Silent Damage Risk Caused by Surface Water in Çatalköy

In the upper parts of Çatalköy, close to the Beşparmak mountain range, rainwater does not move in a straight or predictable path.

Instead of being absorbed into the soil, water often flows over the surface, changing direction as it moves downhill.

With increased construction activity in recent years, this natural behavior of surface water has turned into a risk that is difficult to notice but capable of causing long-term structural damage.

How Does Surface Water Turn Into Damage?

After periods of heavy rainfall, surface water:

• Hits garden and retaining walls

• Loses its natural drainage path

• Accumulates around the foundations of properties at lower elevations

This process is not sudden.
Damage rarely becomes visible during the rainfall itself. It typically appears days or even weeks later.

Most Common Observations in Çatalköy

Surface water–related damage in Çatalköy is most often observed as:

• Moisture forming inside walls

• Blistering or peeling paint and plaster

• Mold development

• Softening or deterioration of floor surfaces

These signs are frequently described as:

• “It appeared out of nowhere”

In reality, the cause is almost always:

• Earlier episodes of intense rainfall.

Why Is This Called “Silent Damage”?

Because this type of risk:

• Does not resemble flooding

• Creates no immediate alarm

• Does not demand urgent intervention

Yet over time, it penetrates the structure itself.

In Çatalköy, surface water–related damage is often discovered only after the process has already progressed.

Why Does This Risk Keep Repeating?

The underlying reasons are consistent:

• Water descending from the hillside always follows the same routes

• As development increases, water has fewer natural escape paths

As a result, the same streets, similar building types, and comparable elevation levels experience repeating damage patterns.
