Bulk Aggregates for Patios in Mount Kisco, NY

Planning a patio, a driveway or a drainage run around Mount Kisco? New York Rock Supply handles gravel and aggregate delivery in Mount Kisco, NY, and most patio jobs here start with item 4 under the pavers. The ground you are building on decides how much of it you need.

Stony glacial till covers the hills, and ledge rock often sits close to the surface. Valley floors hold silt, clay and sand left by old glacial lakes, and that ground drains slowly after a storm.

Ground and Conditions in Mount Kisco

A thin base is the usual reason a patio or walkway goes wrong. The pavers settle, the joints open, and one corner drops after a wet spring. The surface stone was never the problem; what sat under it was.

Clay and silt on the valley floors drain slowly and stay wet after storms. Spring snowmelt and heavy rain push the Hudson and its tributaries up, so low ground can hold water for weeks. Frozen ground stops compaction in winter, and wet clay can stay soft into spring.

The fix is a compacted base built in lifts, with a drainage layer where water has nowhere to go. Cold winters bring repeated freezing and thawing, and the silt and clay soils on valley floors are especially prone to frost heave, so the base has to be built to take that movement. Frost depth is usually about 4 feet down for footings, and the local building department sets the exact depth.

Item 4 is the standard New York name for compacting subbase stone, and it is what goes under a patio, a parking pad or a shed base. It binds as it compacts, so it locks into a firm platform instead of shifting under the pavers. Order it by the ton and build the base in lifts.

Above the base, bedding is what sets your finished grade. Stone dust, also called screenings, is the usual New York bedding for pavers, flagstone and patio work, and it packs tight under a plate compactor. For a walkway or a joint line, Natural Pea Gravel, also called pea stone, gives you a surface that drains and stays walkable.

Where a patio meets a downspout or a French drain, washed stone keeps water moving. #2 stone, also called 3/4 inch crushed stone, handles drainage, septic beds and pipe bedding, and #57 stone covers French drains and concrete aggregate. Both are washed sizes that will not hold water the way clay does.

For the finish, river rock and large river rock build dry creek beds and borders that carry runoff away from the house. Screened topsoil and garden soil go back around the finished patio for lawn and beds.
