Project Overview

Residential Flood Protection Project

Flow Defence supplied and installed a self-activating flood barrier at the basement entry of a residential property in Ashburton VIC. The barrier was designed to help prevent water entering below-ground areas during heavy rainfall while also meeting Melbourne Water flood mitigation requirements.

Because the basement entry created a direct pathway into the lower level of the property, a dependable flood protection solution was needed to reduce the risk of water ingress and support compliance with the approved flood management requirements.

The Problem

Flood Risk at Basement Entry

Basement entry points are particularly vulnerable to flooding, as water can quickly flow into below-ground areas and accumulate inside the building. At this property, the basement access created a direct pathway for water to enter the lower level during heavy rainfall.

As part of the project, Melbourne Water required a flood mitigation solution to reduce the risk of water entering the building and to support compliance with local flood management requirements.

This posed a risk to:

Vehicles stored in the basement
Personal belongings and storage areas
Internal building finishes and services

Once water enters a basement, it can be difficult to remove and may result in ongoing damage if not properly managed.

The Solution

Self-Activating Flood Barrier Installation

Flow Defence installed a self-activating flood barrier system across the basement entry to provide site-specific residential flood protection. The barrier measured 0.4m high × 3.6m wide and was selected to suit the flood risk, basement layout and compliance requirements of the development.

This system was chosen because it:

self-activates as water rises
requires no manual deployment
helps protect a critical below-ground entry point
supports projects with flood mitigation and compliance requirements

It is well suited to residential properties with basement or underground parking areas where dependable flood protection is required.

The Outcome

Reliable Flood Protection for Below-Ground Residential Areas

The completed installation provides ongoing flood protection for the property while satisfying Melbourne Water flood mitigation requirements.

The installed barrier helps to:

reduce the risk of water entering the basement
protect vehicles, stored items and internal lower-level areas
help prevent water accumulation in below-ground spaces
support compliance with local authority requirements
provide a long-term flood protection solution for basement access areas exposed to stormwater runoff

The result is a practical and dependable system designed to help protect the property during heavy rainfall events.

How It Works

Self-Activating Flood Barrier at the Basement Entry

The flood barrier is installed across the basement entry and is designed to activate as water levels rise. This creates a physical barrier that helps prevent water flowing toward and entering the lower level of the building.

Because the system is self-activating, no manual deployment is required during a flood event. This makes it well suited to residential applications where reliable protection at a vulnerable basement entry is important.
