Waterproofing Services
Accurate Diagnosis, Certified Application, Long-Term Protection

​

At Trade Constructions, we are not your typical waterproofing company. Our leak detection specialists are licensed builders with advanced expertise in water ingress identification and rectification. With years of experience across inspections, diagnostics and remediation, we understand both the symptoms and the root causes of water-related building failures.

​

We go beyond surface treatments. Our approach to waterproofing is grounded in precision, compliance and performance. Each project is backed by industry-leading knowledge, ensuring that the solution provided is technically sound, long-lasting and fit for purpose.

​

Many of our waterproofing systems are covered by a 10-year warranty, giving our clients peace of mind that the job has been done right the first time.

​

Advanced Leak Detection and Rectification

​

Water issues can be elusive. That’s why our team uses detailed testing methods, not guesswork. Our investigations involve moisture mapping, pressure testing, thermal imaging and flood testing as needed, depending on the construction type and site conditions. This ensures we identify the true source of water ingress and apply the correct rectification strategy for a permanent solution.

​

Our highly trained waterproofing team has extensive experience working on both residential and commercial buildings, including high-rise and strata-managed properties.

​

Strata and Commercial Expertise

​

Strata and commercial waterproofing projects require more than just technical skill. They require planning, coordination and a builder who can manage works within shared environments, where multiple stakeholders are often involved.

​

At Trade Constructions, we are equipped to manage these complexities. We handle large-scale remediation and waterproofing works with clear communication, documentation and minimal disruption to occupants. This sector has become a core part of our business and reflects our ability to deliver in politically sensitive, logistically demanding environments.
