After the 30 magnitude earthquake that took place in İzmir on 2020 October 6.9, 88 100 units with XNUMX independent sections bina urgently destroyed. As a result of the damage assessments, it was determined that 3 buildings with 944 thousand 618 independent sections were heavily damaged, and 6 buildings with 617 thousand 660 independent sections were moderately damaged. This earthquake, "How solid is my house?" brought the question. What should new home buyers pay attention to? We researched for you…

After the 1999 earthquake in Gölcük, earthquake resistance, which is one of the most sought after criteria for home buyers, has become less questionable in recent years compared to the past. After the 30 magnitude earthquake that took place in İzmir on October 2020, 6.9 and caused pain to all of Turkey, “how strong are our houses?” came the question. The criteria we should pay attention to when buying a new house;

- Look into the basement of the building. If rutubeIf it is, it means that the waterproofing of the building is not well done. Corrosion of the carrier systems of buildings with poor insulation causes damage to the structure during a severe earthquake.

- During construction, prefer buildings produced with ready-mixed concrete technology. Do not prefer buildings built with concrete with less than C20 strength in buildings built in earthquake zones.

- The design of the building can also provide earthquake resistance. Design factors such as symmetrical dimensioning and the use of short columns can make the structure more resistant to earthquakes.

- Find out that column and curtain applications are carried out with the right methods. In order to learn the technical features, you can have the engineers examine the building you want to buy an apartment.

- Make sure that one third of the building is under the ground. Remember that the more floors there are under the ground, the more reliable the building is against earthquakes.

- Do not forget to review the floor survey report. Again, it should not be forgotten that not every building can be applied to every floor. The right building applied on the right ground is earthquake resistant.
- Do the buildings have an Energy Performance Certificate? Look. The Energy Identity Certificate, which is now a legal requirement, shows that the building is heat insulated. With fuel savings, your money is in your pocket.
