FlotationFloatation is the foundation of any floating dock structure. ShoreMaster floatation has provided the foundation for all types of floating docks from the best marinas to the smallest residential floating dock systems. All of ShoreMaster’s floats are expanded polystyrene foam encased in a polyethylene shell so that they are resistant to the effects of sun and water and other pollutants such as oil and fuel, and will absorb little to no water if punctured. Give your floating dock system a solid foundation with floatation from ShoreMaster and you’ll have a structurally sound dock system for years to come.
