Flexible concrete mattress solution for reliable erosion and scour protection in hydraulic environments
Fabric-formed concrete mattresses solution is designed to provide durable erosion and scour protection for hydraulic, coastal, industrial and environmental infrastructure.
Combining a high-strength woven geotextile form with fine aggregate concrete, FFCM creates a continuous cast-in-place mattress that combines the durability of concrete with the flexibility required to conform closely to existing ground conditions.
Suitable for installation on land or underwater without dewatering, FFCM helps owners, engineers and contractors reduce construction constraints while achieving reliable long-term hydraulic protection.
Key characteristics:
- Installation on land or underwater
- Flexible cast-in-place concrete mattress
- Engineered configurations for site-specific needs
- Adapted to hydraulic and geotechnical conditions
Hydraulic environments demand protection solutions capable of adapting to changing conditions
Rivers, canals, shorelines and hydraulic infrastructure are constantly exposed to changing water levels, current velocities, wave actions and scour mechanisms.
Owners and designers require protection solutions capable of maintaining protection efficiency throughout the structure lifecycle while minimizing installation constraints, maintenance requirements and environmental disturbance. Common project challenges:
- Scour around structures and foundations
- Bank and slope erosion
- Hydraulic uplift pressures
- Installation in flowing water
- Variable terrain conditions
- Long-term durability requirements
- Environmental integration objectives
- Construction time and cost constraints
Designed to combine the durability of concrete with the adaptability of a flexible mattress
FFCM uses a fabric formwork filled with fine aggregate concrete to create a continuous cast-in-place protection layer.
Unlike conventional rigid revetments, the mattress remains capable of conforming to the underlying ground profile while delivering the durability and hydraulic resistance of concrete.
This combination helps maintain continuous contact with the protected surface, limiting erosion pathways, mitigating scour development and improving overall stability.
Available in several engineered configurations, FFCM can be customized in thickness, weight, geometry and articulation to meet project-specific hydraulic, geotechnical and environmental requirements. FFCM is engineered to deliver:
- Continuous erosion and scour protection
- High resistance to hydraulic loading
- Adaptation to irregular ground profiles
- Reduced uplift and seepage effects
- Long-term durability
- Customized engineering for project-specific requirements
