One Crew for Roundup Concrete and Asphalt

Roundup sits where US-87 drops out of the Bull Mountains and crosses the Musselshell — the county seat of Musselshell County, coal and cattle country, about fifty miles straight north of Billings. Towns this size get skipped by the big paving outfits, which is exactly why we make the run: the highway from our Shepherd shop up through the Bulls to Roundup is one of the simplest drives in our whole service area.

The work up here leans asphalt — paving and repair for drives, lanes and lots, with crack sealing and seal coating to keep what you already own out of the replacement column. On the concrete side we pour and replace driveways, walks and steps built for a Musselshell winter.

Keep the asphalt you have

The cheapest pavement in Roundup is the pavement already on the ground — if it gets defended. Sun and hard freezes open hairline cracks, water gets in, and the base starts washing out from under the surface; one skipped maintenance cycle can cost more than a decade of upkeep. Crack sealing closes the doors water uses. A seal coat restores the surface and slows the sun. Together they are the difference between maintaining a lot and re-buying it.

When pavement is genuinely done — alligatored, rutted, potholing every spring — we say so and price the honest fix: cut out and rebuild the failed sections, or repave the surface entirely on a corrected base. What we will not do is sell a seal coat as a cure for a base problem. It is a sunscreen, not a skeleton.

Concrete for Musselshell County winters

Concrete work in Roundup runs the residential list — driveways, garage aprons, front walks, porch steps — plus patios for the backyards that look at the Bulls. Every pour gets the cold-country spec: air-entrained mix, compacted base, drainage-first grades and control joints, because a slab that holds water anywhere in this climate is a slab with a countdown running.

Old concrete that has heaved, settled or cracked through gets removed and replaced — we do not jack or level slabs, in Roundup or anywhere else. And with US-12 crossing US-87 in the middle of town, we cover the surrounding ranch and acreage properties in every direction while the crew is up this way.

Roundup FAQ

Questions From Roundup Property Owners

A few of the questions we hear most around Roundup. Don't see yours? Call us — we're happy to help.

Call (406) 717-4103

How often should a driveway or lot get seal coated?
The common rhythm is every few years, depending on sun exposure, traffic and how the surface was treated before. New asphalt should cure through at least its first year before the first coat. When we look at your pavement we will tell you where it is in that cycle — and if it does not need a coat yet, we will tell you that too.
Is Roundup actually in your service area?
Yes — the US-87 run from Shepherd, up through the Bull Mountains, is about as direct as out-of-town work gets for us. We batch Roundup and Musselshell County jobs together to keep the trips efficient. Call (406) 717-4103 and we will set up a free estimate.
Can a concrete driveway really hold up to winters here?
Built correctly, yes — cold-country concrete is a solved problem. The mix has to be air-entrained so freezing moisture has somewhere to push, the base has to be compacted and drained, the grade has to shed water, and the pour needs a proper cure. Winter does not defeat good concrete; it defeats shortcuts.
