Bulk Aggregates for Patios in Underwood, MN

Minnesota Rock Supply brings gravel and aggregate delivery in Underwood, MN, and the working season here runs from the spring thaw into late autumn. Frozen ground stops compaction through the winter, so timing matters as much as the material.

Class 5 is the base course most of that work starts from, and it is the name to use when you order. From there, the right bedding decides how a patio or walkway holds up.

Ground and Conditions in Underwood

Underwood sits in Otter Tail County, in North central lakes, moraine and outwash country. The ground runs from sandy loam over gravel near the lakes to peat and muck in the low spots, with pockets of tight till between them.

Outwash sand takes water fast. The moraine till does not, and lake and wetland margins sit close under the water table, so meltwater has few places to go in spring.

That mix shows up under flatwork. A thin base over wet, uneven ground moves as the subgrade shifts, and a patio surface cracks along the joints.

Deep frost every winter makes it worse where a sandy surface sits over tight till or a high water table. Water trapped in that layer has nowhere to go as it freezes, and the ground lifts.

The fix is a base that spreads the load and a bedding layer that drains. Getting the layers right before the pavers go down is what keeps a flat surface flat.

Materials for Underwood Projects

Bedding under pavers and flatwork is the layer that levels the surface and moves water. It has to compact without holding moisture against the subgrade, and the material you choose sets how the finished patio behaves.

Granite Fines, also called screenings, are Crushed Stone from the St. Cloud belt.

They bed pavers, flagstone and patio stone, and they compact into a firm, level surface for a garden path.

Washed Sand, sold as concrete sand, is a clean bedding and levelling sand for slabs and pavers. It goes under the surface, not on top of it.

Below the bedding, Class 5 is the standard Minnesota base course. It is a compacted base for driveways, parking pads, shed and garage bases and road base.

Driveway Gravel, sold here as Class 2, is a 3/4 inch crushed aggregate with fines. It surfaces a drive or finishes over a compacted base, and Minnesota yards sell it as Class 2 granite, buff limestone or red limestone.

For drainage beside a patio, Drainage Rock is a 1 1/2 inch clear rock used in French drains, drywells, footing drains and downspout runs. Clear rock means washed, with the fines taken out.
