How To Do Aggregate Concrete Patio

How to Create a Stunning Aggregate Concrete Patio

Create an exquisite outdoor living space by crafting an aggregate concrete patio. With its durable and aesthetic appeal, aggregate concrete will elevate any backyard or patio area. Here's a comprehensive guide to help you achieve a professional-looking aggregate concrete patio:

1. Planning and Preparation

Before embarking on this project, it's crucial to plan the layout of your patio, determine its size and shape, and prepare the site by removing any existing structures or vegetation. Proper drainage should also be considered to prevent water buildup.

2. Excavating and Forming

Excavate the area to a depth of at least 6 inches below the desired finished level. Compact the soil at the bottom of the excavation. Install form boards around the perimeter to create a frame for the concrete to be poured into.

3. Placing the Concrete Base

Pour a 4-inch layer of concrete into the forms and level it using a screed. This layer will serve as the base for the aggregate concrete.

4. Broadcasting and Troweling

Sprinkle the aggregate evenly over the wet concrete base, ensuring that it fully covers the surface. Trowel over the aggregate to embed it firmly into the concrete. Use a bull float to smoothen the surface and remove excess aggregate.

5. Finishing and Curing

Allow the concrete to cure for at least 24 hours before finishing. Once cured, use a grinder to grind off any unevenness and expose the aggregate. Seal the patio with a penetrating sealer to protect it from moisture and staining.

Additional Tips:

Use a variegated aggregate mix to create a visually interesting look.
Consider using a concrete overlay system for an existing patio.
Hire a professional for a more complex or larger-scale project.
Allow ample time for the concrete to cure before walking or placing furniture on it.
Regular maintenance, such as cleaning and sealing, will prolong the life of your aggregate concrete patio.
