ACEFormer™ geotextile mattress is a dual-layer structured fabric, capable of being filled with high-strength fine aggregate concrete or cement mortar to function as a protective lining system. Its merits include adaptability to various terrains, simple and rapid construction, excellent integrity once installed, and strong resistance to erosion. The geotextile mattress can be installed on land, underwater, or steep slopes for applications such as riverbank revetment, channel protection, underwater lining, and pipeline protection. Customized to meet local conditions, the geotextile mattress offers superb flexibility and presents significant advantages over traditional concrete solutions due to its ability to conform excellently to diverse application environments. The following products are covered in this EPD: V-Type, F-Type, L-Type, T-Type, U-Type and P-Type. PET yarn and PP yarn are the raw materials used in the production of ACEFormer™. Prior to production, the original yarn must be twisted into processed yarn, an operation carried out by external partners. Once the twisting process is complete, the yarn is trucked back to the Gold-Joint factory for further processing. Post the warping process, the processed yarn can be fed into the production line for weaving geotextile mattresses. Weaving is a fabric production method 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 specific design of the textile structure, both single-layer and double-layer fabrics can be produced, with their sizes adjustable based on application requirements. After weaving, the fabric is rolled onto beams and sent to the internal processing department for sewing operations. Since geotextile mattresses are custom-made products, the processing is done according to the specifications, forms, sizes, and accessories required by the order. Before the sewing process begins, the fabric is inspected for defects. The fabric is then cut and sewn according to order requirements, and necessary parts (e.g., handler loops, zippers) are sewn and affixed to the product. Upon completion, quality control personnel measure the final product's dimensions and count the number of accessories using a production checklist. After careful inspection of the sewing areas, the product is folded and packaged. The construction process of ACEFormer™ can be divided into the following parts: Preparation of the site; Placement of ACEFormer™; Anchorage process; Filling of the panels with flowable concrete/mortar.

ACEFormer™ geotextile mattresses are specialized for hydraulic and erosion control uses. Notably, they're employed in riverbank stabilization projects, where they are studied for their ability to prevent soil erosion, especially with the rise in flood events. Their utility in preserving both natural habitats and human-made structures near coastlines is under scrutiny. ACEFormer™ also find use in scour prevention. They're applied at the bases of structures like piers and embankments, where water-induced erosion could threaten stability. Engineers are assessing their short and long-term performance in these contexts. Further versatility is seen in applications like slope stabilization and constructing revetments. Their adaptability suits them for projects with diverse demands.
