  Reuse handrail(1)

  This is a method for repairing existing bridge railings to a like-new condition. The existing railings are taken from the site to the factory, where painting and plating are removed, damaged areas are repaired, and then they are re-plated and re-painted before being installed back on site. This method allows for corrosion protection of the interior of the railings, which cannot be achieved with on-site painting. The cost can be reduced to about half compared to new delivery, making it an environmentally friendly method.

  Special circular waterway(2)

  The drainage ditches, known as "full surface drainage type" and "slit type," efficiently drain surface water and originated from this product. Due to its structure that absorbs surface water seamlessly across the entire area, it prevents the formation of puddles and overflow to private land, significantly reducing the burden on the surrounding environment during events like sudden heavy rain. The slit width is set appropriately, and it is equipped with a grating cover, making maintenance very easy. Additionally, it can pick up items dropped by pedestrians, providing great peace of mind in emergencies. We offer a wide variety of types adapted to all situations, including vertical and entry types, cross types, and urban types that combine circular channels with boundary blocks fixed by bolts. All types are compatible with the increasingly mainstream "permeable pavement" across the country. Rainwater that has permeated the pavement is drained through unique collection holes provided on the product's side. Furthermore, during heavy rain, it captures both the rainwater that has permeated the permeable pavement and the overflow from surface drainage, ensuring smooth drainage and protecting the surrounding environment.

  Fabric formwork method(1)

  Fabric formwork, also known as fabric-forming method or concrete mat method, uses high-strength synthetic fibers. It is a technique where concrete is injected and cured on-site into fabric-forming mats that are manufactured in a factory based on design drawings. Compared to traditional cast-in-place concrete or precast block installation, this method allows for construction by a smaller team in a shorter time frame. Since underwater construction is possible, it eliminates the need for switching work and water-stopping work, resulting in shortened construction periods and enhanced cost-effectiveness. It adapts well to complex slopes with varying gradients, achieving uniform thickness. Due to pressurized injection with a pump, it can cover a wide area at once, regardless of slope or flat areas. The fabric-forming mats are lightweight, allowing for safe construction and easy transportation and storage. The water-cement ratio significantly decreases, leading to particularly high initial strength and a reduced curing period. We offer a wide range of options tailored to usage conditions, including filter point type, no-filter type, and greening type.

  3D Geocell Method Geoweb(1)

  It is applicable from slope protection, vegetation retaining walls, river and waterway embankments to subgrade and bearing capacity reinforcement works. The GeoWeb is a geocell product made by high-frequency welding high-density polyethylene sheets in a staggered pattern, which forms a three-dimensional honeycomb structure when deployed. By filling the cells with materials such as excavated soil or crushed stone, it creates a strong structure. The GeoWeb demonstrates effectiveness in various applications such as slope protection, retaining walls, river embankments, and improving subgrade bearing capacity, and its use as an environmentally friendly construction method is currently expanding. The GeoWeb is lightweight and compact, making it convenient for storage and easy to transport to the site. It can be deployed on gently sloping surfaces and used as slope protection material after being secured with anchor pins and covered with soil. Additionally, it can be used as a retaining wall simply by stacking it in a stepped manner on steep cut slopes. Because the material is high-density polyethylene, which is durable and flexible, it can be constructed to fit the shape of the site. If local seed-containing excavated soil is filled into the cells, greening with native species can be achieved. When installed as a layered retaining wall, seeds can be carried into the pockets, allowing for greening with native species.
