Speeding Up Slope Reinforcement with Atlas Copco’s X28 Portable Air Compressor

 

 

Slope reinforcement is a critical part of safe urban development – especially in mountainous regions like South Korea’s Gyeonggi Province. At a residential construction site in Gwangju, SamBaek Construction used Atlas Copco’s X28 portable air compressor to carry out micropiling for slope reinforcement and seismic retrofitting with greater speed, reliability, and compliance.

The project began in May 2025 and involves building retaining walls to stabilize steep terrain for future housing. In densely developed areas, earth retaining work is no longer just a preparatory step – it is a core process that directly impacts the safety and efficiency of the entire construction project.

SamBaek Construction had previously relied on rental compressors. After consistently seeing stable performance from Atlas Copco units on site, the company decided to make its first direct purchase through the Portable Air Division within the Power Technique Business Area at Atlas Copco Korea.

The X28 offers a broad pressure range of 16-30 bar, making it suitable for a wide variety of applications including earth anchors, nailing, rock bolts, micropiling, shotcrete, and groundwater development. This flexibility allows SamBaek Construction to use a single compressor across multiple phases of slope reinforcement and seismic retrofitting.

Urban development sites demand equipment that minimizes noise. The X28’s low noise make it ideal for use in residential zones, where regulatory compliance and community impact are key concerns.

In slope reinforcement projects, compressors often run idle during casing and pipe welding steps. For SamBaek Construction, this idle time accounts for nearly 3 out of 8 working hours per day, leading to unnecessary fuel consumption. the ECO mode feature helps reduce fuel usage during unloaded operation.
