The hotel is located in Baltim coastal zone, directly exposed to aggressive rain and humid marine conditions. The system required extreme durability and watertightness for decades.
A multi-layer waterproofing system was designed and executed, combining polyurethane foam, acrylic protective coating, geotextile reinforcement, and advanced joint sealing. This ensured long-term resistance to heavy rainfall, salt-laden air, and structural movement.
