A trusted partner in trenchless rehabilitation
for underground buried pipelines.

TLT has built a scientific and systematic management system across the entire process—from investigation and diagnosis of water and sewer pipelines to trenchless rehabilitation—based on differentiated construction methods and advanced technological capabilities.

Trenchless rehabilitation technology is driving a paradigm shift from conventional excavation methods to trenchless methods, contributing to reduced social costs, improved construction safety, and global carbon-reduction efforts. TLT will continue to lead this transformation and advance innovation in underground pipeline rehabilitation.

In addition, to present a new direction for aging pipeline rehabilitation projects that have long been overlooked due to incomplete workmanship and quality issues associated with excavation-based methods, we are realizing stable growth and development through continuous technology development and commercialization.
