| Use advice for data set | The results table shown on the ÖKOBAUDAT refers to the product ACEMat™ R with the specific mass of 0.27 kg/m^2. |
| Technical purpose of product or process | ACEMat™, woven into mesh structures with rectangular pyramid patterns, has shown effectiveness in erosion control and channel protection. This TRM is especially useful in civil engineering for stabilizing slopes. Rain impact can dislodge topsoil, exposing roots and foundations, thus destabilizing slopes. ACEMat™ not only enhances slope filtration and stabilization but also encourages vegetation growth, offering robust soil and rock slope erosion resistance. In environmental restoration, ACEMat™'s ability to promote vegetation and retain soil makes it a key tool, especially given rising concerns over land degradation. Additionally, these mats are used in constructing channels and swales where they reduce erosion and support vegetation. Research is underway to evaluate their potential in optimizing hydraulic efficiency and maintaining channel bed integrity. Their relevance is growing in stormwater management, as they could mitigate runoff and facilitate water infiltration, contributing to sustainable practices, particularly as climate-related challenges like increased precipitation become more common. |

| Technology description including background system | ACEMat™ is a Turf Reinforcement Mat (TRM) made of high-strength polypropylene monofilament. With its stable and thick three-dimensional woven structures, ACEMat™ is highly effective in controlling severe erosion problems in steep slopes, barren areas, riverbanks, channels, and areas with heavy rainfall. It interlocks with soil to create a solid base, dissipating run-off and stream erosive forces while protecting the soil surface from water splash and wash. Furthermore, it retains seeds and supports plants when vegetation is required, providing exceptional erosion control and enhanced vegetation performance. The primary material for ACEMat™, PP monofilament, is produced by thoroughly mixing and stirring various plastic pellets, followed by extrusion and stretching processes. After the PP monofilament undergoes the arranging process, it is ready to be fed into the production line for weaving ACEMat™. Weaving is a method of fabric production where two distinct sets of yarn interlace at right angles, forming a longitudinal warp direction (machine direction) and a transversal weft direction (cross-machine direction). Through careful textile design, ACEMat™ displays a rectangular arrangement on its surface. After the fabric undergoes heat shrinking, the yarn forms a three-dimensional rectangular pyramid-like structure. Upon passing visual inspection, the fabric is cut to the required lengths, rolled onto paper tubes for packaging, and then stored in the warehouse. The construction process for the turf reinforcement mat, ACEMat™, can be categorized into the following stages: Preparation of the site; Placement of ACEMat™; Execution of anchorage process; Implementation of hydroseeding process. |
