1. Introduction to Hiring a Specialist Waterproofing Consultant

Water ingress in strata buildings can lead to significant structural issues and costly repairs. The role of a specialist waterproofing consultant is crucial in diagnosing and rectifying these problems. Strata committees in Australia face the challenge of selecting a competent consultant who can effectively address and prevent water ingress issues. This article provides comprehensive guidance on what to consider when hiring a building waterproofing consultant.

2. Understanding Water Ingress

Before seeking a consultant, it's important to understand water ingress. Water ingress refers to the unintended entry of water into a building, often through roofs, walls, or basements. It can lead to mould growth, structural damage, and degradation of building materials. In strata properties, where multiple units share common areas, the impact of water ingress can be extensive, affecting numerous residents.

3. The Role of a Waterproofing Consultant

A waterproofing consultant specialises in diagnosing and solving water ingress issues. They assess the building's condition, identify water ingress sources, and recommend effective remediation strategies. Their expertise is invaluable for strata committees that need to maintain their properties and protect their investments.

4. Essential Qualifications for a Waterproofing Consultant

When selecting a consultant, consider their qualifications. They should also have relevant experience specifically with strata properties. Knowledge of Australian building codes and standards is crucial for ensuring compliance and effective solutions.

5. Technical Expertise and Knowledge

A good consultant should be well-versed in both old and new waterproofing technologies and materials. They should understand the unique challenges presented by the Australian climate and local environmental factors.

6. Analysing Water Ingress Defects

A thorough analysis of water ingress defects is essential. The consultant should use advanced diagnostic tools where necessary and techniques to accurately identify the sources of water ingress. This may involve tools such as ultrasonic gauges and infrared imaging. The use of drones for inspection and image capture of defects and issues at higher elevations can provide significant time and cost savings. Skills in systematic testing, forensic deconstruction and investigation are also required.

7. Developing a Waterproofing Strategy

After identifying the issues, the consultant should develop a tailored waterproofing strategy. This plan must consider the specific needs of the building, taking into account its design, age, and the severity of the water ingress.

8. Communication and Reporting Skills

Clear communication is key. The consultant should provide detailed reports, explain their findings, and offer clear recommendations. They should be able to explain complex technical issues in simple terms for the strata committee to make informed decisions.

9. Project Management Skills

Managing a waterproofing project involves coordinating with various trades, adhering to timelines, and managing budgets. A consultant with strong project management skills can ensure the project runs smoothly and efficiently.

10. Case Studies and References

Look for consultants with a track record of successful projects. Review case studies and ask for references to gauge their expertise and reliability.

11. Cost Considerations

Understand the cost implications of the waterproofing project. A good consultant will provide transparent pricing and help the committee balance quality with budget constraints.

12. Legal Compliance and Liability

Ensure that the consultant is compliant with all relevant Australian legislation and carries appropriate insurance such as Public Liability, Workers' Compensation and Professional Indemnity insurance. This protects the Strata Committee from potential liabilities.

13. Ongoing Maintenance and Support

Post-rectification support is crucial. The consultant should offer guidance on maintaining the waterproofing system and schedule regular check-ups to prevent future issues.

14. The Selection Process

Selecting the right consultant involves a careful vetting process. Consider conducting interviews, checking credentials, and comparing proposals from multiple consultants.

15. Strata Committee's Role in the Waterproofing Process

The strata committee should be actively involved in the waterproofing process. This includes overseeing the project, facilitating communication, and ensuring that residents are informed and prepared for any disruptions.

16. Future-Proofing Strata Buildings

Consider long-term waterproofing strategies that account for climate change and evolving environmental conditions. This proactive approach can save costs and hassle in the future.
