A method of forming structures utilizing a hydrated lime material. A hydrated lime material is formed that is impermeable to water that is formed by subjecting a quicklime to a mixer and adding a surfactant and water to form the hydrated lime. The hydrated lime is then blended with a composite material to form a blended material that is impermeable to water. This blended material is then utilized in differing structures in order to form structures that are impermeable to water.
