Eco-Slope Retaining Blocks (Eco-frames) - These blocks are designed for medium to small water flow conditions and soil erosion control in interlocking paving systems. The interlocking soil-retaining blocks, with their unique interlocking design, provide excellent overall stability under the action of water flow. The high-porosity, permeable, flexible surface reduces flow velocity, lowers fluid pressure, and enhances drainage capabilities. The openings not only facilitate water infiltration and drainage but also serve to increase the surface area and beautify the environment.
