ABSTRACT:
Disclosed is an apparatus for pipeline stabilization and shoreline erosion protection, termed a BulkMat device, for protecting and securing pipelines, which are typically located in ditches or on the floor of large bodies of water. In preferred form, the BulkMat comprises a long fabric mat with four to eight fabric compartments sewn onto the mat and filled with dry bulk sand/cement mix. In the preferred embodiment, the BulkMat is comprised of polypropylene. The BulkMat has four lifting loops that are used to pick-up and lower the BulkMat onto the desired location. When the bulk mat is placed on the location, and water sets in, the sand/cement mix in the compartments will harden to concrete. By hardening after it is set in place, the BulkMat will conform completely to the pipeline or covered area to be protected, precisely matching the specific area.
