) of one mat can be inserted in the recess(es) of and adjacent mat to interlock the mats together.

Abstract: A mat having a non-wood core that provides strength and rigidity to the mat, and including a structure of a sheet, elongated members, a frame, compartments, or combinations thereof; and at least one outer layer associated with the core and made of elongated members typically made of wood or engineered wood. The core and outer layer(s) are integral or are joined together, and the structure of the core is made of one or more environmentally resistant materials to provide an extended service life when encountering rain, snow or other weather conditions that would eventually degrade wood. The mat has a load bearing capacity that is able to withstand a load of at least 500 to 800 psi or even 1000 psi without permanently deforming the core. Bumpers are preferably provided upon sides of the mat to protect them from damage due to transport or installation of the mat.
