1. Face works - stones being cut and chipped to be place as walls of structures. Face works are used to define a massive appearance on some places of the structure. Most often in residences, face works are used in fire places, dens and those places intended to feel cozy and warm.
2. Paving stones - stones which are also cut and chipped, however, laid out on the pavement or foot paths. Paving stones are usually noticed in foyers or garages to bring out the massive appearance of the ground.
Rocks are also used in forming railways ballasts, or even blocks in abutments. In foundations or excavations, rocks are used as retaining walls and with its density, these walls need no or little amount of concrete.
Rocks are also crushed into smaller pieces to be part of the concrete. This is known as coarse aggregates or aggregates. Good coarse aggregates are limited in size and used most often in the concrete building structure from foundation, columns, beams to slabs and even roofs.

And yet the smaller pieces of rocks are converted as basic materials in fabricating other construction materials such as cement, hollow blocks, etc.
Artificial stones are those which are reconstructed. The common types of these stones are:
1. Terrazo - cement and marble chips combined
2. Mosaic tiles - pre-cast concrete tiles which are surfaced with marble chips
3. Cement concrete- reinforced cement concrete
