Drainage Gravel Solutions for Hillsboro, OR

Drainage gravel in Hillsboro for residential projects

Hillsboro, west of Portland, receives about 42 inches of annual rainfall concentrated in fall and winter months. That heavy precipitation makes site drainage critical. Any basement project, patio base, or driveway needs to shed water or risk damage. Homeowners and small contractors in the Hillsboro area understand the importance of getting drainage right.

The Portland-Vancouver-Hillsboro metro includes Vancouver in Washington, Gresham to the east, and areas extending south toward Salem. All share similar rainfall patterns. Installing drainage gravel correctly means your project will handle the region's wet climate for years.

Choosing the material and size

#57 Crushed Stone and River Rock are the choices for drainage work. In Hillsboro, both materials are sold by the ton. Crushed stone is angular, about half an inch, and compacts firmly to create a stable base. River rock is rounded and slightly larger, approximately three-quarters of an inch, and allows water to flow faster through the layer.

Use crushed stone under concrete, patios, or anywhere bearing load matters. River rock suits landscape work and applications where you want faster water movement and a more finished appearance. Layering them, stone first then rock on top, combines the benefits of each.

Depth, base and how much to order

Most applications call for 4 to 6 inches of gravel. Patio bases use 4 inches. Foundation drains run 6 inches. Find your tonnage by multiplying length in feet by width in feet by depth in inches, then dividing by 324 to get cubic yards. Use the calculator to convert cubic yards to tons and confirm what you need before placing your order.

When you order 15 tons or more, we provide delivery to Hillsboro at no charge. Smaller orders include a delivery charge in your quote.

Local conditions that affect the build

Hillsboro sits on volcanic soils that tend toward clay. Poor soil drainage is common. Installing gravel without sloping it to an outlet or connecting it to a drain pipe means water pools within the gravel and eventually fails. Every drainage layer must have a path for water to leave.

Compacting crushed stone in layers as you build prevents settling later. River rock is less affected by compaction but should be confined with edging or it spreads during foot traffic and rain events.

Delivery and getting started

Order delivery in Hillsboro and supply your address and site access details. A dump truck delivers material in one trip for orders up to 15 tons. Schedule placement 2 to 3 business days after you confirm your order.

Spread gravel evenly across your work area. Compact crushed stone firmly in sections if the area is large. Slope all material away from structures so water drains off rather than pooling against walls or foundations.

Drainage gravel in Hillsboro's climate

What works in Hillsboro starts with how Oregon weathers a year. 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 Hillsboro 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.
