Supports inspection certificates No. 1 to 4 up to 10m! With a self-supporting manhole system, rehabilitation is possible without relying on the residual strength of existing manholes! Compatible with seismic levels 1 and 2.
The "SS Hole System" by Ibuild is a method that rehabilitates manholes with insufficient residual strength due to aging or corrosion, using conventional technology to extend their lifespan. Additionally, for manholes lacking seismic performance, such as unreinforced manholes, the SS Hole System alone can satisfy seismic performance requirements. It is suitable for manholes that have experienced a decrease in residual strength, such as: ▶ Manholes with cracks ▶ Manholes that have advanced corrosion ▶ Manholes that require seismic reinforcement ▶ Manholes with high hydrogen sulfide concentrations ▶ Manholes that cannot be replaced 《Construction Technology Review Certificate (Sewage) obtained March 18, 2021, No. 2021 Scope of application expanded: Manholes No. 1 to No. 4, up to a depth of 10m》

Company information
The infrastructure structures such as sewers, roads, bridges, and tunnels that have been developed in our country since the period of rapid economic growth are expected to rapidly deteriorate in the future, raising concerns about falling into dangerous conditions. It is necessary to strategically maintain and update the infrastructure that will age simultaneously. Our company has a strong track record in the field of sewer construction. We prioritize the safety and efficiency of those working on-site and conduct daily research to understand their needs. Moving forward, we will continue to listen directly to the voices from the field, create products that are focused on the site, and strive to be of service. We sincerely ask for your continued support and patronage.
