Principle and structure of Terrazzo

  • Cementitious Terrazzo
  • Rustic Terrazzo
  • Epoxy Terrazzo

1. Cementitious Terrazzo

Sand Cushion Cementitious Terrazzo

This cement-based system is physically separated from the structural slab with an isolation membrane and a sand layer. The under-bed (sand layer) is reinforced with a wire mesh. Divider strips are best placed at a 5 by 5-foot distance. The overall thickness varies from 2.5 to 3″ including terrazzo topping.

Bonded Cementitious Terrazzo

In this method, the Underbed (sand, cement) acts as a bond between the concrete slab and terrazzo topping. Bonded terrazzo is 1 ¾” to 2 ¼” thick including ½” terrazzo topping. Divider strips are to be placed at fixed distances to avoid cracking.

Terrazzo topping (1/2” thickness) is directly bonded to the concrete structural slab without any under bed. This method is suitable where time and budget are the constraints. Divider strips are placed between them at regular intervals to separate colors or as a decorative feature.

2. Epoxy Terrazzo

Thin-set

Thickness varies between ¼” to 3/8” and dividers must be placed precisely where structural crack exists.

    Epoxy for Resin Terrazzo – A resin matrix is placed over the concrete slab. It is a lightweight flooring suitable for multipurpose use, provides resilience, and has the greatest tensile, compressive, and flexural strength.

   Polyacrylate for Cement Terrazzo – A polymer cement mix is placed on the concrete slab. It is well suited for use in areas subject to moisture vapor transmission.

3. Rustic Terrazzo

A textured surface that is non-grounded is used as a terrazzo topping. It has slip-resistant properties, useful for exterior works. Thickness ranges from 1/2” to 6”.

Terrazzo Tiles

Terrazzo tile flooring is similar to installing ceramic tile by using an adhesive and grout system.

Sustainable Considerations

These floors last for the life cycle of a building. Environmentally friendly products are also useful for resealing the floors. They are recyclable. A major part of the floor is constituted with naturally occurring materials/recycled content with zero VOC materials; therefore, it is a part of sustainable green construction.

Innovation in Terrazzo Floors:

Terrazzo tile floors are embedded with light-conducting channels to create a dynamic experience of light. The lights create a twinkling effect in the presence of light, movement, and shadows.
