What I check first on an Alton lot
In Hidalgo County, a house outside the mapped floodplain can still flood, and many do when storm water drains too slowly and ponds until it gets inside. So the first thing I look at in an Alton yard is where the water runs when it rains, and whether the new slab will carry it away from the house or toward it.
Next is the subgrade, the dirt the slab sits on. It's the part you'll never see and the first thing a tight budget cuts, so we dig it out and pack it rather than rake it level. If something has to give, I'd rather it be the finish.
The old concrete
Where there's a cracked or sinking slab already, I look at how it failed, because that usually tells me what the ground under it was doing.
Where the joints go
Control joints are cuts that give a slab a planned place to crack, so we lay them out before the pour and cut them on time.
Steel and thickness
Rebar, the steel bars inside the slab, holds cracked pieces together, and how thick we pour depends on whether it carries feet or a truck.
Room for the truck
I check where a concrete truck or pump can reach, since a tight side yard or a fence in the way changes how we set up the pour.

How we cover Alton from Mission
We're based in Mission and work in Alton and the other cities around it across Hidalgo County, the same as we do in Pharr and Palmview. We're licensed and insured, our crew does the work, and I'm on site with them.
I come out myself to look at the job and measure it. What moves the price is the size, how thick the slab has to be, how much base work the ground needs, the finish and whether old concrete comes out first, and the estimate puts your number on all of it.
The schedule turns on the permit, when your job needs one, and on curing, the wait while fresh concrete hardens before it can take weight. Have a rough idea of the size you want, where you park and any spot where water stands after rain.

Do I need a permit for a concrete driveway in Alton, TX?
Ask the City of Alton's Building Projects service, which is where permits are paid and inspections scheduled for construction inside the city, at 956-432-0730. When a job needs one, we handle the application and set the pour date after it's issued, and if it's unclear, we'll ask them rather than guess.
How long before I can drive on my new concrete driveway?
You can walk on a new driveway well before you can park on it, because it keeps curing for days after the pour. I'll tell you what to expect for both at the estimate, since the mix, the thickness and the weather that week all move those dates.
Will my new concrete patio crack like the old one did?
Most slabs get some cracks, and the aim is to keep them thin, tight and in places we picked. That comes from the packed base, the steel and the joints covered above, and when an old patio cracked all over, the base or the joints were usually what let it down.
Do you pour concrete in the middle of a hot day?
We plan pours for the cooler part of the day when we can, because concrete that dries too fast in midday heat can end up with a weak, dusty top. If a pour time has to move for that reason, I'd rather tell you early than leave you with a surface that chips.
What is a broom finish and does my driveway need one?
A broom finish is the light ridged texture we drag across fresh concrete so a driveway or walk has grip when it's wet. A smoother or stamped finish trades some of that grip for looks, so I'd keep the broom finish on anything people walk on wet.
