Rehabilitation of Permeable Breakwaters and Jetties by Void Sealing: Summary Report. Repair, Evaluation, Maintenance, and Rehabilitation Research Program
Many breakwaters and jetties have become permeable to sand transport and wave transmission, a condition that results in increased operations and maintenance dredging costs and increased risks and delays to navigation. First-cost savings could be realized by applying grouting techniques and sealing procedures developed for closing voids and fractures, instead of the more expensive method of applying layers of chinking and armor stone to the existing structure. The longevity of such grouts and sealants placed in voids of rubble-mound structures exposed to wave and current conditions is not well known. The term 'sealant' is used here to describe any material that closes voids and include grouts and very stiff, aggregate-containing cementitious and asphalt materials. This problem was separated into two parts; an evaluation of the effectiveness of materials already being used the development of guidance on sealant hole drilling, quantities to inject, techniques of injection, and knowledge of material properties to effectively create the barrier.
