Scour Protection Mattress is a mesh mat specifically designed to protect dams from erosion and scour. It is stable and durable. The product is made of high-strength steel wire double-twisted woven together, and after being filled with stones, it forms a flexible, permeable structure that adapts to foundation deformation, effectively resists high-speed water erosion, and promotes vegetation growth. Construction is convenient, and the overall cost is low.
Product Advantages
Strong Adaptability
The Scour Protection Mattress's double-twisted flexible structure can withstand ±5% foundation settlement or frost heave without loosening or cracking.
Eco-friendly and Low-Energy Consumption
30% open porosity promotes natural vegetation succession, achieving ecological restoration and significantly reducing maintenance costs.
Efficient Assembly
Factory prefabrication and on-site stone filling simplify traditional wet construction processes and greatly optimize the overall construction period.
Durable Erosion Resistance
Resists erosion from rapid flows with velocities ≤3m/s, achieving 1.5 times the overall energy dissipation and erosion protection efficiency of traditional masonry.
Solution
|
Pain Points❌ |
Our Solution ✅ |
|
Hydraulic Erosion & Scour |
Superior Erosion Resistance This product can handle water flow speeds of four meters per second or less. It works by bending in a way to spread out the energy of the water. This helps to stop the slope from eroding and hollowing out. |
|
Surface Raveling & Loss |
Integrated Protective Layer The stones inside create a layer that lets water through. This layer is at least point three meters thick. Has lots of gaps. About thirty percent of it is empty space. It catches soil particles that might otherwise wash away. This helps to keep the soil in place with an efficiency of ninety percent or more. |
|
Structural Rigidity & Cracking |
Inherent Flexibility The mesh used here is made by twisting two wires into a hexagonal shape. This mesh can stretch by eight to twelve percent. This means it can handle changes in the ground beneath it like when the foundation settles or when the ground freezes and heaves. It can move with the ground without cracking. |
|
High Maintenance & Lifecycle Cost |
Long Term Durability and Cost Effectiveness This product uses a kind of wire that is coated with Galfan or PVC. This wire helps it to last for than fifty years. It requires no maintenance. This makes it a good investment. |
|
Hydrostatic Pressure Buildup |
Excellent Permeability With thirty percent of its space being empty water can flow through it easily. This helps to reduce the pressure of water behind walls by than eighty percent. This means that no holes are needed for drainage. |
|
Negative Ecological Impact |
Environmentally Friendly and Sustainable The empty space between the stones allows soil to form naturally. This soil helps plants to grow in just three to six months. The product blends in with the ecosystem, around it. It does this without needing landscaping. |
Construction process
Main Applications
Downstream abutment of dams: Energy dissipation and erosion prevention, preventing water flow from scouring the dam toe.
Riverbank protection and riverbed lining: Resisting flood erosion and maintaining bank stability.
Bridge pier perimeter protection: Preventing localized erosion that could hollow out the foundation.
Coastal dikes and groynes: Resisting wave and tidal erosion.
Spillway and stilling basin: Withstanding high-speed water flow impacts and preventing structural damage.
Quality Control
Material control at the source
Using low-carbon steel wire with a tensile strength of 350-550MPa. Upon arrival at the factory, the zinc coating thickness (≥245g/㎡) and adhesion (no cracking during winding test) are tested; batches failing to meet standards are returned.
Process Control
During the weaving process, the mesh size (tolerance ±3mm) and the length of the double twists (≥50mm) are checked every 2 hours. Edge wires are thickened by 0.5-1.0mm, and the partition spacing is maintained every 1m. Machines are stopped for adjustment if these tolerances are exceeded.
Finished Product Control
A tensile test is performed on every 500㎡ of mesh. Each batch of Galfan coating undergoes a 2000-hour salt spray test without red rust, and a CNAS report is issued.on
Delivery Control
Each package is labeled with a batch number; scanning the code allows for tracking of raw materials, production, and quality inspection data. Test reports are provided with the goods, and SGS and BV inspections are supported. Defects are replaced free of charge within the warranty period.
FAQ
Q: Can your company provide design support?
A: Yes. We can provide selection suggestions, structural calculations, and assist in drawing construction drawings based on your provided engineering parameters.
Q: How long is the product warranty?
A: We provide a ten-year warranty. We are fully responsible for problems caused by defects in materials or manufacturing processes.
Q: How is Scour Protection Mattress packaged and shipped?
A: Compression strapping reduces volume by half, making it ideal for sea or long-haul land transport. We offer professional packing solutions to ensure safe transport and lower costs.
