Bulk Aggregates for Drainage in Colgate, WI

Start with the math, then pick the stone. Gravel and aggregate delivery in Colgate, WI runs on square footage, depth and tonnage, and Wisconsin Rock Supply can help you work out how much traffic bond, washed stone or sand a job actually needs. Colgate sits in Waukesha County, where slow-draining till holds spring rain and snowmelt near the surface.

That is why drainage work here leans on clean, washed stone rather than a base material that packs tight and sheds water slowly.

Materials for Colgate Projects

Drainage is the job that drives most jobs here: French drains, drywells and downspout runs. Those systems want washed stone with the fines screened out, so water moves through the voids instead of pooling in the pipe trench. Here are the sizes worth knowing, coarsest to finest.

RipRap handles the heavy end: lakeshore, stream bank, culvert outlets and slope armoring against spring runoff. #4 Crushed Stone sits under it for trench bottoms, construction entrances and heavy drainage.

Drain Rock is the standard for French drains, foundation drains, downspout runs and drainage behind walls. #57 Stone and #67 Stone do the same work at slightly smaller sizes and double as concrete aggregate.

For tighter spots, 3/8" Crushed Stone beds pipe and tops a compacted base, and #89 Crushed Stone fills joints and tight bedding. Screenings pack hard for paver bedding, while 3/4" Traffic Bond builds the driveway base that sits above all of it.

Ground and Conditions in Colgate

The working season runs from the end of the spring thaw into late fall. Frost leaves the ground earlier here than up north, but silty and clayey spots still heave and soften during the thaw, so compacted base laid on frozen ground will not hold. Plan the delivery for after the thaw and before the ground locks up.

Ground in this part of Wisconsin is lime-rich glacial till under a cap of silt loam loess, with sand and gravel in the outwash plains and moraine hills. Water collects in kettles, marshes and low ground between drumlins, and that slow-draining till holds spring rain near the surface. Frost depth runs at least 48 inches for footings under the Uniform Dwelling Code, and 48 to 72 inches under pavement by late winter.

On moraine hills, drumlins and graded sites, runoff washes silty soil off bare slopes and cuts into ditches and stream banks. RipRap on those slopes and clean stone in the drain trench are how you keep water moving instead of carving.
