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.

STRATA AND COMMERCIAL WATERPROOFING EXPERTS
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.
