Manufacturing Process

Excellent Raw Materials

Our surfaces are composed of up to 93% quartz and are therefore designed to last

Materials Mixing

Raw materials are inspected, then fed into mixers and

blended together.

Pressing Materials as Slabs

The mixture is then poured into a mold and formed into a slab.  The slab is then compacted by a special vacuum and vibration process at a pressure of 100 tons.

Curing Slabs

The slabs are moved to the curing kiln and heated to 90 degrees C for 45 minutes which gives them the ultimate strength and solidity.

Polishing Slabs

Slabs are then gauged, calibrated and polished to a perfect finish in a wide range of colors and designs.

Quality Control

Quality control is paramount to Aggranite.  We select only the finest raw materials, which undergo and exacting series of production processes at our state-of-the-art manufacturing facilities.  Each and every one of our finished products is polished to perfection and ready to be rigorously examined before declaring it flawless and ready to be incorporated into your designs.


Aggranite was evaluated and certified by NSF international as a safe material for direct food contact.  This gives the assurance of maximum safety and protection to our customers and final consumers.


CE stands for Conformite Europeenne, the French phrase for European Conformity.  It is a standard that applies to a wide range of objects created and sold in the nation belonging to the European Union.  CE certification is designed to protect EU consumers by regulating products to reduce possible dangers to people and the environment.


The GREENGUARD Indoor Air Quality Certification Program identifies low-emitting materials, finishes and products for indoor environments.  Performance-based, field-validated standards are used to define products and materials with low chemical and particle emissions for indoor use.  Products are required to be tested annually for more than 10,000 individual volatile organic compounds (VOCs).

GREENGUARD Children & Schools

The GREENGUARD Children & Schools Certification Program was developed by evaluating chemical sensitivities of children along with unique building characteristics of schools.  It presents the most stringent product emissions criteria to date for low-emitting materials.
