In Situ Terrazzo
In situ terrazzo is a technique where a terrazzo mix composed of cement or resin and marble chips is poured and polished on site. Large areas can therefore be installed with this technique, and often with few or any joints, giving it a monolithic appearance.
Due to the nature of this Terrazzo technique, the design of the Terrazzo is always made bespoke. We have control over the background colour, the size and the colour of the chips, and further elements can be incorporated into a design such as chunks of marble or brass.
Before pouring the Terrazzo, the area to be laid is prepared to receive the mixture. With resin based terrazzo, a fibre glass membrane and a primer is laid down, and for cement based terrazzo usually a screed is required.
Following precise steps, the marble chips, pigments and cement or resin are mixed together before being poured onto the area to be laid. We use wood and metal dividers to create borders and patterns as you can see in the photos here. In Situ Terrazzo is a labour intensive process, and particularly when complex designs are sought.
Once laid, the mixture is rolled in order to eliminate air bubbles and condense the mixture. Marble chips are often then added on top by hand to complete the design.
The Terrazzo is then left to cure, usually only 24 hours for resin and up to 20 days for cement. Once dry the floor can then be grinded down and polished to reveal the terrazzo design.
The first step when designing a bespoke in situ terrazzo is to decide on a background colour. We usually work from a RAL reference and our technicians will match it by mixing different pigments. The next step is to choose marble chips to go into the terrazzo mix. Our technicians will advise you on the types of marble to use and their proportions to achieve a design. You can see below a selection of marble chips that we use to create bespoke designs, as well as a few semi precious and precious aggregates.
