Why is the underside of my SILGRANIT II sink rough?

 

Each and every SILGRANIT sink’s underside does have some roughness and texture which may be interpreted as cracks.  This is a natural part of our patented formulation and production process.  The texture you are seeing on the backside is a result of the curing process of the material after casting.    It does not in any way deter from the strength of the product, but rather allows for the perfect combination of interior surface hardness and overall strength.  This ensures that the maximum amount of granite is at the useable surface.   It is this process that makes our sinks the MOST durable and the most hygienic surface available in the market today.
