We buy trucks in San Antonio

Bexar County holds two integrated cement plants, and that is unusual. The 1604 Quarry and Plant reports one hundred and thirty-eight employees, operator of record Alamo Cement Company. Capitol Cement Plant and Quarry reports one hundred and forty-two, run by Capitol Aggregates. The 1604 Quarry itself carries another fifty.

What makes the pair unusual is that they sit inside their own market rather than shipping to it. Most plants serve a metro from twenty-five or thirty miles out. These are in the city they supply.

Alamo Cement was the San Antonio Portland Cement Company until 1979 and is controlled today by Buzzi Unicem. Capitol Aggregates has been a Zachry family business since 1957, built on a former lithium plant bought in 1963.

Beyond the cement, two more sites put trucks on the same roads. Toyota Motor Manufacturing Texas turns out a vehicle roughly every sixty seconds with more than three thousand seven hundred employees, on land where the company bought two thousand six hundred and seventy-eight acres and gave six hundred and seventy-eight of them back to the city as greenspace along Leon Creek and the Medina River.

The other is Joint Base San Antonio, the largest joint base in the Department of Defense, counting forty-six thousand five hundred and seventy-seven people across active duty, civilian staff, contractors and families.

So the fleet here is mixed in a way a single-industry town’s is not: mixers and bulk tankers off the cement, car haulers off the assembly line, and everything a base of that size needs delivered. Toyota alone gave back 678 acres along Leon Creek and the Medina River when it built.

All of those loads run under one statutory ceiling, and the cement side sits on the right end of the permit list.

Texas sets gross weight at 80,000 lb, a single axle at 20,000 lb and a tandem at 34,000 lb — the plain federal figures, with no commodity variance of the kind Georgia and Kentucky grant.

What Texas grants instead is permits, and each one is written for a named industry: ready-mixed concrete, fluid milk, timber, and super heavy single-trip. There is no permit named for aggregate, stone, sand or quarry products. So a stone hauler here gets the general permit and nothing else, while a ready-mix truck sits on the list — two trades a reader might treat as one, on opposite sides of the line.

The general permit adds ten per cent on the axle and five per cent on gross, and it comes with a bond and liability for actual damage to load-restricted roads. On a load-zoned road the permitted weight is ten per cent less than the maximum, so those two percentages run in opposite directions and must never be added together.

Tex. Transp. Code § 621.101; Chapter 623 permits. Information, not legal advice.

Beyond the weight rules, the paperwork is a single sentence.

Everything after that sentence is a fix rather than a category. A lost title has a counter replacement. Where none exists there is a bonded route. Both are ordinary and neither stops a sale.

One Texas rule is worth knowing because it runs further than any other state on file. Texas brands a truck salvage only where the cost of repairs exceeds the actual cash value before the damage — effectively one hundred per cent, against eighty in Florida and sixty in Oklahoma. And it is a two-part test, not pure arithmetic: there must also be damage to, or a missing, major component part.

The calculation leaves out repainting and sales tax, which no other state on file excludes. For a truck whose damage is mostly cosmetic that moves the answer a long way.

Tex. Transp. Code § 501.091. Information, not legal advice, and only as current as the date the rule file was last verified.

All of that iron is iron we buy. Mixers and bulk tankers off the 1604 and Capitol plants. Car haulers off the Toyota traffic. Dump trucks and aggregate haulers off the quarries, day cabs and road tractors, flatbeds, rollbacks, box trucks, straight trucks, service bodies, and the work trucks and pickups that go with a crew.

One local note worth having: Bexar County joins the state vehicle emissions inspection programme on the first of November, 2026. Diesel vehicles are not required to be emissions-inspected in Texas, so for most of the trucks on this page the answer does not change.

Whatever you drive, the offer doesn’t change. We buy all of them. Alamo Cement Company and Capitol Aggregates are where most of the heavy iron turns up.

• Does it have to run?No. It does have to be complete — if the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Rust is not a disqualifier.
• Does the new emissions rule affect selling my truck?Diesel vehicles are not required to be emissions-inspected in Texas, so for most trucks it does not. It is worth knowing about all the same.
• My mixer is out of a plant fleet. Interested?Yes. Mixers are ordinary here and we buy them.
• What about the title?We need one unless the truck is old enough that it never had one. Lost titles have a counter replacement; where none exists there’s a bonded route.
• How far out do you come?All of Bexar County and out into Medina and Atascosa. Distance has never stopped a sale.

Beyond a plant fleet turning over, the reasons are personal ones. Retiring. A medical that went the wrong way. A truck bought for a run that no longer exists.

Yards along the north loop and out toward Medina County usually have one waiting.

Most of those aren’t happy reasons, and we don’t treat them like they are. Somebody wants a straight answer and the truck gone by the end of the week. That’s what we’re here for. Out toward Medina County the same mixers come up for sale for the same reasons. Medina County yards and the Alamo Cement Company roads usually have one waiting.
