SamBaek Construction is using Atlas Copco’s X28 Stage V portable air compressor to support slope reinforcement and seismic retrofitting at a residential construction site in the Gosan 2 District of Gwangju, Gyeonggi Province. The project, which began in May 2025, involves building retaining walls to stabilize steep terrain ahead of new housing development.
The X28 model offers a pressure range of 16–30 bar (232–435 psi), making it suitable for applications such as earth anchors, nailing, rock bolts, micropiling, shotcrete, and groundwater development. According to the contractor, this versatility has allowed the company to carry out multiple phases of slope reinforcement with a single unit.
SamBaek Construction previously relied on rental compressors, typically with a capacity of 17–21 bar (247–305 psi) and a flow rate of 900 cfm (25.5 m³/min). These units often struggled with the granite-rich terrain in the area. The company purchased the X28 earlier this year after working with rented Atlas Copco equipment on earlier projects.
The unit is designed with noise-reduction features and a Stage V compliant engine, which make it suitable for use in urban and residential zones where environmental and regulatory requirements are strict. Fuel efficiency is supported by an ECO mode that reduces consumption during idle periods, which can account for several hours each working day.
Atlas Copco Korea’s Portable Air Division and Power Technique Service teams provided on-site training to SamBaek Construction staff, covering fuel-saving functions such as ECO mode and AirXpert. The company expects these features to help reduce overall operating costs while maintaining the pressure and flow required for slope reinforcement and seismic retrofitting.
