Drainage gravel in Gresham for Portland metro projects
Gresham sits east of Portland in a region that receives 43 inches of rain annually. Most falls from autumn through spring. Water management around your home or construction site is essential. Foundation drains, patio bases, and gravel driveways all depend on material that lets water flow through without plugging. The Portland metro area includes Vancouver just across the border in Washington, adding to local construction activity and demand for reliable drainage gravel solutions.
Choosing the right gravel and installing it correctly prevents costly water damage and extends the life of your structures.
Choosing the material and size
The two primary options are #57 Crushed Stone and River Rock. The ton is the standard selling unit for both materials. Crushed stone is angular, roughly half an inch in diameter, and compacts into a firm base. River rock is rounded and larger, about three-quarters of an inch, and moves more freely as water passes through it.
For below-grade work and load-bearing bases, crushed stone is the standard choice. For landscape accents and areas where you want visual appeal alongside drainage, river rock on top for appearance and faster water flow.
Depth, base and how much to order
Standard depths are 4 to 6 inches depending on the application. Patio bases typically call for 4 inches. Foundation perimeter drains run 6 inches. Calculate volume by multiplying length in feet times width in feet times depth in inches, then divide by 324 for cubic yards. Convert to tons for ordering, or let the calculator handle the math for you.
Orders of 15 tons or more in Gresham receive free delivery. Smaller Gresham loads incur a separate delivery charge.
Local conditions that affect the build
The Gresham area has volcanic clay soils with poor natural drainage. Gravel alone does not solve saturated conditions. Slope your gravel bed toward a ditch, drain pipe, or daylight outlet so water has a path to exit. The Portland-area clay soils require this attention to detail or water sits in the gravel layer.
Frost heave is less of a concern in Gresham than in higher elevations, but compacting crushed stone firmly during installation reduces shifting. River rock placed for appearance should be confined or will move under foot traffic.
Delivery and getting started
We serve the Gresham area with delivery in Gresham. Confirm your exact address and access route. A standard dump truck carries up to 15 tons in one trip. Schedule placement 2 to 3 business days after your order is placed.
Spread material evenly by hand shovel or small blade. Tamp crushed stone in place, especially in high-traffic zones. Slope all materials away from structures to prevent water from pooling against walls.

Drainage gravel in Gresham's climate
Picking the right material for a drainage gravel project in Gresham comes down to how the climate treats it. Wet winters and dry summers. Stone with strong drainage prevents winter saturation under traffic. 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 Gresham 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 depth of gravel is needed under a concrete patio?
Four inches of compacted crushed stone is standard. Compact it firmly in layers before pouring concrete. Poor base preparation causes concrete to crack and settle, so take time getting this step right.
Is river rock suitable for a foundation drain in Gresham?
River rock works if you place it correctly. Larger aggregate allows faster water flow than crushed stone. Use it with a perforated drain pipe and landscape fabric to prevent soil migration into the gravel.
How does Gresham's clay soil affect drainage?
Clay sheds water poorly and can saturate quickly. Gravel alone does not fix poor-draining soil. You need slope to a discharge point, a drain pipe, or both. Without a water path, even good gravel material becomes overwhelmed.
Can I use drainage gravel for a vegetable garden base?
Yes, but only as a lowest layer. Gravel over-compacted crushed stone creates a root barrier. Top it with garden soil. Plants grow better in soil than in pure gravel.
How much material for a 30-by-40-foot driveway at 4 inches?
A 30x40 area at 4 inches deep is 148 cubic yards, roughly 222 tons. Start with crushed stone for compaction, then top with river rock if you prefer the appearance. Confirm exact tonnage with the calculator.
What equipment compacts crushed stone properly?
A vibrating plate compactor works best for areas over 500 square feet. Rent one for a few hours to prepare a driveway or patio base. Hand tamping works for small spots.
Will crushed stone wash into my gutters during heavy rain?
If your drainage material stays in a confined space (trench, retaining wall, or edging), it stays put. Unconfined material spreads over time, especially on slopes. Frame or edge your drainage work to keep it in place.
What is the typical lead time for delivery?
Most orders deliver in 2 to 3 business days. Confirm your address and access when ordering so the driver knows where to place the material. Have a clear drop point ready.
