Askov sits in Zone I — Minnesota’s most severe frost designation. That means the ground freezes deep every winter and the spring thaw puts real stress on any driveway or access road that wasn’t built with the right material and the right base depth.
Pine County’s sandy glacial soils drain well, which helps. But sandy soil settles unevenly under load when the base isn’t prepared correctly — a driveway that looks fine in July develops ruts, soft spots, and heaving by April if the aggregate selection and base depth didn’t account for what northern Minnesota winters actually do to the ground underneath.
This isn’t a problem you solve by dumping more gravel on top. It starts with the right material — Class 5 gravel that packs into a durable surface, crusher run for a stable base — delivered in the right quantity to the right depth for your specific site.
Rural residential properties and cabin access roads along MN-23 and the I-35 corridor deal with this every spring. So do lake and cabin properties throughout Partridge Township near Banning State Park.
Tollefson Excavating has delivered and installed gravel driveways in Pine County for over 12 years. We know what holds up here.

We had some driveway work done and are so happy with the result! Connor returned calls quickly, came out and got us a quote and did the work as soon as road restrictions lifted!! We were out of town when he did the work and he sent us pictures of the progress! He even fixed a walkway issue without adding any cost! Highly recommend Tollefson excavating!

We had Conner come out to our property to help us complete our hay field restoration project. Conner went above and beyond what was expected. We appreciated his clear communication and vision for what we needed done. We will be using Conner for our future projects and would highly recommend him.Posted on Google![]()

I hired Tollefson to excavate my garage site (on a hill in Duluth) and remove three tree stumps from site. He did a great job, was easy to communicate with, came out an extra time and fixed an error made when marking site (not his error - contractor error), and made sure my back-fill happened before freeze up! He even seeded and put straw over when he was done.Posted on Google![]()

We hired Tollefson Excavating to dig out our existing pond, which had become overgrown and was turning into an eyesore. Conner completely revitalized it, and the results far exceeded our expectations! The pond looks so much cleaner now, and our family is excited to be able to use it. His skill with an excavator really showed, and he did quality work from start to finish. Overall, we had a great experience working with Conner and would highly recommend Tollefson Excavating to anyone looking for dirt work at a fair price.Posted on Google![]()

My wife and I felt comfortable right away after meeting Conner at our new home construction site. Not only did he do a fantastic job with site clearing, excavating and grading our new home site, Conner was there at our site the day he said he would be there. That was huge. I will highly recommend Conner to anyone looking for a reliable excavator.
From residential projects to commercial developments, we provide end-to-end solutions for every stage of construction.
We assess the site before material is ordered — driveway length, existing base condition, soil type, slope, and drainage pattern all determine what aggregate is needed and how much. Getting the quantity wrong means a second delivery or a surface that’s too thin to hold up through freeze-thaw cycles.
Material selection matches the application. Class 5 gravel for driveway surface — it contains a mix of rock and fines that pack into a hard, durable finish that resists shifting under traffic. Crusher run or road base for base layer where the existing sub-base needs reinforcement before surface material goes down.
Delivery reaches rural and cabin properties on Pine County’s back roads — not just sites with easy highway access. If your driveway is off the main route near Askov, we’ve delivered there before.
After delivery, gravel is spread and compacted evenly. Crowning — a slight center rise that sheds water to both sides — is the single detail that prevents water from sitting on the surface, freezing, and heaving the driveway from below every spring.
Built for Pine County. Delivered right. Graded to last.
A Pine County homeowner off the MN-23 corridor needed a full gravel resurfacing on a long rural driveway that had rutted and developed soft spots after several Minnesota winters on an inadequate base. We assessed the existing surface, delivered Class 5 gravel to the correct depth, spread and compacted evenly, and crowned the finished surface for drainage. No soft spots or rutting through the following spring thaw.
A cabin owner near Banning State Park in Partridge Township needed gravel delivered and graded on a seasonal access road that washed out during spring snowmelt every year. We evaluated the drainage pattern, delivered appropriate aggregate, built proper crowning into the finished surface, and addressed a low spot that was holding water. Road held through the following spring without washout or soft spots developing.

Class 5 gravel for the surface — it packs hard and resists shifting. Crusher run for base reinforcement where needed. We recommend the right combination for your specific site conditions.
Yes. We deliver to rural residential properties and cabin access roads throughout Pine County — not just sites with easy highway access. If it’s in the Askov area, we can reach it.
Full service — delivery, spreading, compaction, and crowning. Crowning sheds water off the surface so it doesn’t freeze and heave the driveway from below every Minnesota spring.
Every 1 to 2 years in Zone I frost conditions — or when you notice washouts, soft spots, or rutting forming. Regular maintenance prevents sub-base damage that costs more to fix later.
Yes. We deliver aggregate for building pads, equipment storage areas, private road maintenance, and general site work throughout the Askov and Pine County area.
