ITEM 515 | Geogrid
Geogrids are flexible woven geogrids fabricated with high molecular weight and low-creep polyester (PET) yarns, which provide a wide range of tensile strength for different soil reinforcement applications. Geogrids are uniformly coated with protective, non-toxic substances to enhance their overall resistance to abrasion, ultraviolet light, weathering, acid, alkali, biodecomposition, and other possible external conditions that may affect product performance. The geogrids are highly stable and durable against UV light and weathering (proven in both lab and outdoor tests).
Build more efficiently and sustainably than with standard methods.

Flood Control Protection Project Along Bangut River,
Capas, Tarlac
BEFORE
AFTER
​
CAPAS TARLAC – GEOTEXTILE TUBE
Bangut River in Capas, Tarlac, is crucial for local agriculture but poses significant flooding risks during typhoons and heavy rains. The rising water levels frequently lead to flooding of adjacent farmlands, threatening crops and disrupting farming activities. The area features loose, sandy soils on the riverbanks, a tropical climate with intense rains and typhoons, and flat terrain that is prone to overflow.
​
Solution: Geotextile Tube Flood Control
​
To mitigate these flooding issues, the project utilizes geotextile tubes—large, cylindrical containers made of durable fabric filled with sand or soil. These tubes are designed to create a robust flood barrier. The solution involves:
​
-
Site Assessment: Detailed surveys of hydrology, soil properties, and sediment transport to pinpoint critical areas needing protection.
-
Design and Planning: Selection of appropriate geotextile tubes and development of a barrier design to manage river overflow. Integration of drainage and erosion control measures.
-
Installation: Preparation of the riverbank, strategic placement of geotextile tubes, and backfilling for stability. Regular inspections and maintenance to address any issues.
​​
Benefits:
​
-
Effective Protection: Provides a strong barrier against flooding.
-
Quick Installation: Modular design allows for fast setup.
-
Cost-Effective: Affordable compared to permanent structures.
-
Low Environmental Impact: Minimally invasive installation.
​
​
The project demonstrates the effectiveness of geotextile tubes in managing flood risks and protecting agricultural lands from severe weather impacts.

AFTER
​
BALAYAN BATANGAS – GEOTEXTILE TUBE
Bais-Kabankalan Road is a crucial transport route in Negros Occidental, facilitating key economic and connectivity functions. However, certain sections of the road suffer from soil instability, leading to frequent slips and erosion that compromise safety and road functionality. The region's predominantly clayey and silty soils, combined with a tropical climate and hilly terrain, exacerbate these issues.
​
Solution: Geogrid Reinforcement
​
To address these stability problems, the project employs geogrid technology. Geogrids are geosynthetic materials with a grid-like structure that reinforce soil by distributing loads and enhancing stability. The solution involves:
​
-
Site Assessment: Conducting a thorough investigation of soil conditions and identifying critical areas needing stabilization.
-
Design and Planning: Selecting appropriate geogrid materials, designing layering configurations, and integrating drainage solutions.
-
Installation: Preparing the site, placing geogrid layers, backfilling, and compacting to ensure stability.
-
Monitoring and Quality Assurance: Regular inspections and adjustments to ensure the effectiveness of the geogrid reinforcement.​
​
Benefits:
​
-
Enhanced Soil Stability: Increased load-bearing capacity and reduced erosion risk.
-
Improved Road Safety: Stabilized foundation reducing accident risks.
-
Cost-Effective: Long-term savings through minimized repairs.
-
Durability: Extended infrastructure lifespan.
​
Challenges and Mitigations:
​
-
Material Degradation: Use UV-resistant geogrids and perform routine inspections.
-
Soil Variability: Customize geogrid designs based on specific site conditions.
