We build and improve roads of every kind.
By engineering the soil and base already on site, we build new roads faster and make existing ones last longer — trusted across 50+ countries for roads, mines, energy sites, and airfields.
At work in the U.S., Canada, Morocco, Cameroon, Mongolia — and 50+ countries on every inhabited continent.
Three decades of proof — in the lab and in the field.
We engineer stronger ground. By optimizing the soil already on site, we cut the need to haul in imported rock — and where the native soil isn't enough on its own, we strengthen the base and sub-base so they carry more load. We don't compete with asphalt; we make it last longer by giving it a stronger foundation to sit on. Every project is different, and our technology is backed by both laboratory testing and decades of field performance across 50+ countries.
Countries actively using SCI technology, from Texas county roads to a 500-kilometer rural road program in Morocco.
Years of continuous water-based polymer R&D, developed with the University of Texas and Austin Technology Incubator.
Proprietary products spanning soil stabilization, dust control, pavement preservation, and roofing.
Petroleum hydrocarbon content and outgassing, independently tested — the platform is built around what happens after it hits the ground.
One platform, engineered for how each industry actually fails.
01 / EnergySolar & Energy
Access roads and equipment pads between solar arrays and LNG sites, built from the soil already on hand.
02 / RoadsUnpaved & Rural Roads
County and farm-to-market roads — a firm, dust-free surface without importing crushed rock.
03 / Ranch RoadsFarm & Ranch Roads
The access roads on working land — feedlots and staging areas with a firm, all-weather surface and far less dust.
04 / MiningMining & Heavy Haul
Haul roads and yards engineered to carry extreme loads with minimal maintenance.
05 / GovernmentMilitary & Government
Bases and staging areas that need a hardened, dust-free surface fast — no special handling.
06 / MunicipalMunicipal & Infrastructure
Subdivision roads and laydown yards — durable surfaces that lower long-term maintenance.
07 / AviationAirfields & Airstrips
Runways and shoulders on remote strips, where a firm surface protects aircraft and improves safety.
Engineered ground. Not guesswork.
Our proprietary, water-based technology transforms loose soil into a firm, load-bearing, water-resistant surface. The chemistry is ours — three decades of research — and we intend to keep it that way. What we will tell you is the result: stronger layers, water kept out, dust gone, and a foundation engineered to outlast the traffic it carries.
Discovery & Site Assessment
We evaluate your soil, traffic, and goals, then match the right product and dosage to the job in front of us.
Execution
Our crews apply the treatment with standard equipment — sprayed, mixed, and compacted into a finished, load-bearing surface.
Long-term Partnership & Maintenance
We stay engaged after the job, supporting performance and periodic maintenance so the surface keeps earning its keep.
Drag the line. The soil doesn't lie.


One water-based polymer. Seven proprietary products.
Every product is a manufactured liquid mixed with water and applied with standard equipment — no solvents, low petroleum hydrocarbon content, no special handling.
Top-Seal White
All-purpose soil stabilizer & sealantBinds the soil already on site into a firm, water-resistant, dust-free surface — often removing the need to import crushed base.
Top-Seal Black
Dark running surface for final & haul roadsA carbon-bearing derivative of TSW that leaves a dark, asphalt-like surface — without the hot mix or the emissions.
Haul Road Top-Seal
Heavy-load haul road dust & surface controlFeatured on the cover of Aggregates Manager magazine — sealing and dust control for quarries and heavy industrial sites.
Dust Control Program
Municipal & industrial dust suppressionTurns a daily watering expense into a managed one — a single sealing program holds the surface for the season.
Terra Prime
Eco-friendly prime & tack coatA low-odor, water-based alternative to cutback and emulsion primers — benchmarked by TxDOT, no kerosene, no flammability risk.
Terra Fog
Asphalt preservation fog sealSlows oxidation and keeps water out of the base, extending the life of aging asphalt — back to traffic in hours.
Terra Roof
Waterproof roof rejuvenation coatingRestores and waterproofs aged roofs — solar-compatible, does not void existing warranties.
Moving the immovable: heavy-haul roads for a Gulf Coast energy megaproject.
For one of the largest energy-construction projects on the Texas Gulf Coast, we stabilized native soil into heavy-haul roads and yards engineered to move some of the heaviest loads ever carried by road — multi-thousand-tonne process modules — with minimal maintenance.

What our clients say, worldwide.
SCI's products transformed our unpaved roads. No more dust clouds, and the surface has held strong through every season.
We were spending a fortune on daily watering. With the haul-road program, maintenance is minimal and the performance is unmatched.
The team guided us every step of the way. Our site is stabilized and our costs have come down.
What impressed us most was how environmentally safe the product is. It performs like asphalt — without the asphalt.

Sustainability isn't a marketing layer — it's the chemistry.
Water-based by design. One question drives every formula: what happens after it hits the ground?
Supported by independent environmental and geotechnical testing.
Independently tested, with extremely low petroleum hydrocarbon content compared to conventional petroleum-based alternatives.
Engineered to minimize outgassing after application, independently tested against conventional alternatives.
Far less to no heavy-metal contaminants compared to conventional petroleum-based primers.
Independently tested against petroleum-based primers, with substantially reduced environmental impact.
Firmer surfaces mean fewer water-truck passes and far less hauling of imported rock.
Thirty years of improving the soils of the world.
Soils Control International was founded more than 30 years ago on a simple idea: treat the soil that's already on site instead of hauling in expensive rock and laying down toxic asphalt.
The company was founded by a U.S. military veteran and university-trained engineer, and the technology was advanced in partnership with the University of Texas and the Austin Technology Incubator — the collaboration behind the dark-surface line. Three decades on, that water-based platform — engineered for low petroleum hydrocarbon content and outgassing — is at work on every inhabited continent and in more than 50 countries.
