Llano is granite country, which makes it the odd one out in Central Texas. The ground here is decomposed granite and surface stone rather than the limestone shelf you get east of the county line, and it behaves differently under a machine. We mill what will mill, tell you plainly what will not, and leave every bit of it on your place.
A rotating head with carbide teeth works the surface down in passes. Rock, caliche and the soil around them go through together and come back as a graded mix you can spread and compact. There is no digging out, no breaking into pieces somebody then has to move, and no truck involved.
Crushing is a processing trade. Rock goes into a crusher and comes out as sized aggregate to sell, spread or haul. Milling never separates the rock from the ground it came from. If what you need is base material delivered and spread, that is a different outfit and we will tell you so rather than take the job.
Grinding rock and soil together in place is exactly what stabilization means before anybody adds a chemical to it. The result is a blended, compactable subgrade instead of topsoil sitting on ledge. We do it mechanically with the head. We do not do lime or cement treatment, and if your engineer has specified either, you want a stabilization contractor rather than us.
This is the part people underestimate. No haul-off trucks down your road, no disposal, no gate torn up by loaded tandems, and no trips billed by the load. The rock you paid to have dealt with ends up as the surface you wanted in the first place.
A Llano lot that hits ledge is not a lost lot. Milling takes the high rock down and blends it into the base, so the slab crew gets a level surface that compacts instead of a change order and a week of delay.
Ranch roads through the granite country get milled to a surface that drains and holds. Decomposed granite mills well and packs hard, which is why it ends up as a driveway material in the first place.
Rock trails get milled wide enough to drive and smooth enough to want to. The milled fines bind rather than roll, so the trail holds through a wet spring instead of turning into a creek bed.
Surface rock is why a field will not take a drill or hold a stand. Milling the top rock in opens the ground so water and roots get down into it, which is the same reason we get called back for pasture reclamation after the clearing is done.
A milled, compacted surface sheds water in a direction you chose. A rock field sheds it wherever the rock decides. Milling lets us shape fall into a pad or a drive rather than fight water later with rock you cannot move.
Most of this ground comes to us under brush. Our Llano clearing crew takes the timber off and the rock head follows on the same mobilization, one transport instead of two.
Most rock milling advice you read online is written for limestone. Llano sits on the Llano Uplift, so the material is decomposed granite and surface stone. It mills, it packs beautifully, and it does not behave like caliche.
Decomposed granite is what people truck in for paths and drives elsewhere. Milling it in place means you already own the surface material other counties pay to import.
Not everything out here mills. Where there is solid granite we will say so rather than spend your days finding out. That honesty is the whole reason we quote off photos before anyone mobilizes.
The machine, the days, and transport. Rock is slower than brush and how much slower depends on how hard it is and how deep you need it, which is why the quote reads in days rather than acres. Our published price page carries the rates the quote is built from, so you can check the logic yourself.
What kind of rock you actually have, first and foremost. Decomposed granite mills at a different rate to solid stone, and the honest answer often comes from the first pass. Photos texted to 512-400-2693 get a same-day ballpark.
We do not publish somebody else transport rates, so take this as the shape of the argument rather than a number. Digging rock out means an excavator, a loader, trucks, a place to put it, and then base material bought and brought back in. Milling replaces all of that with one machine and no trips. The fewer moving parts, the fewer lines on the invoice.
We do not sell, buy or deliver milled material, and we do not do lime or cement stabilization. If your plans call for either, we will point you at somebody who does it properly rather than learn on your job.
Quote first, walk after you approve it. Same order as every trade we run.

Machine days on paper: the machine, the rock head, the days, transport. Priced from ground we have already milled nearby.
Once you approve the estimate we walk it together: access, staging, where the material should end up, and what has to come off first.
The lowboy brings the machine and the rock head. We stage where you tell us and work around gates and stock.
The head takes the surface down in passes. You are welcome on site, outside the stay-back distance, and it is loud enough that we mean it.

The STC/SSL rock mill up close, and the reason for the stay-back stickerOutstanding operation! The big tree masticator ate cedar and mesquite standing as well as brush piles. Old trails cleared and widened. New trails created meandering through the property. Hardwoods left intact.

Cleared lots of cedars for trails for us on our 14 acres. Cannot wait to have them come back with the machine for rock pulverizing on the rock trails.

A great investment for our property. Showed up exactly when Preston said he would, worked hard all day long without a break with a beast of a machine. He had a very good understanding of what I wanted to do, and did it. The results are fantastic.

A rotating head with carbide teeth grinds surface rock, caliche and the soil around them down in passes, in place. What comes back is a graded mix you can spread and compact. Nothing is dug out, nothing is hauled off, and no material is brought in.
No. Crushing processes rock into sized aggregate to sell, spread or haul. Milling never separates the rock from the ground it came from. We mill.
No. We do not sell, buy or deliver millings, grindings or asphalt material of any kind. Everything we mill stays on the property it came from. If you are looking to buy material, you want an aggregate supplier.
Mechanically, yes. Grinding rock and soil together in place is what stabilization means before anyone adds a chemical, and the result is a blended subgrade you can compact. We do not do lime or cement treatment. If your engineer specified either, you want a stabilization contractor.
We mill decomposed granite and surface stone, which is most of what Llano County actually has near the surface. Solid granite is a different proposition and we will tell you straight rather than bill days against it.
It is one of the better surfaces you can have, and it is already on your property. It packs hard, drains well, and holds a crown, which is exactly why people elsewhere pay to have it delivered.
It depends on the rock and the machine. The head works the surface down in passes rather than one cut, so the honest answer comes from the first pass on your ground. The quote says how many days that is expected to take.
That is one of the most common reasons we get called. The milled fines bind better than loose rock and hold a crown, so a drive that used to wash out becomes one you can maintain with a box blade.
It can, because a milled and compacted surface sheds water in a direction you chose rather than wherever the rock decides. We shape fall into pads and drives while the head is on site, which is cheaper than fighting water afterwards.
ASV compact track loaders running an FAE STC/SSL skid steer rock mill. That is a dedicated rock head, separate from our forestry mulching heads and built for stone.
