granite laying

[gsNagesh]

Dear all,

I saw some finished granite floorings, with edge burs, non uniform grouts with dust, though the granites were expensive and good ones. if laying is no good whats the point in getting expensive slabs.
Contraray to above have seen granite floorings with seamless joints or joints are not visible. How are these achieved? any contact for such layers in Bangalore? Kindly pm me contacts of such granite layers.
