Every contractor in Texas has stood on a jobsite after a wet week and done the same math: how long do I wait, and what will it cost me if I do not. A soft site does not fix itself on your schedule, and the wrong move makes it worse and more expensive. The good news is that stabilizing wet ground is a known sequence, not a guess. Find the bad spots, deal with them instead of burying them, separate the good material from the bad soil, get the water off, and build back up in lifts.
First, figure out what kind of wet you have
There is a difference between a surface that is slick and a subgrade that has lost its load carrying capacity. Surface wet dries. Saturated subgrade does not, at least not on any schedule you control.
The test is simple. Run a loaded truck or a heavy roller across it and watch. If the ground deflects and springs back, water is coming up as the wheel passes, or you see ruts forming and the material moving ahead of the tire, you have a subgrade problem. That is pumping, and no amount of rock placed on top will cure it by itself.
Proof roll before you place anything
Proof rolling is the cheapest test on the job and the one most often skipped when a schedule is behind. Drive a loaded vehicle across the area in a grid pattern and mark everywhere that deflects or ruts. Those marks are your work list.
Do this before material arrives, not after. Rock delivered onto ground you have not tested is rock you may be about to waste.
Undercut and replace the soft spots
When proof rolling finds a soft area, the durable fix is to dig it out and replace it with material that will carry load. Excavate to firm ground, then backfill with select fill or crushed base in compacted lifts.
Burying a soft spot under fresh rock is the tempting move and the expensive one. The soft area stays soft, the section above it flexes, and you come back to the same spot with a repair crew later.
Use separation fabric where the soil is bad
On saturated fine-grained soils, especially the expansive clays common across Central and East Texas, a geotextile separation fabric between the subgrade and the base does two jobs at once. It stops the stone from migrating down into the soft soil, and it stops the soil from pumping up into the stone.
That matters because contamination is what actually destroys a section. Once fines work up into your base, the base stops draining and stops behaving like base. Fabric is cheap compared to the rock it saves.
Choose material that drains and locks up
For rebuilding over wet ground, an angular, well-graded crushed material is what you want. Crushed limestone base and crushed concrete base are both common choices in Texas and both perform well.
Larger, more angular material placed as a first bridging lift can work well over very soft ground because it keys together and spans the weak spots, with a finer graded base above it to create a working surface. Rounded gravel is the wrong choice here because it moves under load instead of locking.
Get the water off, or you will do this again
Stabilizing without drainage is temporary. Crown the working surface so water sheds, cut ditches at the edges where grade allows, and pump the low spots rather than waiting on them.
Water standing at the edge of a pad or a haul road migrates underneath it and resaturates the subgrade you just fixed. Most repeat failures in Texas are drainage failures wearing a different hat.
Build back in lifts and compact each one
Place material in compacted lifts rather than one deep dump. A thick uncompacted layer traps moisture and never reaches the density you are paying for. Lift thickness depends on the material and the compaction equipment you have, so match them.
How much rock to order
Start with the geometry: length times width times compacted thickness in feet, divided by 27 for cubic yards, then converted to tons at roughly 1.9 to 2.1 tons per cubic yard for most crushed base.
Then add for reality. Add for compaction. Add for undercut volume you found while proof rolling, which is usually more than you first estimated. And add for the material that works down into soft subgrade on the first passes.
If you skip that last allowance you will be short, and being short in the middle of a weather window is how a one-day fix turns into a one-week fix.
Getting it delivered
Tell your supplier the conditions, not just the tonnage. Saturated clay subgrade, bridging lift over fabric, and a working surface above it are three different material calls. Confirm delivered cost per ton including haul, and confirm the delivery window, because a wet site with a narrow dry window needs trucks that show up when the ground is ready.
Burying a soft spot under fresh rock is the tempting move and the expensive one.
