The Project Coordinator of a Toronto University satellite campus located in Mississauga requested the help of ICC to install their exclusive waterproofing system in the Block A Mechanical Room.
The scope of work covered 6 stages, beginning with the mobilization/demobilization process, project management/project schedules, mechanical concrete preparation, the ICC cove system, and the ICC waterproofing system.
STAGE 1 – Mechanical preparation of concrete
ICC performed a comprehensive overhaul of the present concrete surface by employing an HTC 800 mechanical diamond grinder. This helped eliminate all oils, pollutants, and coatings, which was followed by a commercial vacuum system with HEPA filtration (PIC) to ensure minimal residual dust.
ICC advantage: Hand profiling along perimeter walls, drains, & mechanical eqpt.
STAGE 2 – Mitigation procedure
We introduced an additional cleaning process to make sure the concrete surface is fully clean. This included sweeping and vacuuming the profiled concrete substrate.
ICC advantage: Additional cleaning of substrate ensures increased bond strength.
STAGE 3 – Concrete rehabilitation
As part of the final preparation phase, ICC carried out various tasks including crack chase and fill, repairing delaminated concrete, profiling concrete, patching concrete, cleaning and filling control joints, as well as detail work around drains.
STAGE 4 – ICC hand-trowelled coving system
A unique cove system was installed by the ICC team around the machine pads and perimeter walls. This high-quality system was installed by hand at a 45-degree angle and serves the purpose of preventing any water infiltration in the area.
STAGE 5 – Waterproofing membrane installation
A 30-ml base coat made up of two parts containing a membrane with elastomeric properties was used. This coating is expandable and can resist new cracks in concrete slabs while also providing protection against water penetration.
STAGE 6 – Protective top coat
For the last step, a 20-ml layer of solid epoxy protective top coat was used, which consists of two parts. This top coat safeguards the base coat membrane, making the surface coating more long-lasting. ICC also offers anti-slip finishes as an option.
