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 lacking residual strength due to aging or corrosion, using conventional technology to extend their lifespan. Additionally, it can satisfy seismic performance requirements for structures such as unreinforced manholes that lack seismic resilience. This system is well-suited for manholes that have reduced residual strength, including: ▶ Manholes with cracks ▶ Manholes that have advanced corrosion ▶ Manholes requiring 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 were developed in our country after 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 wealth of experience in the field of sewer construction. We prioritize the safety of those working on-site and the improvement of work efficiency, and we conduct daily research to understand what is needed. Moving forward, we will continue to listen directly to the voices from the field, create products that are first and foremost for the site, and strive to be of service. We sincerely ask for your continued support and patronage.
