Clark County, WA Gravel and Landscape Rock Delivery
Looking for gravel, stone and aggregate delivery in Clark County, WA? Washington Rock Supply sells bulk material online and sends a dump truck to your site.
Start with 5/8 minus, the crushed surfacing top course that packs hard and sheds water.
Ground here is a mix of river terrace silt and gravel, weathered hill soils, and volcanic ash and lahar deposits. Soft, wet ground is the reason a base gets built before a surface goes on.
Ground Conditions Across Clark County
Clark County spans two ground regions. Around Vancouver, Camas, Battle Ground and Washougal you are on river terrace silt and gravel along the Columbia, plus weathered marine sandstone and siltstone.
Fine-grained terrace and hill soils hold water instead of shedding it. A pad or drive built straight on that ground moves and ruts.
Up around Amboy and Yacolt the ground changes. Soil is thinner and stonier over volcanic and granitic rock, with andesite, pumice and ash near the volcanoes.
That side drains faster but sits on slope, so runoff arrives quickly and scours shoulders, ditches and culvert outfalls. Erosion control matters more than base depth in places like that.
Winters are mild and wet with only shallow frost, so ground softens because it is full of water, not because it froze. Work is planned around the October to April wet season.
Materials Delivered in Clark County
5/8 minus is the Washington default surfacing course. It is crushed rock with the fines left in, so it compacts and sheds water rather than soaking it up.
Order it for driveways, parking pads, and shed or shop slabs.
The structural course under that is 1 1/4 minus, the crushed surfacing base course, or CSBC, with a 1 1/4 inch top size. It carries load and stays workable on soft wet ground.
Choosing the Right Material
Skamania County sits in the Columbia Gorge, on thin stony soil over volcanic and granitic rock. That ground drains faster than the terrace silt around Vancouver.
Where water moves through the ground quickly, a drainage layer matters less and slope protection matters more. Riprap and large round rock suit that.
Cowlitz County is in Southwest Washington and shares Clark County's ground regions, the Lower Columbia, Chehalis valley and Willapa Hills zone and the Cascade Range and east-slope valleys zone.
The ground is the same, so the material choice is the same. Minus products for a compacted base, washed products where water has to move.
