When it comes to helping our clients make the most efficient use of landfill space while meeting stringent regulations, CTI’s innovation is unparalleled in the solid waste industry.   In fact, CTI is proud to hold a patent for septage bioreactor landfill technology and to have provided design engineering and field services for the first septage bioreactor landfill in the country.  We work hard to make sure that our solutions extend the life of the site, cut operating costs, and reduce regulatory complications.

CTI has extensive experience in design, permitting, construction, operation, monitoring and reporting for both traditional and “wet” landfill cells, including enhanced leachate recirculation and bioreactor projects.  Our areas of specialty in solid waste services include: siting and critical-path evaluation; hydrogeological investigation; design, permitting and licensing; construction; certification; and operation and maintenance, including landfill closure and post-closure care.    

We are also proud to offer a field services team seasoned in landfill construction management and construction quality assurance (CQA) monitoring and certification.  Our field services team excels in the areas of:  soils; geosynthetics; leachate removal and gas collection systems and controls; retaining and cut-off wall systems; monitoring of landfill gas, leachate, and surface/groundwater; regulatory reporting; and other general site features including roads and infrastructure systems.

And if your project requires more than just engineering or a qualified field technician, we’ve got you covered there too.  CTI is also the proud owner and operator of a fully equipped soil and material testing laboratory.   Our lab can provide the testing services you need for permitting, design, and construction compliance monitoring.  Our primary services include:  soils testing for classification; hydraulic conductivity for granular and cohesive soils; soil density/moisture (proctor) properties; and geomembrane seam testing.
