Keller constructs geotechnical solutions that are cost-effective despite the unique challenges for wastewater/sewage treatment, transport, and disposal projects.

Through our experience from previous projects, we can execute programs and create tailored solutions customized to your project’s needs, from shielding sewer and water lines to reinforcing existing and planned facilities. Combined Sewer Outfall (CSO) projects profit from our knowledge with deep tunnelling projects. We offer real-time monitoring and specialty grouting during tunnelling operations to avoid damage to adjacent structures.
