Gravel Delivery in Boulder, CO

Much of Boulder is built on swelling clay and bentonite-rich soil that expands when wet and shrinks as it dries, which can crack patios and push on basement walls. Around older homes in Mapleton Hill and Whittier, a perimeter trench filled with washed #57 stone carries snowmelt and spring storm water away from the foundation instead of letting it soak in along the wall. Homeowners in Table Mesa and Martin Acres use the same approach under downspouts and along side yards that stay muddy into April.

Gardening here means dealing with alkaline soil, a short growing season and strong sun at more than 5,300 feet. Working rich compost soil into vegetable beds and new xeriscape plantings loosens that clay and helps it hold water through dry summer weeks. For paths and small courtyards, #89 crushed stone packs into a neat, firm surface that sheds snow easily. Our #57 stone guide lists trench depths, and the compost guide shows how much to spread per bed. Flood-prone streets near Boulder Creek and the canyon mouth also benefit from stone-lined drainage swales, which slow runoff during heavy summer cloudbursts.

Front Range neighbors face the same soil and weather, so our Denver bulk stone and landscaping article is a useful companion, and the Fort Collins gravel delivery post covers yards much like those in north Boulder. For path and courtyard depths, see the #89 stone guide.
