Understanding Exposed Aggregate in Concrete

What is Exposed Aggregate?

Exposed aggregate is a type of concrete finish where the top layer of cement paste is removed. This reveals the underlying aggregates like stones, pebbles, or shells. The result is a decorative and durable surface that is both functional and aesthetically pleasing.

This technique is popular for driveways, patios, and walkways. It offers a unique texture and look that can enhance the overall appearance of any outdoor space.
