Black, heavy clay under a Hallsburg slab
The Texas State Historical Association places Hallsburg in eastern McLennan County, and Texas Parks and Wildlife says the Blackland Prairie reaches into the eastern part of the county. There, Upper Cretaceous chalks, marls, limestones and shales gave rise to the region's black, calcareous, alkaline, heavy clay soils. With no soil sample from Hallsburg itself in our sources, each lot gets a look first.
For Houston Black clay, a Blackland Prairie soil, the Soil Science Society of America's booklet says building on it is often plagued by cracking, that hydrated lime often goes in to stabilize it, and that foundations built on it need steel.
Fill and steel under the residential code
The International Residential Code has fill under a slab compacted, and caps it, unless approved, at 8 inches when it is earth and 24 when it is clean sand or gravel. Reinforcement is kept in the band from the slab's center to its upper third while the concrete is placed.

Slab costs and clay: questions
How much does it cost to build a 1500-square foot concrete slab?
None of our size tables lists 1,500 square feet exactly. National 2026 figures put a slab-on-grade foundation at $6 to $14 a square foot, typically 6 inches thick for a house, and another national 2026 table prices foundations of 800 to 2,400 square feet at $4,000 to $33,600.
How much does it cost to build a 20x30 metal building with a concrete slab?
The building itself isn't in the price figures we use, so only the slab can be answered here. A Waco-area estimate, undated, puts a light-duty 20 by 30 foundation at $9,327 to $11,387 and a heavy-duty one at $11,387 to $39,197.
Why does the soil survey rate Houston Black clay poorly for slab homes?
Because of its high shrink-swell potential. For dwellings on concrete slab, the McLennan County soil survey's rating for Houston Black clay is "Very limited" for that reason, and NRCS lists it at 54 to 55 percent clay in every layer, with a linear extensibility (its shrink-swell measure) of 12 percent.
