The major difference between the two is the amount of water used. Russell III, executive director of the Cast Stone Institute is that “cast stone isn’t permitted to contain bug holes or air voids and must have a fine-grained texture, which is normally achieved by acid etching. This method calls for the construction of a reverse mold of the required unit. Cast Stone, on the other hand, solves both of these problems. In precast concrete con-struction, all the components of structures are produced in controlled environment and they are being transported to. Wet-cast pavers also have the ability to impersonate a variety of finishes such as wood, water and natural stone. 18) bars 50 (2) No. An increase in curing time means wet-cast pavers are more labor intensive to produce, resulting in a higher price point.
