The Y2K truth is that that this construction solution provides the designer with true freedom of choice in terms of form, texture and appearance. Precast cladding panels in the form of reconstructed rock can look like any natural stone, but have lower absorbency, and consequently greater durability. Precast concrete cladding panels accommodate the reproduction of past styles and inspire the creation of imaginative buildings for the future. An almost limitless variety of finishes is available as concrete can be cast against patterned or textured formwork, its surface can be modified by tooling, or it can be faced wtih natural stone or ceramic tiles. There are five main categories for the range of finishes that can be produced on precast cladding.
