Quadex’s QLS pipe lining system restores pipe via Spin Cast Geopolymer Pipe (SCGP) methods and processes. SCGP offers many advantages over traditional centrifugally cast cement pipe (CCCP). Quadex’s SCGP process restores metal and concrete pipes and tunnels of all types and shapes more quickly and with a superior corrosion resistant geopolymer compared to CCCP. Supplementary application methods include wet gunite and dry gunite processes. QLS Applicators can successfully restore severely deteriorated man entry concrete, brick, or corrugated metal storm and sewer pipes of all shapes, types and conditions, including elliptical and arched pipes. The QLS system utilizes Quadex’s GeoKrete, the industry’s most advanced geopolymer. GeoKrete may qualify for LEED credits as it is composed of mostly recycled (sustainable) materials yet offers the rehab industry’s leading corrosion resistant and physical properties.
