Abstract

Planning for coastal protection structures requires a good of security and can be economical, so in the planning of structures for coastal protection needs to be well planned by making construction materials availability is good. Coastal protection buildings using Tetrapod, Dolos, X-Blocks are excellent buildings to be used for coastal protection in a region, but at the some areas natural resources are not available to make they are expensive, so a method is needed to reduce the the concrete by filling with material sand in the concrete without reducing the strength of the existing protective layer of concrete. Because the sandbag is made of bunny or plastic sack so it is often destroyed by sunlight, and sandbag damage is the beginning of the damaged construction, by it we wrap sandbag with concrete is a solution to combine armor layer with sandbag by maintaining tetrapod, dolos and X- Blocks will create interlocking between stones.
