TL;DR
Exposed aggregate is a decorative concrete finish in which the top layer of cement paste is washed or retarded away before full cure, revealing the stones within the mix — or seeded pebbles broadcast onto the fresh surface — to create a textured, slip-resistant face. Popular for driveways, patios, and pool decks, the look depends on aggregate choice, from river pebble to crushed granite.
What it means
Exposed aggregate is a decorative concrete finish in which the top layer of cement paste is washed or retarded away before full cure, revealing the stones within the mix — or seeded pebbles broadcast onto the fresh surface — to create a textured, slip-resistant face. Popular for driveways, patios, and pool decks, the look depends on aggregate choice, from river pebble to crushed granite. The finish needs periodic clear sealing, since exposed stone edges pop loose where water and deicing salts attack the matrix.
