Efe Jessa, a Nigerian civil engineer, is transforming soil stabilisation in construction with bio-enzyme technology, offering a cost-effective and eco-friendly alternative to traditional methods.

A graduate of Delta State University, Jessa’s research into bio-enzyme stabilisation began in 2017, aiming to replace cement and lime-based treatments that contribute to carbon emissions.

His innovative approach, according to him, enhances soil strength, reduces water permeability, and lowers construction costs by up to 30%.

Speaking, he said, “For decades, construction projects have relied on conventional stabilisation materials such as cement, lime, and bitumen—solutions that, while effective, come with high costs and significant carbon emissions. My innovative approach leverages bio-enzymes, organic compounds that enhance soil strength, reduce water permeability, and improve long-term durability without the environmental drawbacks. Compared to traditional methods, bio-enzyme stabilization has proven to cut construction costs by up to 30%, reduce permeability by 70%, and significantly lower carbon emissions.”

He recounted the success of his method in a home project and how his contributions were recognised by the Delta State government.

“My method was successfully implemented in the Smart Home Project in Rumukparili, Rivers State, where it provided a durable and sustainable foundation for the housing development by Pointlink Property Services Nigeria Ltd. The project demonstrated the effectiveness of bio-enzymes in large-scale infrastructure.

“My contributions earned me a Certificate of Excellence from the Delta State Ministry of Works on September 19, 2018, recognizing his advancements in sustainable construction.”

Jessa’s work continues to improve soil stabilization methodologies, enhancing the sustainability and longevity of critical infrastructure.
