Terrazzo Flooring

Another type of popular flooring is called terrazzo flooring or marble chips is, usually recommended for bathrooms and dining rooms flooring. With a special type of marble chips embedded in it, terrazzo is a concrete surface.

 

Terrazzo material is used for floor and wall treatments, a composite material either poured in place or precast. Poured with a cement binder for chemical binding, polymeric for physical binding, or a combination of both, consisting of chips of marble, quartz, granite, glass, or other appropriate material. In every pattern, the metal strips separate sections or changes in color or material. Before the Terraza sets, more chips may be sprinkled on the top of the mix. It is then pass through grounding and polishing to smooth or otherwise finished to produce a uniformly textured surface after it is cured.

 

Types and Systems

Both bonded and unbonded methods are used for terrazzo installation.

Bonded systems include the following:

  • bonded under bed
  • Monolithic
  • chemically bonded
  • thin set method (epoxy-resin)

While sitting on top of a concrete slab, the bonded terrazzo is applied over a sand-cement mortar under-bed. In the finished concrete slab that it sits on, the sand-cement layer allows for differences. An application directly over an extremely flat and high-quality concrete subfloor for the monolithic terrazzo. It does not require a concrete subfloor for thin-set terrazzo but instead, a flexible membrane can be installed. This is ideal so that cracks do not emerge on the surface.

For the unbonded method:

the sand cushion method Р which utilizes wire reinforcing, an isolation sheet, and sand dusting that soaks up any motion from the concrete slab.

Downturn of Terrazzo

The most familiar form of failing and is usually prompted by the structural system that holds up the terrazzo topping rather than the material itself is the occurrence of cracking. There is deterioration of the bonding agents used in terrazzo once exposed with alkalis or acids. It must first be cut out, after which the structural subsurface should be analyzed before trying to find a suitable replacement if a sizable portion of the flooring must be restored due to cracking. By having the matching colored marble chips as the remaining floor, the replacement terrazzo must attain a continuous look. The formula can be obtained for the common terrazzo. A “bracketing” system can be used otherwise, trying to create again the original formula by matching and mixing different chips.
