Buidling with concrete allows for the flexibility of a modular system, while simultaneously providing the ruggedness, stability, and durability required in many locales. The mass of a concrete floating dock system, allows it to react gently to general wave action. There isn't any bounce, noisy rattle, or jarring motion. Since this is a rigid, monolithic system, there are no hinges to wear, loosen or break, utility connections aren't constantly flexing, and water and electric supply breakdowns aren't a continuing problem.In addition, concrete won't rot, corrode, or delaminate, is impervious to wood borers, and is unaffected by gasoline, solvents and other petroleum products. Concrete will withstand ice, sun, heat and high humidity, without causing deterioration to the module.
