Dealing with water ingress in basements and carparks of strata buildings is a complex task requiring a meticulous and strategic approach. At Stormwater Sydney, we specialise in providing tailored solutions to these challenges, as showcased in our projects at a Warrawee Strata Complex and Hunters Hill Townhouse Development. Let’s explore these case studies, highlighting our unique approach that includes initial visual inspections, active testing, and solving issues systematically to minimise costs.

Case Study 1: Warrawee Strata Complex

At the Warrawee Strata Complex, we encountered significant basement flooding issues due to a malfunctioning pump-out system and compliance shortcomings in the stormwater system.


Our approach saw the team begin with an initial visual inspection to understand the extent of the issue.  This was followed by active testing which involved examining behind the walls and other hidden areasto accurately diagnose the problem.  We then undertook a step-by-step solution implementation. We tackled each issue individually, starting with high-pressure cleaning of pipes and moving on to cleaning and maintaining the basement water tank and pump-out system.

This strategic approach not only resolved the flooding but also enhanced the overall compliance and efficiency of the stormwater system.

Case Study 2: Hunters Hill Townhouse Development

The Hunters Hill project presented a unique challenge with water build-up behind the retaining walls in the underground car park. Our approach included:

  • Initial Visual Inspection and Active Testing: To understand the water dynamics and structural aspects contributing to the build-up.



  • Comprehensive Solution: Installation of new stormwater lines with drainage/access pits, integrated into the retaining wall for future maintenance and effective drainage, accompanied by extensive cleaning and repair work.


This methodical and thorough approach ensured a long-term resolution to the water ingress problem.

Our Comprehensive Approach:

At Stormwater Sydney, our strategy in addressing basement and carpark water ingress includes:

  • Initial Visual Inspection: To assess the situation and plan the course of action.
  • Active Testing: Investigating behind walls and other areas to understand the root cause.
  • Systematic Problem Solving: Addressing each issue one at a time, focusing on minimising costs while ensuring effective solutions.
  • Long-Term Solutions: Our goal is not just to fix the immediate problem but to provide sustainable solutions that prevent future occurrences.

Tackling water ingress in strata buildings requires expertise, strategic planning, and a focus on long-term solutions. Stormwater Sydney’s approach of initial inspection, active testing, and systematic problem solving ensures that we not only fix the current issues efficiently but also safeguard the property against future problems.
