Elevator pit repair at a high-rise apartment building near Lakefront Promenade Park in Mississauga turned out to be more complex than it had originally seemed.
A Hidden Issue
The pit was damp, but as our crew started chipping out the cold joint in preparation for repair, water started gushing out – moisture had built up over time.
If waterproofing had not been done (at that moment it looked like the issue was not serious – just some dampness), the water would have continued accumulating, putting additional pressure on the elevator pit wall. In the end, elevator equipment could have been damaged.
Before any waterproofing could be done, the accumulated water that was rushing out of the floor/wall corner had to be drained. After that, our crew did the necessary crack repair and patching before applying a polyurea-based waterproofing membrane.
This polyurea-based waterproofing membrane is ideal for applications that require a high level of protection against mechanical and aging issues, since it has been proven to withstand 30 years of freeze-thaw cycles.
