On a developed lot like many in Forest Hill, the ground under a new slab may have carried something before: a house, a road, a utility trench or an earlier pad. We treat that history as a subgrade question to answer before a price is final. Probing, testing and moisture checks tell us whether the soil can be proofed and compacted in place or must be removed, treated or replaced, and that answer is the largest single driver of slab performance.
The land area of Forest Hill is 4.17 square miles, sitting 653 feet above sea level, and both Kennedale and Everman lie about four miles off. With a footprint that small and neighbors that close, we expect many projects to be infill pads, redevelopment sites or additions to existing property, where old fill, buried lines and drainage that crosses boundaries are common.
We schedule, coordinate, supervise and inspect the earthwork, soil treatment and concrete trade partners, so the engineer, the owner and the building department see one coordinated plan.
Owners of infill and redevelopment pads
Commercial developers use us for retail and service buildings on lots that were previously used, and municipal and public works departments call for sidewalks, ramps, drive approaches and drainage structures. Both groups need documented subgrade preparation, because a later settlement claim requires proof of how the base was built.
School service is divided between Everman ISD and Fort Worth ISD, and O. D. Wyatt High School is among the Fort Worth ISD campuses that serve the city. Education owners add classrooms, bus lanes, walks and parking to existing campuses, and those projects carry the same infill challenges plus occupied-site safety rules.
How subgrade conditions affect the price
On an infill lot, the unknowns are removal of old foundations or pavement, the depth of fill and the moisture condition of the clay. We carry allowances for those unknowns when the geotechnical report is thin and tell the owner exactly what triggers a change. If the borings are good, we price the work firmly and do not hide behind contingency.
Treatment decisions can cost less than replacement. Mixing lime into the upper layers of clay often reduces swell and gives a working platform at a lower price than hauling soil away and importing select fill. The engineer decides, and we provide both prices.
Testing is its own line. Density tests, moisture checks, proof rolling and cylinder breaks are priced by frequency, and the specification sets the frequency. We follow it and tell the owner if we think a critical area deserves more tests than the minimum.
Working among neighbors and old utilities
Infill sites sit close to homes, streets and buried lines. Before digging we call for locates, hand dig at crossings and fence the work area. Dust control and wet cutting protect neighbors and workers from silica and lime dust, and we stop spreading treatment materials when the wind picks up.
We also schedule deliveries to avoid peak school and commuter traffic, protect sidewalks and keep a flagger on duty when trucks back in. A short safety briefing opens each day on site.
Heat and hydration plans cover summer placements, and cold-weather plans cover frost. We carry first-aid supplies, keep emergency contacts posted and make sure every worker knows the nearest route out of the site.
Services around a slab on old ground
A slab on reworked ground often needs over-excavation and recompaction, lime and cement soil treatment or engineered fill and soil stabilization. We choose among them with the engineer based on test results, not habit.
We also handle demolition and removal of old slabs and foundations, concrete demolition and removal, so the debris is hauled, the area is graded and the pad is ready for new work without a second contractor in the middle.
Sequencing treatment, testing and pours
Soil treatment adds waiting time. Lime mixed into clay needs mellowing days before final compaction, and cement treatment has a short working window. We schedule the treatment, the compaction tests and the base placement so the pad does not stand open to rain, and we place the slab only when the engineer accepts the base.
Ready-mix is ordered after the final subgrade check, with a backup plan if rain intervenes. In summer, we start early and keep moisture on the subgrade just before placement so the dry soil does not pull water from the concrete.
Growth, rail history and a stable population
Forest Hill counted 12,355 people in 2010 and 13,955 in 2020, and the 2025 estimate is 14,056. Growth that slows is typical of a built-out community: new construction is more likely to replace or expand than to open raw land, so the work is more about renovation, additions and public improvements.
An electric railway, the Fort Worth Southern Traction Company line running between Fort Worth and Cleburne, had a Forest Hill stop by 1911. The line is long gone, but old rail grades and cuts sometimes remain under modern streets, and we review historical maps and survey data for rights of way before we dig.
What we build on a Forest Hill pad
A typical package includes demolition of what is there, grading, subgrade treatment, base, vapor barrier, reinforcing and the slab, plus curb, gutter, sidewalk and parking. We lay out joints to match the building columns and the parking plan, and we install block-outs for plumbing before the pour.
Public work adds ramps, driveways, storm inlets and short runs of pipe. We build them to the owner's standard details, keep the inspector informed and provide test results at closeout.
For municipal work, we usually coordinate with a public works inspector who may want to see subgrade, forms and steel before each pour. We schedule those inspections ahead and keep a log so a dated record exists for each one.
Send us the Forest Hill soil report
Send the geotechnical report, the survey and the project schedule for your Forest Hill site. We will return a price that separates demolition, subgrade work, base and concrete, with allowances called out. We also work in Arlington, Fort Worth and Burleson, and can add concrete testing and quality control to the scope.
Common Questions
How do you evaluate subgrade on a previously developed lot?
We read the geotechnical report, probe the area for fill and old foundations, and test density and moisture. If the results are uncertain, we ask the engineer for additional borings. Then we decide whether to proof roll, treat, undercut or replace the soil.
Why does moisture matter so much under a slab?
Clay soils shrink when dry and swell when wet, and those changes lift or drop a slab unevenly. Keeping moisture steady through drainage, a compacted base and a vapor barrier helps the slab stay flat. We also cure the concrete properly so it reaches strength without cracking.
Can you remove an old foundation and build a new one in one contract?
Yes. We coordinate demolition, hauling, grading and new concrete under one schedule, which saves time and avoids gaps in responsibility. Disposal and testing are shown as separate items.
What testing will I receive at closeout?
You will receive compaction results for subgrade and base, concrete delivery tickets, slump and cylinder breaks, and inspection records. If treatment was used, you also receive the treatment depth and mix verification.
