Westin Wall is a hotel and residential tower built around 2010 without Krystol Internal Membrane (KIM) in the original concrete. The development subsequently experienced significant cracking in the raft slab and ongoing water leakage.

Several rounds of repairs using grout and injection have been undertaken, but leakage reportedly continues. The interior parkade ramp is also reported to have inadequate detailing and to be subject to high hydrostatic pressure.

Krystol Leak Repair System is the identified solution for addressing the reported leakage at Westin Wall.
