When it comes to swimming pool deck you can consider a lot of materials that are available in the market. One of the option is exposed aggregate. If you’re looking to make your deck made of exposed aggregate, you should know the benefits and drawbacks of this material.
The exposed aggregate are consist of concrete material that contains decorative stones such as pebbles, granite, or quartz. These stones are exposed on the surface of the concrete, giving a unique and textured appearance to the deck. An exposed aggregate finish on your swimming pool deck can create a more natural, rustic look that complements the outdoor setting.
Pros & Cons:
Exposed aggregate concrete generates a natural textured effect by exposing the aggregate, or small stones, present in the concrete mix. Many pool owners choose this material for their pool decks as it offers several benefits.
Pros:
- Slip-resistant: Exposed aggregate concrete is an ideal material for poolside areas due to its natural slip-resistant texture, making it safe for wet use. The embedded aggregate stones add texture and grip to the surface, enhancing the material’s strength and durability.
- Durable: It holds up against heavy use and wear and tear, making it an ideal choice for poolside areas. It is also UV-resistant, ensuring that its color won’t fade over time.
- Customizable: It can be customized to match any home’s style, thanks to the variety of aggregate stones available in different colors and textures. The most common ones include:
- Gravel
- Crushed Stone
- Basalts Black
- Quartzite
- Crushed Glass
- Lifespan: When properly installed and maintained, exposed aggregate can last for 17 to 20 years without showing signs of wear and tear. This makes it a cost-effective option in the long run.
- Environmentally Friendly: Exposed aggregate is an eco-friendly option as it utilizes recycled materials such as crushed glass or demolished concrete. This reduces waste in landfills and helps conserve natural resources.
- Beauty and Aesthetics: Exposed aggregate offers a unique and aesthetically pleasing finish that can enhance the overall look of your outdoor space. With various colors, sizes, and textures to choose from, you can create a customized design that complements your landscape.
Cons:
- Higher Cost: The cost is typically higher if you select a more unique type of aggregate because of the additional labor involved in sourcing and installing it. This can make exposed aggregate a more expensive option compared to plain concrete.
- Requires More Maintenance: While exposed aggregate is known for its durability, it does require more maintenance than plain concrete. The surface needs to be sealed regularly to protect against staining and water damage. If the surface does get stained, it may require more frequent cleaning to keep its appearance.
- Not Ideal for High-Traffic Areas: Exposed aggregate may not be the best choice for high-traffic areas or heavy machinery because the rough surface can cause damage to tires or other equipment. It is better suited for pedestrian areas or light traffic.
- Potential for Uneven Surface: Depending on the skill of the contractor and the quality of materials used, there is a possibility that an exposed aggregate surface could end up with uneven areas or pockets where stones are more sparsely distributed. This can create an unbalanced and potentially hazardous surface, especially for those with mobility challenges.
- Discoloration: The stones used in exposed aggregate surfaces can be prone to staining and discoloration over time. This can occur due to exposure to elements such as dirt, oil, or chemicals. It is important to regularly clean and maintain exposed aggregate surfaces to prevent discoloration.
- Cracking: Like any concrete surface, exposed aggregate can also develop cracks over time. This can be caused by a variety of factors such as freeze-thaw cycles, heavy loads, or improper installation. To prevent cracking, it is crucial to properly prepare the base and use high-quality materials during installation.
| Pros | Cons |
|---|---|
| Slip-resistant surface (reduces slips when wet) | Rough texture (uncomfortable for bare feet) |
| Durable (withstands weather and heavy use) | Requires periodic sealing (every 2–3 years) |
| Customizable aesthetics (variety of colors/sizes) | Skilled installation needed (higher upfront cost) |
| Cooler surface (with light-colored aggregates) | Heat retention (dark aggregates get hot) |
| Low maintenance (vs. wood/pavers) | Repairs are challenging (hard to patch seamlessly) |
| Good drainage (minimizes puddles) | Traps debris/algae (needs frequent cleaning) |
| Cost-effective (mid-range pricing) | Sensitive to pool chemicals (chlorine/saltwater degrade sealant) |
| Long-term wear (risk of loose aggregates in freeze-thaw cycles) |
Remarks:
Exposed aggregate concrete can transform the look of any outdoor space, providing a unique and visually appealing finish. However, it’s important to be aware that this type of concrete is more susceptible to staining compared to traditional concrete. This is because the exposed aggregate surface has open pores that can easily absorb liquids and moisture.
When exposed aggregate surfaces are not properly sealed or maintained, they can easily become stained by substances such as oil, grease, food, and other common outdoor spills. These stains can be difficult to remove from the porous surface of the concrete without using specialized cleaning products and techniques.
