Drainage Gravel, Stone and Rock for Allen Texas
Material picks, pricing, and pro tips for drainage gravel projects in Allen, TX.
Drainage gravel in Allen and the North Texas metro
Allen sits at about 115,000 people in the Dallas-Fort Worth metro area, with steady growth bringing new construction and property improvements. Whether you are preparing a foundation, stabilizing a patio or managing water around a driveway, drainage gravel is essential. McKinney is only 3 miles away, Frisco 15 miles, and Plano just 10 miles out, so neighboring areas share the same soil and climate challenges.
Two main materials serve different purposes. #57 Crushed Stone provides a stable, compactable base for structures and driveways. River Rock works well where you want water to flow freely while keeping soil in place. Both are sold by the ton and work together in layered systems for optimal water management and stability.
Choosing the material and size
#57 Crushed Stone ranges from fines to roughly three-quarter-inch pieces. The angular edges lock together when compacted, making it excellent for foundational bases under patios, slabs and building footers. River Rock consists of smooth, rounded stones from three-quarter inch to two inches in diameter. Its rounded shape allows water to pass through easily without forcing water sideways.
Your choice depends on the job requirements. If compaction and structural stability matter most, go with #57 Crushed Stone. If free drainage is your primary goal, choose River Rock on top to filter water while resisting displacement.
Depth, base and how much to order
Depth varies by application. A foundation base typically needs 4 to 6 inches of compacted gravel. A drainage trench around a downspout might be 8 to 12 inches deep. To calculate cubic yards, multiply length in feet by width in feet by depth in inches, then divide by 324. This gives you a starting point for ordering.
Once you know the cubic yardage, you can use the calculator to convert to tons. A standard ton weighs 2,000 pounds and covers roughly 4 to 5 square feet at 6 inches deep, depending on the material density. At 15 tons or more, you qualify for free delivery and the lowest per-ton price.
Local conditions that affect the build
North Texas summers are hot and dry, then late spring and fall can bring heavy rains. The clay soils in and around Allen hold water, making proper drainage critical for any project. Drainage gravel moves water away from structures before it accumulates and causes settling or foundation damage. In new construction zones like Allen, contractors rely on drainage materials to protect concrete slabs and prevent frost heave in winter.
Delivery and getting started
Orders ship to delivery in Allen in 1 to 2 business days at smaller volumes, same or next day for orders over 8 tons. At 15 tons, delivery is free; under that threshold, a delivery fee applies to offset logistics. Most homeowners and small contractors call ahead, discuss their project size and timing, then place an order with confidence.

How a drainage gravel project goes
- Measure your project areaDetermine the length, width and depth in feet or inches. Sketch the area if it is irregular or complex. Drainage projects range from small downspout beds to large foundation perimeters. Accuracy here saves money and prevents ordering too much or too little material for your job.
- Calculate the volume and tonnageFor Allen projects, apply this formula: length in feet times width in feet times depth in inches, divided by 324 equals cubic yards. Then convert to tons. A drainage trench 20 feet long, 2 feet wide and 12 inches deep is about 1.2 cubic yards or roughly 1.5 to 2 tons depending on material.
- Choose your material and order#57 Crushed Stone locks together when compacted, ideal for bases and foundations. River Rock drains freely, perfect for filtering water in trench systems. Many projects layer both: crushed stone as the base layer, river rock on top. Decide based on your stability and drainage priorities.
- Schedule delivery to AllenCall with your tonnage and ZIP code to get a delivery quote. At 15 tons or more, you get free delivery in Allen. Orders below 15 tons incur a delivery fee. Orders under 8 tons normally take 1 to 2 business days. Orders 8 tons and up often arrive same or next day depending on the current schedule.
- Prepare site, place and grade materialClear debris from the area before the truck arrives. When delivery comes, direct the driver to place the material as close as possible to your project area. Spread and grade to the depth you calculated. Compact if needed for base layers. Water lightly to settle dust when done.

A planning figure, not a guarantee. Order roughly a tenth extra to cover settling and uneven ground.
Drainage gravel in Allen's climate
What works in Allen starts with how Texas weathers a year. Hot, dry summers and short mild winters. Drainage runs through dry topsoil quickly, so coarser stone holds shape better than fine grit. For drainage gravel work specifically, that means choosing material that handles local moisture and traffic loads without re-dressing every season.
The small market profile of Allen also shapes how a project runs. Most jobs are residential, with the occasional school or municipal project. Truck access is usually wide and turnarounds run fast.

What is #57 Crushed Stone used for?
#57 Crushed Stone is a compactable base material with particles ranging from fines to three-quarter-inch pieces. The angular shape locks together when tamped, making it ideal for foundation bases, patio underbeds, driveway bases and landscape edging. It resists settling and movement under load.
When do I use River Rock instead of crushed stone?
River Rock works best where water needs to drain freely without compaction. Use it in french drains, around downspouts, under planters and in filtration beds. The smooth, rounded shape lets water pass through but keeps soil from washing away into gravel layers.
How deep should drainage gravel be?
In Allen, the depth you need depends on your specific drainage project. Foundation bases typically use 4 to 6 inches of compacted material. French drains and downspout beds often go 8 to 12 inches deep. The deeper the gravel layer, the better the water dispersal and protection against settling.
How much drainage gravel do I need?
For Allen drainage trenches, measure length and width in feet, depth in inches for accuracy. Allen projects multiply length times width times depth in inches, then divide by 324 for cubic yards. Convert to tons using the online calculator. Most residential projects use 3 to 15 tons depending on area size and required depth.
Does Allen have free delivery?
Yes, for orders of 15 tons or more, delivery is free. Smaller orders incur a delivery fee based on distance and tonnage. Orders under 8 tons normally take 1 to 2 business days. Orders of 8 to 14 tons often ship same or next day depending on current demand.
What is the price per ton for drainage gravel?
Pricing depends on order size and material type. Smaller orders at 3 tons have a higher rate per ton. At 8 to 14 tons, the per-ton price drops. At 15 tons or more, you receive the bulk rate and free delivery. Call with your Allen, TX ZIP code for delivery and material pricing.
Is drainage gravel different from landscape gravel?
Yes, they serve different purposes. Drainage gravel is selected for water movement and structural stability in applications where it stays hidden. Landscape gravel is chosen for appearance and color. Never substitute landscape gravel for drainage work under foundations or in water management systems.
