Abstract
Non-abrasive pads are attached to the at least one side of concrete elements with nylon rivets that are embedded into the concrete when the latter is soft. A flexible rope is laced through the center of each element in two directions to form a mat in a row-column array. Adequate spacing is provided between each element to allow the mat to conform to an uneven seabed and cover the underwater installation. The non-abrasive pads separate the concrete elements from the underwater installation to prevent the concrete elements from scratching and ablating the delicate underwater installations. Grooves are provided in selected elements, and loops are provided at the outer edges of the mat to enable several mats to be linked together.
