Aggregate is a term that is used to describe a broad category of particulates used in construction and landscaping. Aggregate can be made up of crushed stone, gravel, sand, recycled concrete, slag, and other mined materials.
The use of aggregate is as broad as the materials that can be included in the aggregate family. One main use is to reinforce the strength of composite materials. Since the time of the Romans, aggregate has been used in various methods for construction projects, including all the Roman roads and aqueducts. In modern-day construction, aggregates can be found under foundations, roads, and railroads as well as around drainage applications.
Outside of the constructing of roads and buildings, aggregate has found a home in the world of landscaping. Many homeowners choose to use aggregate for their driveways because they can choose the color scheme of the aggregate, giving their driveway an updated look that is a nice alternative to a traditional concrete driveway. Aggregate changes color when it is wet, so it is wise to make sure that you know both the wet and dry look of the chosen material.
Another landscaping use is in the garden. Aggregate can be used to create walkways around your garden or even cover the bed of your garden. The rocks create a nice look with your plants and can help keep mulch in place so that your plants remain healthy. Aggregate also creates a nice contrast to any green areas in your yard. For those who want a low-maintenance yard, aggregate can also work as a modern alternative to a traditional lawn. Aggregate also works well in water features (rivers, waterfalls, ponds) that you might have in your yard.
Due to the wide variety of materials and colors, aggregate provides endless opportunities for your building or garden. Talk to a professional builder, landscaper, or material company to know which type of aggregate will work best for your project.
