The terrace waterproofing renovation process at GATA Hospital was meticulously carried out by our dealer, CK Barmanlar Construction and Insulation Materials. During the application, our Bonus Premium and Bonus Premium Mineral-Surfaced (Arduaz) membranes were used, providing a durable, long-lasting, and reliable insulation solution required for healthcare facilities. As Bonus Yalıtım, we continue to deliver sustainable, value-adding solutions with our high quality standards not only in hospitals but across all construction projects.
Terraces are among the building surfaces most exposed to external weather conditions. Due to factors such as rain, snow, melting ice, high humidity, UV radiation, and sudden temperature fluctuations, complete and properly executed insulation in these areas is of critical importance. In cases of application errors or insufficient insulation, water may penetrate beneath surface coverings over time, leading to moisture accumulation, mold formation, and surface deterioration on walls and ceilings—problems that negatively affect both human health and structural durability. Proper terrace waterproofing prevents these risks, preserving both occupant comfort and the long-term performance of the building.
Insufficient terrace insulation may cause reinforced concrete structural elements to remain exposed to water for extended periods, leading to reinforcement corrosion and concrete cracking. Such structural deterioration not only shortens the service life of the building but also creates serious safety risks by weakening the load-bearing system. Especially in older buildings, issues such as water leakage, surface cracks, and moisture-related damage can be eliminated through timely waterproofing renovation. This helps prevent structural and aesthetic damage in lower floors while also reducing additional risks such as damage to building installations and infrastructure systems.
The importance of terrace waterproofing is significantly greater in healthcare facilities. In areas where high hygiene standards must be maintained—such as hospitals, laboratories, intensive care units, operating rooms, and imaging centers—even minor moisture problems can compromise sterility. Mold, bacteria, and microorganism formation; malfunction of sensitive medical equipment; deterioration of indoor air quality; and risks to patient safety may arise as critical consequences. Therefore, properly designed, durable, and continuously maintained terrace waterproofing systems are indispensable for ensuring uninterrupted operation in healthcare buildings.
The Bonus Premium Membrane products applied at GATA Hospital provided a qualified solution supporting both structural safety and hygiene standards thanks to their high durability and long-term performance. As Bonus Yalıtım, we continue to enhance project value through our quality-, safety-, and sustainability-focused products across all types of buildings, including healthcare facilities.
