Overland Flood Damage in Woy Woy Garage & Covered Patio – Rapid Flood Restoration Matters

At this Woy Woy home, overland floodwater caused by an intense storm event impacted both the garage and enclosed patio, leaving clear signs of contamination and elevated moisture throughout the affected areas.

Wet & Contaminated Patio Floor Area Affected by Flooding

Incident Overview

Following an overland flood event, water entered the garage and covered patio, leaving a visible tideline approximately 500–1000 mm above ground level. The water category was identified as CATEGORY 3, meaning it requires thorough sanitation and cleaning to ensure all contamination is removed.

During our inspection, we confirmed:

• Clear tidelines around the perimeter of the garage and covered patio

• Visible impact to some contents within the affected areas

• Elevated moisture levels in the lower sections of the fibre cement wall between the garage and patio

• A visibly wet paved floor within the covered patio, indicating ongoing moisture presence

Based on the nature of the water ingress, this type of damage is typically considered category three water, requiring careful handling and decontamination procedures.

Our Response and Restoration Process

Overland floodwater can carry contaminants that pose potential health risks. To address this, our team implemented a structured response:

✔ Site Decontamination

The entire affected area was thoroughly decontaminated to reduce health concerns associated with flood contamination.

✔ Controlled Drying Setup

To stabilise moisture conditions and support effective drying, we installed:

• Air movers

• Dehumidifier

Drying efforts were focused on the covered patio area where moisture levels remained elevated.

Why Proper Flood Response Is Critical

Even after water recedes, moisture can remain trapped within walls, flooring, and structural materials. Without proper decontamination and controlled drying:

• Moisture can linger within building materials

• Odours may develop

• Health risks may increase

• Further deterioration can occur

Prompt action helps stabilise the environment and prepares the property for monitoring and any necessary future repairs.

The Result

With decontamination completed and drying equipment in place, the garage and covered patio were now ready for safe use by inhabitants.

This structured approach ensures the affected areas are managed safely following a flood event.
