Hardened haul roads, built from the soil in place
Mines, quarries, forestry, landfills: your surfaces take heavy loads, dust and washout. LL-TEQ™ stabilizes in-place materials with an organic polymer to build hardened haul roads and platforms, with no bitumen, no asphalt plant and no imported aggregate. Technology deployed on five continents under the LANDLOCK™ and OPSDIRT brands.
Your top requirement
A load-bearing surface, built with your own fleet
No asphalt plant, no aggregate hauled to site: the polymer integrates into the gravel, sand, laterite or crushed base already in place using a grader, reclaimer, water truck and compactor, the equipment you already run. Verification relies on established references: CBR, compressive strength (PSI), 95% Proctor compaction and lab-measured permeability.
Dust control
Fines encapsulated: the water truck goes away
The LL25 surface seal acts as a dust palliative for PM2.5 and PM10 compliance: it encapsulates fines instead of letting them lift. On landfill sites and storage pads (California, Illinois), haul roads and platforms stayed free of dust and post-rain washout, removing daily watering and the repeated grading of gravel tracks.
What changes on site
Build with what the site provides
Return to service
Over 2 km/day of complete 2-lane rebuild with a single reclaimer, and return to traffic from 12 hours after placement depending on conditions. Your trucks keep rolling while the layer cures.
In-place materials
Native gravel, sand, laterite or crushed base: the formulation adapts to the soil at hand. Zero aggregate hauled to remote sectors, zero hot-mix logistics chain, fewer haul trips.
Heavy loads
Built for high-tonnage haul-road stabilization: 1,625 PSI compressive strength, several-fold CBR gain on the treated soil, and k = 3.6 × 10⁻⁸ cm/s permeability that resists washout under rain and the traffic of haul trucks and loaders.
Reference case · Mines & quarries
Mine haul roads, washout and dust eliminated
Copper mine, Panama (2019): crushed base and native soil reclaimer-integrated into a hardened haul road that eliminated washout and dust under heavy-truck traffic, without hauling aggregate to site.
The same process hardened a roughly 10,200 m² coal haul road at La Guajira (Colombia, 2013), where coal-dust control was the priority, plus roughly 18,400 m² and 29,300 m² of landfill haul roads (California, Illinois) from in-place soil and crushed concrete.
Resource & forestry roads
All-season access on the gravel in place
Forestry roads, resource roads and gravel networks: the polymer stabilizes the gravel or laterite wearing course where it lies, without hauling aggregate to remote cutblocks. The UNRA (Uganda) trial section showed the treatment outperforms untreated gravel as a wearing course and was recommended for the country's 20,000 km unpaved network.
Under accelerated MMLS loading (2.7 kN wheel, 7,200 wheels per hour, with water and lateral wander applied), the treated surface resisted rutting. The field result: less rutting, less washboarding and less dust on truck-heavy roads.
Erosion control
A surface that sheds water instead of washing away
The polymer encapsulates and binds the fines into a cohesive, water-resistant matrix: permeability drops by about an order of magnitude (k = 3.6 × 10⁻⁸ cm/s, ASTM D5084), so rain sheets off instead of soaking in and cutting rills and gullies. In simulated-rainfall testing (50 mm/h, EPA methods) the runoff from the treated surface stayed clear, with little soil loss and no acute aquatic toxicity, while untreated soil shed turbid, sediment-laden runoff. Proven on slopes, berms and a storm channel: 7.3 ha of slope stabilized in 3 days at USMC Twentynine Palms, plus a storm-channel section at Sierra Army Depot.
For your sector
Concrete benefits, sector by sector
Mining
Haul roads that take loaded trucks without rutting or washout, and dust suppressed (PM10) on extraction tracks. Proven on a copper mine in Panama and a coal road in Colombia.
Forestry
All-season access to cutblocks on the gravel in place, with no aggregate hauled to remote roads and far less washboarding and dust.
Quarries & aggregates
Internal roads and stockpile pads hardened from on-site material, with dust controlled at the source and less wear on tires and fleet.
Landfills & waste
Haul roads and cell access stabilized from in-place soil and crushed concrete, with no erosion after rain. Proven on sites in California and Illinois.
Energy & construction sites
Hardstands, service areas and laydown yards that resist heavy-equipment loads, dust-free and low-maintenance, from the soil at hand.
Remote access roads
Access roads to remote facilities hardened from local soil, passable year-round and back in service from 12 hours after placement.
