Basements are the parts of a building that come into contact with underground moisture the most. Without proper protection, water can seep through the foundation, leading to structural damage. Especially in coastal towns like Çeşme or Alaçatı, this risk is higher due to high groundwater levels. The Most Common Mistake in Villa Renovations: In our experience at Küresel İnşaat, many full villa renovations overlook the basement. Often, there's no proper waterproofing, or it’s done superficially. This leads to bad odors, dampness, and expensive repairs in the future. How Basement Waterproofing Is Done: Exterior Waterproofing: Bitumen-based coating on outer foundation walls, followed by drainage and protective sheets. Interior Waterproofing: If the exterior is inaccessible, crystalline coatings are applied from inside. Drainage Systems: Excess water around the foundation is redirected away from the structure. Advice for Villa Owners: Cosmetic updates are important, but structural protection comes first. Without a dry and protected base, any surface renovation will be temporary. Conclusion: With professional waterproofing, buildings remain strong and healthy for decades. At Küresel İnşaat, we prioritize foundation waterproofing in every villa renovation project we carry out in the Çeşme region.
