Bulk Aggregates for Drainage in Downs, KS

Kansas Rock Supply brings gravel and aggregate delivery in Downs, KS, and drainage is the job that comes up first. Silty upland soil crusts over and sheds water, and the chalk and shale beneath it sits close to impervious.

So storm water has nowhere to go. Washed stone gives it a place: clean rock for French drains, drywells and downspout runs, and AB-3 for the drives and pads that need a base under them.

Materials for Downs Projects

Start with clean washed limestone. Water moves through it instead of pooling on top.

It is sold by inch size here, so you pick the size that fits the drain, not a blend.

For a French drain or a drywell, 1 Inch Clean is the standard open stone. It is also what pipe bedding and construction entrances call for.

#4 Crushed Stone handles heavier drainage and trench bottoms where a larger clean stone is wanted.

A downspout run or a tighter drainage bed takes a smaller stone. 3/4" Crushed Stone works for drainage beds and trench backfill, and 3/8" Crushed Stone covers fine drainage and pipe bedding.

For a general drainage product, Drain Rock is washed rock sold for French drains, dry wells and foundation drains.

Dense-graded material is the other half of the work. AB-3 is the Kansas name for dense-graded crushed limestone base, crushed rock and fines graded roughly 1 1/2 inch down, and it locks up tight when it is moisture-conditioned and rolled.

Driveways, parking pads, shed and shop bases and road shoulders all start there.

1 Inch Minus is the smaller cousin, for topping a drive, patching soft spots and building up shoulders. RipRap armours stream banks, pond banks, ditch lining, culvert outlets and slopes against flash runoff.

Ground and Conditions in Downs

Plan around the working season. This part of Kansas runs a long dry stretch either side of a short wet spring.

Rapid drying and dust are as much of a problem as rain when you are trying to compact material.

Across the Smoky Hills, Blue Hills and Post Rock country, the ground is silty and clayey over Cretaceous rock, with loess on many of the uplands. That is tight ground that does not absorb water quickly, which is why a clean stone drainage layer earns its place here.

Wind and water both work on exposed ground. Silt blows, and short intense storms gully bare slopes.

RipRap on a bank or a culvert outlet is doing real work, not decoration.

Winters are cold and dry with sharp temperature swings. Repeated freezing and thawing loosens compacted surfaces and heaves gravel drives.

Frost depth is set by each jurisdiction, so check the figure that applies where you are building.
