In 2019 a decision was made to modernize an area above the emergency room that was predominantly a pedestrian deck but also included planters and skylights. Key concerns included a definitive waterproofing need due to high value space below, minimal presence of odor during installation, decorative options for an acceptable finished appearance and the availability of concrete preparation options compatible with the finished system to afford the owner a single source warranty.

Sika conducted on site adhesion testing to verify that the proposed Sikalastic-641 Lo-VOC RoofPro system would not only address installation needs, but it did not present any significant odor concerns as this is a semi enclosed area. With respect to the finished appearance, several areas elected to utilize a custom colored aggregate with a Sika clear poly aspartic sealer to achieve the desired look. Beyond function and appearance, a significant cost savings verses competing systems was realized as well.
