The Hidden Strength Behind Milano Apartments: Bonus Membran Proof EP 350 H
At Milano Apartments, a residential project located in Istanbul’s Bahçeşehir district with a total area of 12,000 m², 12,000 m² of Bonus Membran Proof EP 350 H was used to provide long-term protection for critical areas exposed to soil and moisture. Applied by Deira İnşaat in cooperation with our dealer Akor İzolasyon, the solution provides continuous waterproofing that helps preserve reinforced concrete durability, indoor comfort and the building’s long-term value.Although the effects of water on buildings often develop gradually, the consequences can be serious. Moisture penetrating concrete may increase the risk of reinforcement corrosion, while leakage, dampness, mold and surface deterioration can reduce comfort and lead to difficult and costly repairs. For this reason, the most effective approach is to control potential water pathways during the construction phase before problems occur.
Developed for foundation and single-sided retaining wall applications, Bonus Membran Proof EP 350 H delivers high performance with its elastomeric SBS-modified structure. Under concrete pressure and hydration heat, it fully adheres to fresh concrete, helping to limit voids between the membrane and reinforced concrete surface through which water could migrate. This supports localized containment of potential damage and strengthens the continuity of the waterproofing system.
Its polyester felt reinforcement contributes to mechanical strength, while its specially engineered structure maintains flexibility at low temperatures. High puncture resistance and strong joint performance enhance reliability at critical application points, while the possibility of injection repair in the event of localized leakage offers an additional advantage during maintenance.
Bonus Membran Proof EP 350 H also stands out in terms of application efficiency. Its single-layer application reduces the need for additional layers such as primer, protective concrete and geotextile felt, while self-adhesive joints support faster installation and improved on-site control. These advantages provide significant value in terms of time management and project efficiency, particularly across large application areas.
Bonus Membran Proof EP 350 H, used in the Milano Apartments project, is a strong example of this comprehensive approach to waterproofing. Bonus Insulation continues to provide high-performance solutions designed to protect both the present and the future of buildings.
