What Happens When an RV Parks on a Four-Inch Slab
A fifth wheel does not load a driveway the way a car does. The weight is concentrated, it sits for months, and here the ground is softest just then.

Driveway Replacement and Removal in Conroe
Taking out a driveway that has reached the end of its life, dealing with what is underneath it, and pouring a slab that does not repeat the same failure.
Replacement is a different job from a new pour, and most of the difference is in the first day. Breaking out an old slab tells you why it failed, and that information is worth more than the demolition itself. A slab that comes up in large clean pieces with firm sand underneath failed from surface wear or age. One that comes up over a hollow, or over wet clay that has been holding water for years, failed because of what was under it, and pouring a new slab into the same hole produces the same result on a slower clock. The other thing demolition exposes is depth. A great many older driveways around Conroe were placed thinner than four inches, or placed straight onto uncompacted spoil left over from house construction, and that shows up the moment the breaker goes through. A replacement quote that has not looked at any of this is a guess about the part of the job that matters most.
What the work covers
- Existing slab broken out and hauled off, with the reason for the failure noted while the subgrade is open and visible
- Subgrade proof-rolled after removal so soft spots show themselves before anything is poured on them
- Soft or organic material dug out and replaced with compacted select fill rather than bridged with extra concrete
- Drainage corrected while the ground is open, which is the one window where regrading is cheap
- Utilities located before breaking, since older driveways frequently have irrigation lines, gas services, and cable runs beneath them
- Thickness and joint layout revised from what was there, rather than reproduced, when the old layout was part of the problem
- Garage apron, sidewalk, and street or culvert tie-ins reset to grade so the new slab meets everything cleanly
- Site left graded and cleaned, with the removed material disposed of rather than stockpiled on the lawn
For square-foot ranges and what moves them, see the Conroe concrete cost guide, or run rough numbers on the driveway estimator.
Replacement: what homeowners want to know
How do I know whether to repair or replace?
Count the cracks and look at what they are doing. A slab with two or three tight cracks and no elevation difference across them is a repair candidate, and sealing or partial-panel replacement handles it. A slab where the pieces have moved relative to each other, where you can catch a shoe on an edge, or where cracking runs through most of the panels, has lost the structure that made it a slab and repair only buys a season. The guide on repair versus replacement on this site sets out the specific things to look at before deciding.
Can just one section be replaced instead of the whole driveway?
Yes, and it is often the sensible choice. Concrete is placed in panels separated by joints, and a single failed panel can be cut out at the joints and repoured without touching the rest. The honest caveat is colour: a new panel will not match a twenty-year-old one, and it will stay visibly different for a long time. Where appearance matters, that trade is worth weighing before the saw comes out.
How long does a driveway replacement take?
For a typical residential driveway, demolition and haul-off is usually a day, subgrade and forming another day or two depending on how much has to be dug out and brought back, and the pour is a single morning. Then the waiting starts. The site work is short and the cure is not, which is why the calendar question people care about is when they can park on it again rather than when the crew leaves.
What happens to the old concrete?
It goes to a recycling yard or a disposal site rather than a landfill in most cases, since broken concrete is a saleable material that gets crushed into aggregate and road base. Haul-off is a real line item on a replacement quote because it is real weight, and a driveway of any size is measured in tons, not truckloads.
Will the new driveway sit at the same height?
Usually close to it, but not always exactly. If the old slab was too thin, the new one will be thicker, and if drainage was part of the problem the finished grade may deliberately change to move water somewhere better. What matters is that the garage threshold, any sidewalk, and the street or culvert connection still meet the slab cleanly, and those tie-in elevations get set before the forms go in rather than adjusted afterwards.

Seal the Joints Before December, Not After April
On sandy Montgomery County subgrade, water under a slab takes the support with it. Sealing joints is the cheapest effective driveway maintenance there is.
How Wide Should a Driveway Actually Be?
Driveway widths were set decades ago for cars that no longer exist. A modern pickup is wider than the lane, and widening during a replacement is cheap.
Other Concrete Work
Work that usually gets quoted at the same time
Concrete jobs cluster because the expensive parts are shared. The truck is already coming, the forms and the crew are already on site, and the subgrade work has already been done. Pouring a walk, an extra parking pad, or a patio in the same visit costs far less than bringing everything back for it in a year.
