From subway stations to swimming pools, from bridges to buildings, and in foundations, critical infrastructure, and many other applications around the world, explore our always expanding list of Project Profiles to learn how Xypex Crystalline Technology waterproofs, protects and repairs concrete.
Delhi Metro Rail Corporation (DMRC) Phase III & Phase IV
Due to the success of the Xypex surface-applied and repair system in various projects, the Delhi Metro engineering team consulted Xypex to provide a waterproofing solution for phase III. The engineering team specified Xypex Admix C-2000 NF and Xypex Concentrate for the waterproofing of phase III underground stations in conjunction with spray applied membranes on the rooftop slab.
Toronto Transit Station Underpass
The Metrolinx engineering and Ellis Don teams chose Xypex for this project. “They evaluated traditional membrane waterproofing vs. Xypex,” Zaniewski said. Xypex admixture was selected due to the time saved by eliminating the labour-intensive membrane application to concrete below the water table. “The engineering team realized the economics of Xypex Admix, not only in construction scheduling but in performance.
Quarles Water Treatment Plant
In 2012, after 58 years of service, Plant No. 1 showed the effects of age from decades of service. The concrete in Plant No. 1 suffered deterioration, including exposed rebar, exposed aggregate, loss of surface paste and spalling. CCMWA called on water engineering experts Hazen and Sawyer to study its operation and make a recommendation for Plant No. 1. The team recommended replacing the original plant with a new plant with a capacity of 33 mgd that could be expanded to 66 mgd in the future.
Yankee Lake Regional Wastewater Treatment Facility
To start repair works, the general contractor, Crom Corporation, first blasted the old concrete surfaces with a 3,000-psi pressure washer to remove the old epoxy coating, then disinfected the substrate to remove bacteria present on the surface. After these steps, cracks and joints were repaired with Xypex Patch’n Plug and Concentrate.
