What Tri-State Stone Co supplies

Stone yards carry flagstone, wall stone, boulders, river rock, cobbles and decorative gravel, usually sold by weight and frequently palletized for hardscape crews.

Thickness drives both coverage and price. Patio flagstone is typically 1"–1½"; anything thinner risks cracking underfoot without a mortar bed. Wall stone is sold by the ton with coverage depending on the face height you are building.

Full-line landscape supply yards stock soil, mulch, decorative stone, boulders, pavers, edging and often sod under one roof. That matters when a project needs several materials, because combining them into a single delivery avoids paying separate trip charges to multiple suppliers.

Because Tri-State Stone Co carries several material lines, it is often possible to combine an order across products — soil, mulch and stone on one truck — rather than paying separate delivery charges to two or three different yards.

How much material you need

Stone is sold by the ton. Natural stone runs roughly 150 lbs per cubic foot, so a single pallet can approach 1½ tons.

As a rough guide: 1 ton covers about 80–120 sq ft at 1½ in flag; 3 tons covers about 240–360 sq ft at 1½ in flag; 1 ton covers about 15–20 face ft at wall stone.

Measure your area and decide on depth before calling. Most yards will run the volume calculation for you and will flag when stepping up to a larger load actually lowers the price per unit.

Ordering and delivery

Confirm the delivery radius and fee early in the call. Two yards quoting similar material prices can land very differently once haulage is added.

Check where the truck can actually dump. Tandem trucks need overhead clearance and firm ground, and most drivers will not reverse across a soft lawn or a new driveway. If access is tight, ask whether they run a smaller truck or can leave the load at the kerb.

Pricing for bulk material is rarely published in full, since it moves with stock and season. The business website may list current products, but a phone call will get you a firm delivered number faster.

Review volume matters as much as the score. A 4.1 drawn from 57 reviews reflects a substantial track record.

Best time to buy in Maryland

Demand for stone peaks from spring through early summer across Maryland, when yards run their longest queues and hold firmest on price. Late summer and autumn typically bring shorter waits and more negotiating room, particularly on larger loads. If your project timing is flexible, buying outside the spring rush is the single easiest way to reduce the delivered cost.

Other suppliers nearby

There are 6 other suppliers we list within a short drive, the closest being The Junk Gorillas in Potomac, roughly 4.1 miles away. 29 suppliers sit within a 25-mile radius of this yard.

Because haulage is such a large share of delivered cost, the nearest yard carrying your material frequently wins on total price even at a higher per-unit rate.

Bulk material pricing is intensely local. Trucking is a large share of the delivered cost, which is why a nearby yard usually beats a cheaper one further out once the full quote lands.
