Frequently Asked Questions: Aggregates at Connecticut Stone

What’s the difference between masonry and decorative aggregates?

Masonry aggregates are primarily functional—they’re used to create a stable foundation or underlayment for paver and stone installations. They can also be mixed into cement or used for leveling surfaces.

Decorative aggregates, on the other hand, serve both a functional and aesthetic purpose. While they still help with things like drainage and weed control, they’re also chosen for their beauty and visual appeal—enhancing curb appeal in gardens, driveways, or landscaped areas.

What size aggregate do I need?

The size of aggregate you need depends on your project:

3/4" to 1" crushed stone – Ideal for driveways, walkways, and drainage applications.
Pea gravel (3/8") – Best for decorative landscaping, garden paths, and playground surfaces.
Stone dust or sand – Used as a base material for pavers and patios.
Larger aggregates (1–2"+) – Suitable for erosion control, French drains, and foundation work.

Our team can help determine the best size for your specific project needs.

Do you deliver aggregates?

Yes, we offer delivery services for all our aggregate products. Delivery availability and pricing depend on location and order size. Please contact us for details.

Can I pick up aggregates at your location?

Yes, customers are welcome to pick up aggregates directly from our location. We recommend calling ahead to confirm availability and prepare for loading.

Are your aggregates environmentally friendly?

Many of our aggregates are sourced responsibly, and we offer options that promote sustainability, such as recycled stone products.

Do aggregates require maintenance?

Yes, periodic maintenance may be required. For example, gravel driveways may need occasional raking and replenishment to maintain their appearance and function.

Do aggregate colors vary between shipments?

Yes, natural aggregates can exhibit color variations due to differences in quarry batches and geological factors. We recommend requesting a photo of our current stock, visiting our showroom to view materials in person, or requesting a sample to ensure the aggregate meets your expectations.

Which aggregates are barefoot-friendly?

For areas where barefoot comfort is a priority, such as pool surrounds or garden paths, we recommend using smooth, rounded aggregates like pea gravel or river rock. These materials are gentler on feet compared to sharper, crushed stones.
