Concrete Surfaces

| Concrete Surfaces |

External surfaces can be divided into several groups:


- surfaces produced over freshly placed concrete;
- surfaces produced over hardened concrete;
- produced directly off the mould;
- surfaces suitable for painting;
- applied surfaces;
- graphic concrete;
- surfaces with complicated relief.

Surfaces produced over freshly placed concrete

Exposed-aggregate surfaces

Surfaces produced over hardened concrete
