About
Three-Dimensional and High-Strength Woven Mats for Erosion Control
ACEMat™ R is a High Performance Turf Reinforcement Mat (HPTRM) developed to provide superior slope erosion control, vegetation enhancement, and long-term durability. Manufactured from high-strength polypropylene monofilaments woven into a three-dimensional mesh structures with rectangular pyramid patterns, ACEMat™ R delivers reliable performance in applications ranging from highway embankments and drainage channels to mining rehabilitation and shoreline protection projects. HPTRMs are a type of Rolled Erosion Control Products (RECP), also known as erosion control mat or geomat.
Soil erosion is one of the most common challenges affecting slopes, embankments, riverbanks, drainage channels, shorelines, and other exposed land surfaces worldwide. Heavy rainfall, concentrated water flow, wind, and human activities can gradually remove soil particles, resulting in unstable slopes, sedimentation, damaged infrastructure, and poor vegetation establishment. Without proper erosion control measures, erosion can continue to worsen, increasing maintenance costs and environmental impacts.
To address these challenges, engineers and landowners frequently use erosion control products designed to stabilize soil and protect exposed surfaces. Among these solutions, the anti erosion mat, also known as an erosion control mat, slope protection mat, or Turf Reinforcement Mat (TRM), has become one of the most effective methods for achieving long-term and permanent erosion control.
Unlike temporary erosion control blankets that gradually degrade over time, ACEMat™ R modern Turf Reinforcement Mats provide durable reinforcement that remains in place for years while supporting vegetation growth. These systems combine the strength of synthetic materials with the natural stabilizing effect of vegetation, creating a sustainable solution capable of protecting slopes under severe environmental conditions.

What Is an Anti Erosion Mat?
An anti erosion mat is a type of Rolled Erosion Control Product (RECP) designed to stabilize soil, prevent erosion, and promote vegetation growth on exposed surfaces. The mat forms a protective layer over the soil surface, reducing the effects of rainfall, runoff, and wind while creating a favorable environment for seed germination and plant establishment.
ACEMat™ R serves a specific purpose depending on site conditions, slope geometry, rainfall intensity, and project requirements.
Temporary erosion control blankets are often manufactured from natural materials such as straw, jute, or coconut fiber. These products are commonly used during early vegetation establishment and gradually biodegrade after installation. By contrast, ACEMat™ R Turf Reinforcement Mats utilize durable synthetic materials that provide long-term reinforcement. The three-dimensional structure reinforces vegetation and soil simultaneously, allowing the system to maintain erosion resistance long after vegetation established.

• Reduces carbon emissions (up to 96% CO2 reduction)
• Quick and easy installation
How Does a Slope Protection Mat Prevent Soil Erosion?
A slope protection mat works through several mechanisms that collectively reduce erosion and stabilize slopes.
First, ACEMat™ R protects the soil surface from direct rainfall impact. When raindrops strike bare soil, they loosen particles and initiate erosion. The mat acts as a protective cover, absorbing energy before it reaches the soil surface.
Second, the three-dimensional structure slows runoff water and reduces water flow velocity. By dissipating hydraulic energy, the mat minimizes soil particle detachment and transportation.
Third, the structure traps moisture and retains seeds, improving seed germination and vegetation establishment. Once vegetation develops, plant roots further stabilize soil and strengthen the slope.
Finally, the mat reinforces the root zone, helping vegetation withstand hydraulic forces that would otherwise uproot plants during heavy storms. The combination of soil reinforcement, vegetation support, and hydraulic protection makes ACEMat™ R Turf Reinforcement Mat highly effective for permanent slope erosion control.
Benefits of Three-Dimensional Woven Turf Reinforcement Mats
The performance of a Turf Reinforcement Mat depends heavily on its structure.
ACEMat™ R utilizes a three-dimensional woven system with rectangular pyramid patterns and a thickness of up to 7 mm. This structure creates a stable reinforcement layer capable of interlocking with soil and vegetation.
Key benefits include:
-
Enhanced Soil Stabilization
The mat stabilizes soil particles and reduces the risk of erosion caused by rainfall, runoff, and wind.
-
Improved Vegetation Growth
The open structure allows sunlight, air, and moisture to reach the soil while retaining seeds and promoting root development.
-
Permanent Erosion Control
Unlike biodegradable erosion control blankets, ACEMat™ R remains functional throughout the project life, providing continuous reinforcement.
-
Hydraulic Resistance
The reinforced structure dissipates water flow energy and protects channels and slopes from scouring.
-
Environmental Sustainability
The system promotes natural vegetation establishment and significantly reduces the need for concrete or hard armor protection systems.
Applications of Slope Erosion Control Mats
Slope erosion control mats can be used in a wide variety of applications.
Highway and Railway EmbankmentsTransportation infrastructure frequently includes steep slopes vulnerable to erosion. Turf Reinforcement Mats stabilize embankments and support long-term vegetation growth.
Drainage ChannelsDrainage channels are often exposed to concentrated runoff and high flow velocities. Reinforcement mats protect channel linings from erosion and scour.
Riverbanks and ShorelinesRiverbanks and shorelines experience continuous hydraulic forces. The reinforcement provided by erosion control mats helps maintain slope stability while preserving natural vegetation.
Mining RehabilitationMining projects often require permanent slope protection and vegetation establishment after construction. Turf Reinforcement Mats support ecological restoration while controlling erosion.
Landfills and Environmental ProjectsLandfill caps and environmental restoration projects benefit from reinforced vegetation systems that minimize erosion and improve long-term performance.
Long-Term Durability and Cost Effectiveness
One of the primary advantages of ACEMat™ R is its durability.
The mat is manufactured from high-strength polypropylene monofilaments with tensile strengths up to 60 kN/m. The material is resistant to ultraviolet degradation, oxidation, abrasion, environmental weathering. Installation is easy with anchors such as ACEPin™ T(earth anchor) or
ACENail™ (soil nails).
Compared with concrete blocks, shotcrete, and other hard armor protection methods, ACEMat™ R provides a cost-effective alternative that promotes natural vegetation while reducing maintenance requirements. In many projects, the use of reinforced vegetation systems can significantly reduce carbon emissions compared with conventional concrete-based solutions.
The performance of ACEMat™ R has been validated through internationally recognized testing programs:
1. Channel erosion test ASTM D6460This test is conducted by a third-party laboratory that simulates soil conditions after stormwater-induced erosion. When TRM is applied to protect the earthen channels, it absorbs the hydraulic force, shear forces, and overland flow, thereby reducing soil particle loosening.
2. Vegetation growth test ASTM D7322
The result of the test shows that in the same controlled environment, the germination rate, plant height and grass weight of the covered group are better than those of the control group without cover, it was confirmed that TRM is helpful for the germination of seed promoters and the ability of plant growth.
3. Scouring resistance test ASTM D7101
We simulate the test to evaluate the amount of soil sprayed or carried by runoff and rain splash; the test shows that the treatment group covered with ACEMat™ R contains more soil than the other. The outcome can prove that TRMs have a stronger anti-erosion ability.
