There are many different manufacturing and prefabrication processes involved in the creation of a SureClad® engineered stone ventilated façade panel.
Engineered stone is classed as a composite material but it is primarily made of natural stone, sourced from various quarries.
Large rocks are delivered from the quarries to the factory ready for sorting and processing.
The rocks are sorted and crushed into smaller more manageable-sized pieces and cleaned to remove impurities.
The smaller rock pieces are then ground to a very fine power aggregate and stored in large silos, ready for mixing.
The fine powder aggregrate is mixed with a minimum quantity of highly specialised bonding agent. The composite material is then fed into block moulds, compacted under vacuum and cured in ovens.
The blocks are stored in the open air where the curing process is completed.
Once fully cured, the large slabs can be cut into slabs of the required thickness. Because each slab is being cut from a solid block, it is possible to cut curved pieces as well as flat slabs.
At this stage each slab is processed further to deliver the required surface finish, which could be polished, honed or sand textured.
Before the finished engineered stone slabs leave the factory they are subjected to a final visual inspection.
