SLSU secures Patent for Innovative Pervious Concrete Gabion System
Southern Leyte State University (SLSU) proudly celebrates another milestone in research and innovation following the successful grant of a patent for the invention entitled "A Pervious Concrete Gabion System." The patent, officially granted by the Intellectual Property Office of the Philippines (IPOPHL) on February 6, 2026, recognizes the University's commitment to developing practical technologies that address real-world engineering and environmental challenges.
The patented invention was developed by Dr. Angel T. Sabusap and Engr. Christopher C. Arbiol, whose collaborative work introduced an enhanced gabion system designed to improve the stability, durability, and performance of conventional erosion control structures. By incorporating a snag-fit arrangement of pervious concrete blocks within a wire mesh cage, the innovation increases structural mass, enhances resistance to soil pressure, minimizes bulging, and prevents the accumulation of foreign materials without compromising the system's permeability and flexibility.
Designed for bridge abutment protection and stream bank erosion control, the Pervious Concrete Gabion System offers a sustainable and resilient solution for infrastructure projects. Its permeable concrete design allows efficient water flow while maintaining structural integrity, making it a valuable technology for climate-resilient and environmentally responsible engineering applications.
Beyond its technical advantages, the invention demonstrates strong potential for commercialization within the construction and civil engineering sectors. The technology supports sustainable infrastructure development by providing an effective alternative to traditional gabion fillers, contributing to resource conservation and improved environmental management.
This patent serves as another testament to SLSU's dedication to advancing research, innovation, and intellectual property generation. As the University continues to cultivate a culture of innovation, achievements such as this reinforce its role in creating technologies that generate meaningful impact for communities and industries alike.
Southern Leyte State University extends its heartfelt congratulations to Dr. Angel T. Sabusap and Engr. Christopher C. Arbiol for this outstanding accomplishment. Their achievement exemplifies the University's pursuit of excellence in research and its commitment to developing innovative solutions that contribute to sustainable national development.
