As Turkey enters winter, heavier rainfall leaves buildings vulnerable; inadequate waterproofing turns minor leaks into major structural damage and economic losses. Nükhet Tercan Yıldırım, Sales & Marketing Director for Bituminous Membranes at Ravago Building Solutions, warns that proper pre-winter waterproofing extends a building’s lifespan and prevents costly repairs. Roughly 35% of homes in Turkey have insufficient waterproofing; even small leaks can evolve into structural damage over time. With increasing rainfall and sudden climate shifts, preventive waterproofing is a necessity.
35% of Homes Lack Adequate Waterproofing
In buildings without waterproofing, corrosion of steel reinforcement gradually undermines load-bearing capacity. Unprotected concrete elements deteriorate due to water and moisture ingress, mold develops, energy efficiency drops, and repair costs rise. Ahead of winter, roofs, terraces, balconies, parapets, and rainwater drainage details should be inspected thoroughly. Past “minor” leaks should not be ignored. Membranes must suit the building use and climate; whether bituminous or liquid polyurethane, correct material choice and quality workmanship are both critical.
A Critical Investment for Long-Lived Buildings
Typical penetration points—chimneys, ventilation outlets, and balcony junctions—are the easiest water entry routes; correct flashing and detailing significantly reduce risk. Downpipes and drains must be sized for rising rainfall intensity. On terraces and roofs, slope and drainage should prevent ponding, which shortens membrane life and accelerates leaks. Plan waterproofing with thermal insulation to boost energy efficiency and prevent moisture and mold. After installation, maintain regularly: keep gutters and outlets clean and inspect membranes for cracks. In critical zones, acoustic or electronic leak detection can lower repair costs and improve safety. Investing in proper pre-winter waterproofing costs far less than future remediation and is essential for building safety and longevity.
