During the past 15 or 20 years a type of terrazzo not previously considered practical or feasible has come into being. Florida and Texas, due to climate and rapid population growth, became the testing ground for this less expensive type of terrazzo which has been given the name monolithic due to the fact that large, solid areas could be installed without the use of divider strips to break the floor into small sections. Millions upon millions of square feet of this flooring have been installed in Florida and Texas and, more recently, in many other parts of the U. S. From a structural point of view there are three types of installation for terrazzo: (1) sand cushion strip terrazzo; (2) bonded to concrete strip terrazzo; and (3) monolithic terrazzo. Sand cushion strip terrazzo consists of a grout bed 3 inches deep with 5 /8 inch of terrazzo bonded to the surface. The entire grout bed, strips and terrazzo are one homogeneous mass which is separated from the underlying slab by a membrane and a bed of sand. A virtually level floor can readily be attained with strip-type terrazzo. Im bonded to concrete strip terrazzo, the grout bed is bonded firmly to the underlying concrete slab. The metal strip pattern should be planned so that a metal strip will coincide vertically with every joint. Monolithic terrazzo is bonded directly to the supporting concrete. Any cracks occurring in the concrete will always reflect through the terrazzo topping. However, in recent years much progress has been made in this field by anticipating in advance stress points and providing construction joints will later crack on through to provide a working joint.
