Situation:

Located in the heart of Federal Hill in Baltimore’s Inner Harbor, The Ritz Carlton Residences epitomize luxury and quality. The intricate design of the balconies offering a waterline view required 3” keystone caps that, unfortunately, created dams. These dams caused water pooling. Combined with a lack of waterproofing on the concrete balconies, the pooling put the exterior surfaces of these prestigious residences at risk for moisture damage and stagnate water pooling.

Challenges:

• Building balconies were holding standing water because of keystone caps at the balcony’s edge
• Ponding water became stagnate and eventually flowed back into the residences

Solution:

ARDEX ARDICOAT™ PLUS was applied to waterproof the balconies. ARDEX ARDICOAT is an easy-to-apply waterproof coating for all types of concrete and masonry. It can be troweled or sprayed on horizontal or vertical surfaces on all grade levels. A gutter was created by removing a small section of the balcony keystone. In addition, gaps were filled at the balcony edges and ARDEX ERM™ Exterior Ramp Mortar was used to repair the fascia. ARDEX ERM has a corrosion inhibitor built-in to protect reinforcing steel which is needed for long-term protection for outdoor balconies. This combination of ARDEX Engineered Concrete Repair Systems products was the perfect, long-term solution for The Ritz-Carlton Residences.
