Exposed aggregate is a decorative concrete application that is achieved by laying concrete mixed with aggregate then stripping a thin layer off the surface to expose the aggregate beneath. This method creates a textured and multifaceted surface.Contact us
In addition to being beautiful, exposed aggregate has several benefits:
Its durability makes exposed aggregate a great surface for many locations:
An experienced contractor such as SUNDEK will have aggregate recommendations, but here are some factors to consider when thinking about what you want for your surface:
It can be exciting to explore the possibilities for aggregates, but keep in mind that there are some limitations. You’ll want to avoid flat or sliver shapes as they can easily dislodge from the surface. Stay away from anything that contains iron oxides, iron pyrites, or anything else that will stain concrete. An experienced contractor will be well informed on which aggregates to use and which to avoid.
The aggregate is combined with the concrete mix. After the concrete is poured and sets, a surface retarder is then applied to strip away the top layer and reveal the aggregate beneath.
We can also resurface existing concrete to look like exposed aggregate using our Aggregate Effects coating system.
An exposed aggregate surface can be customized according to your preference. Exposure ranges from light (where aggregate is slightly exposed) to full exposure (where aggregate is very visible).
Yes, just like any other decorative concrete surface, an exposed aggregate surface needs to be sealed to protect it from damage and prolong its lifespan. Learn the benefits of sealing your decorative concrete surface.
