Roads that don't wash away.
We harden the soil already under your road with ECOENZYME-TERRAIN, a bio-enzyme stabilizer made in Cameroon for every road we build. It turns the road waterproof and holds through the rainy season.
Free soil test, then a written price. No obligation.
We build roads. We also sell the stabilizer, by the drum, across CEMAC. See the product

What is ECOENZYME-TERRAIN?
An organic, bio-enzyme soil stabilizer. We make it ourselves at Bio-Forge, our plant in Mutengene: concentrated enzymes from our exclusive partner Infinita Biotech of India, blended and standardized here into a 100% organic liquid, tuned to Cameroon's laterite and volcanic clay. The plant opens before our first road.
Mixed into the road bed, it binds the soil together. The soil packs hard and turns waterproof. Rain runs off instead of soaking in.
Made in Cameroon, for Cameroon's red laterite. Our plant in progress
- 1Test the soil.
A lab reading sets your price. - 2Correct it if needed.
Wet ground gets limestone or gravel. - 3Rip and grade.
Graders loosen and shape the existing road bed. - 4Mix in ECOENZYME-TERRAIN.
Water trucks spray it on. Graders work it in. - 5Compact and cure.
Rollers press it tight. It hardens as it dries.
Save on cost. Keep the quality.
No gravel to quarry and haul. A stabilizer made in Cameroon. Your price is set by a lab soil test.
74%
At least 74% less spent on stabilizer than on cement
5×
Up to 5× longer than an untreated dirt road. No regrading every rainy season.
Based on published enzyme-stabilization data, Cameroon cement prices (2026) and gravel-road studies from Sub-Saharan Africa.
Cheaper doesn't mean weaker.
The savings come from the materials, not from building it lighter. Same strength, lower bill.
- Your soil is the material. No trucking in gravel or tar.
- Made in Cameroon. Every road we build uses stabilizer from our Mutengene plant, not finished product shipped across the world.
- Waterproof by design. The treated layer sheds rain instead of turning to mud.
- Built for Cameroonian soil. Our first field trial ran on a road in Olembe, Yaoundé.
Which are you?
92%
of Cameroon's roads are unpaved. We make them last.
Ministry of Public Works, 2021
For government & councils
More road for every public franc.
We work with the Ministry of Public Works (MINTP), which runs Cameroon's roads, and hold a contract with the Ministry of Housing and Urban Development (MINHDU) for urban roads. For farm-to-market roads we work with councils, SOWEDA, MINADER and plantation companies like CDC and PAMOL. We build the road, train your crews to build it, or supply the product.
- Stretch the budget.
- Up to 70% cheaper per km than asphalt. One allocation reaches more villages.
- Already working here.
- Under contract with MINHDU. First field trial done in Olembe, Yaoundé.
- Paper you can file.
- Lab soil report with every quote. Specifications and method on request.

Is it asphalt?
No. It hardens the soil itself. You can pave on top later.
Will it work on my land?
It needs clay, roughly 15 to 20% or more. Most laterite has it. We test first and tell you straight. Sandy ground can often be corrected.
Is it safe near crops and water?
Yes. It's plant-based, non-toxic and biodegradable.
How long does a job take?
It depends on length and soil. Your quote comes with a schedule.
When is the best time to build?
The dry season. The treated soil needs sun and a few dry days to cure, so we schedule around the rains. Book early and we hold your slot.
When can I drive on it?
Light traffic after 24 hours. Full use about 72 hours after we finish compacting.
Do you work in my region?
Yes. We have teams in the Southwest, Northwest, Littoral, West, South and East. Elsewhere, ask us.
If it's cheaper, will it really last?
Yes. Up to 15 years: as long as many paved roads here, and up to 5× longer than untreated dirt roads. It costs less because we use the soil already there and make the stabilizer in Cameroon, not because it's weaker.
Who makes ECOENZYME-TERRAIN?
We do, at Bio-Forge in Mutengene. The enzyme concentrate comes from Infinita Biotech of India. The blending, hydration and quality control happen here.
Can I buy ECOENZYME-TERRAIN on its own?
Yes. By the drum, with training for your crew if you want it, anywhere in CEMAC. Ask for a product quote.
What does it cost?
Your price is set by a lab soil test. Driveways and lots are quoted per site.
