In the face of rising sea levels, unpredictable flooding, and the constant force of hydraulic currents, traditional erosion control methods are reaching their limits. Rigid concrete slabs crack under pressure, and loose riprap often washes away during extreme weather.

The industry is shifting toward a more resilient, adaptive solution: Geosynthetic Formwork. Often referred to as a Flexible Concrete Mattress, this “flexible armor” is revolutionizing how we approach slope protection and scour protection in water conservancy projects worldwide.

What Makes Geosynthetic Formwork the “Ultimate Armor”?

Unlike traditional methods, Fabric Formed Concrete Revetment systems utilize high-strength, double-layer textiles as a “mold” for concrete. Once these forms are positioned—even underwater—a specialized grout is pumped into them. The result is a custom-fitted, monolithic shield that provides immediate and long-lasting erosion control.

However, no two projects are the same. Depending on the water velocity, soil conditions, and environmental goals, engineers can choose from four primary product types:

---

1. Uniform Cross Section (UCS) Mattress

The Uniform Section mattress is designed for maximum strength and a smooth, consistent finish. It creates a solid, near-impermeable concrete slab that is ideal for:

• High-velocity drainage channels.
• Spillways and culverts.
• Industrial lining where a low-friction surface is required.It provides a robust, heavy-duty barrier that effectively blocks external water from penetrating the subgrade.

2. Filter Point (FP) Mattress

The Filter Point mattress is the industry standard for slope stability. These mattresses are woven with small, concrete-free “points” at regular intervals.

• Key Feature: Permeability. These points act as natural pressure-relief valves.
• Performance: They allow groundwater to drain out from behind the mattress, reducing hydrostatic uplift pressure that could otherwise buckle the concrete. It is the perfect balance of heavy armor and water management.

3. Articulating Block (AB) Mattress

For projects where the ground is unstable or prone to significant settlement, the Articulating Block (AB) mattress is the premier choice.

• The “Flex” Factor: These mattresses consist of concrete blocks connected by narrow, flexible fabric “hinges.”
• Scour Protection: If the soil at the toe of the slope washes away, the AB mattress can “articulate” (bend) to follow the contour of the scour hole, self-healing the gap and preventing further erosion.

4. Enviromat (Vegetated Mattress)

In modern engineering, “green” is just as important as “strong.” The Enviromat is a specialized geosynthetic formwork designed to support vegetation.

• Eco-Friendly: It provides a stable lattice for concrete while leaving large open areas for soil and seed.
• Result: You get the structural integrity of concrete combined with the natural aesthetics and habitat benefits of a grassy slope. It is the ideal solution for urban riverfronts and environmentally sensitive areas.

Why International Engineers Specify Our Flexible Armor

• In-Situ Construction: No need for expensive cofferdams or dewatering. Concrete is pumped directly into the forms underwater or on slopes.
• Logistics Efficiency: Unlike pre-cast blocks, un-filled fabric forms are lightweight and compact. One 40HC container can carry enough material to cover thousands of square meters.
• Longevity: Made from UV-resistant, high-strength synthetic fibers, our Geosynthetic Formwork is built to withstand the harshest aquatic environments for decades.
