Abstract: A mat system includes a surface and at least first and second mat units. Each mat unit includes a respective plurality of blocks interlinked by respective cables that pass through the blocks. Each mat unit includes cable loops along at least one side section thereof. The first and second mat units are positioned on the surface in proximity to each other with cable loops of the first mat unit extending toward the second mat unit and cable loops of the second mat unit extending toward the first mat unit. A plurality of interconnecting blocks are positioned between the first mat unit and the second mat unit. Each interconnecting block includes an underside with downwardly open channels formed therein. The cable loops of the first and second mat units are positioned within the channels of the interconnecting blocks to cover the cable loops.

Abstract: A block and pad unit for use in forming a seabed mat includes a concrete block having an upper surface, a lower surface and at least four sides extending between the upper and lower surfaces. An opening extends from the upper surface to the lower surface of the block. An abrasive resistant pad is attached to one of the upper surface or the lower surface. The pad includes a base having a lower side adjacent the block and an upper side facing away from the block, an opening aligned with the opening of the block, and a plurality of dome-shaped mounds extending integrally upward from the upper side of the base and distributed about a periphery of the opening of the pad.
