#Good Construction Practices – Terrazzo floors
Terrazzo is described as a composite material, poured in place or prefabricated for precast terrazzo which is used for flooring, base, walls, stair treads, countertops, and other custom products. Classic terrazzo is a mixture of marble fragments, called the aggregate, and a cementitious binding agent, called the matrix. It is resilient and can be used inside and outside, and it can be cast in place or laid in manufactured tiles. Terrazzo adds a luxurious component to both interior and exterior designs and can be used in truly innovative, sustainable ways , yet architects often don’t choose it because it can be expensive and difficult to detail. Dividers used in terrazzo floors must be located directly over concrete joints, which should occur a maximum of three times the depth of the concrete in inches. Concrete joints should also be detailed to run off all corridor intersections and corners and never be spaced more than 1.5 times the width of the concrete pour.
