Q: How does concrete float?

A: Each 10’x20’ concrete dock is approximately 23,000 lbs. With that weight, you’d naturally wonder… how does it float? Within the float, Type 1 EPS high-grade foam is placed and encapsulated by concrete. This is called positive flotation – and it offers greater stability and buoyancy than other types of flotation. Because of this technology, Surefloat’s docks are designed to be unsinkable.
