Quadex was founded in 1991 and is one of the most respected names in the protective coatings and linings sector of the wastewater rehabilitation industry.

We began by manufacturing a complete line of cementitious products and continue to refine our products and develop new ones that keep Quadex at the forefront of the infrastructure protection and restoration industry. Our staff and team of Certified Applicators are dedicated to providing only the highest quality products and equipment used to rehabilitate old or damaged wastewater structures.

Quadex products and equipment, and the Certified Applicators that use them, work to protect and restore the structural integrity of water related structures including, manholes, wetwells, pumping stations, headworks and other severe duty wastewater structures.Quadex products are formulated and designed with the most advanced technology and are proven with over 20 years of successful installations. Our products offer unmatched structural and flexural strength, permeability, application thickness and quick return-to-service workability. Our specialized lining products provide a permanent seal against corrosion, infiltration and exfiltration, and support an installation life of 50-100 years. To ensure the performance of each product, we verify the results of our in-house studies through extensive independent laboratory American Society for Testing and Materials (ASTM) procedures.
