Real ranges by pad size and fill depth, what actually moves the number, and what's specific to building pads in South Texas — no lead-gen games, just the numbers.
These are typical Rio Grande Valley market ranges, not a quote. Your actual price depends on your lot's fill depth, access, and drive length — this table is the starting point for a real conversation.
| Pad size | What it looks like | Typical cost |
|---|---|---|
| Small (house, ~1,600 sf) | Minimal cut/fill, shallow fill depth | $5,000 – $9,000 |
| Mid (barndo/shop, ~3,600 sf) | Several inches to a foot of fill, standard compaction spec | $9,000 – $16,000 |
| Large (shop + yard, 8,000+ sf) | Deeper fill, larger footprint, more compaction passes | $16,000 – $25,000 |
| Caliche drive add-on | Base laid and compacted, priced per 100 ft of drive | $1,500 – $3,500 / 100 ft |
The ranges above are wide because "a pad" isn't one thing. Here's what actually pushes a quote up or down.
A pad needing 6 inches of fill costs less than one needing 3 feet — depth is the single biggest driver of material and compaction cost.
A shop or barndo foundation calls for a tighter compaction spec than a gravel yard pad — spec drives both time and testing.
Fill has to come from somewhere. The farther it's hauled to your lot, the more trucking shows up in the number.
Larger pads use more material overall, but the per-square-foot rate often comes down as the job scales.
A caliche drive is priced by the foot — a long rural approach adds real cost beyond the pad itself.
Easy equipment access keeps cost down; tight lots or extra grading to fix drainage add time.
South Texas ground comes with its own cost drivers — worth knowing before you compare a quote here to a number from somewhere else.
Caliche and clay, close to the surface. Caliche hardpan sits a few feet down across much of the Valley, and it changes how a pad compacts and how deep fill needs to go before it's stable. Clay pockets nearby behave differently — they hold water and can shift a pad if they're not addressed before fill goes in.
Flat ground means the slope is built, not found. Most of the Valley is flat, which keeps grading simpler than hillier markets, but it also means a pad's drainage slope has to be built in on purpose. A pad that isn't sloped is just a place for water to collect.
Summer rain windows affect scheduling. The Valley's rainy stretch can turn bare fill to mud fast, which is why fill and compaction work gets scheduled around it rather than through it.
