For general contractors: concrete surface preparation subcontractor in the GTA
MIR is a concrete surface preparation subcontractor for general contractors in Toronto, the GTA and Durham Region: it shows up when scheduled and hands the floor over on time. On condo towers, retail podiums, office fit-outs and warehouses, the crew grinds, patches and pours to the tolerance on your drawings and leaves a written flatness report for the file.
MIR also works as a commercial concrete grinding contractor, as the floor prep contractor for epoxy and resinous flooring installers, and on warehouse racking and equipment areas. Warehouse floor leveling combines grinding, joint repair and self-leveling in one package.
For condo boards & property managers
MIR repairs parking garages, parkades and common areas for condominium corporations and property managers in Toronto, the GTA and Durham Region. Parkade work covers spalls, joints and trip edges; common-area floor leveling covers lobbies, corridors, storage rooms and amenity spaces. The insurance certificate is sent with the quote, and the crew works around residents and documents the job.
MIR also takes down trip hazards on walkways and garage decks before they become a claim, and can schedule condo parkade concrete repair as part of a reserve-fund project.
For retail landlords & tenant fit-outs
When a tenant moves out, the slab usually comes back covered in old adhesive, thinset and patch leveler. MIR grinds it off, patches the damage and pours self-leveling concrete, giving the next tenant a flat floor for their flooring installer — often the fastest way to get a unit back on the market.
Developers also bring MIR in as the condo floor leveling contractor for ground-floor retail and amenity spaces in new towers.
Paperwork included. Floors flat.

Yes. Every self-leveling pour is re-measured with the same rotary laser we set it with, and you receive a written flatness report. If your specification calls for FF/FL numbers to ASTM E1155, raise it at the quote stage so the testing method is agreed before the pour.
