Watch as we hammer off loose concrete from rebar expansion, and patch with Mapei Planitop XS. It’s a long laborious process but necessary and so gratifying. The rebar expansion is a result of corrosion from salt that causes the steel to rust and blow off the concrete. These repairs are necessary to maintain structural integrity of the slab, and protect cars from falling debris
Gimli Manitoba: Concrete and membrane repair- Check out this Complicated Rooftop Waterproofing Repair made Easy….
Improper grading on this rooftop patio lead to water ponding and subsequent damage to the front facade on this multi family property.
First step was to remove existing membrane 40” from the front parapet wall across the entire width of the building- so the concrete could be re graded
Once removed we used Sika Quick 1000 to re slope the concrete to drain to the scuppers. This product allowed membrane to be re installed within 24 hours for fast turn around.
This process was completed in 5 days from start to finish.
