CLEARING
Round Rock is named for a rock, which tells you most of what you need to know about the ground. The Balcones fault runs through it, so a site can be prairie clay on one end and Edwards limestone on the other. We mill surface rock in place with an FAE STC/SSL rock mill, grinding it and the soil around it into a blended, compactable subgrade. That is mechanical soil stabilization, and nothing leaves the site to get it.
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 Round Rock 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.
Commercial drives, laydown yards and ranch roads all get milled to a running surface. The milled fines compact rather than roll, so the surface holds under traffic instead of rutting after the first wet week.
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 Round Rock clearing crew takes the timber off and the rock head follows on the same mobilization, one transport instead of two.
Most people asking about soil stabilization around Round Rock have a subgrade that will not compact because rock and soil are sitting in layers rather than mixed. Grinding them together in place fixes that mechanically. If your engineer specified lime or cement, that is a different contractor and we will say so.
The fault line means a site can dig like farm ground at one corner and stop a bucket at the other. Pricing a whole site off one test spot is how change orders happen.
Round Rock work skews commercial: pads, laydown areas, drives that have to carry loaded trucks. Milled and compacted subgrade is cheaper than importing base and it does not wait on a delivery schedule.
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.
Hardness and depth first, then how much surface has to be covered and how far the machine walks between areas. Round Rock is a short run from our yard, so transport stays a small line. 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.

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.

These days it is unusual to find services that are adequate, let alone exceed expectations. We had a very challenging project which required working around hundreds of boats on trailers, preserving legacy trees and navigating steep drop offs.

This company gets customer service. They promptly contacted me, scheduled service within the week and promptly showed up each day of the project. The operator listened and provided fabulous service. Our 2 acre grading was done to our specs.

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.
Mechanically, yes. We grind rock and soil together in place with the rock head, which produces a blended subgrade you can compact. We do not do lime or cement treatment. If your plans specify a chemical stabilization spec, you want a stabilization contractor.
Yes. The machines are compact track loaders, so they fit sites where a scraper spread does not, and we work around other crews. It is loud, so we agree the days in advance.
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.
