Waterproofing +
Custom Solutions
80%
of building defects are linked to water ingress.
2-5
Most waterproofing failures occur within the first 2–5 years due to poor design or installation.
5-10x
Remediation costs can be 5–10x higher than getting waterproofing right the first time.
Waterproofing is not a standalone trade or simply a product selection; it is a fully integrated system that must be designed, sequenced, executed, and aligned with the broader construction process.
​
At tekDB, we approach waterproofing as a delivery-driven discipline. Every system is tailored to the specific conditions of the project — including substrate type, environmental exposure, structural movement, material compatibility, and curing requirements.
​
From internal wet areas to complex external and below-ground environments, we engineer solutions that perform as part of the overall build — not just at the surface.
Services
Precision waterproofing for bathrooms, laundries, and wet areas—designed to perform under daily use.
We ensure every junction, from floors to walls, is fully sealed to prevent moisture ingress, mould growth, and long-term structural damage.Tailored waterproofing system design based on site-specific conditions, usage, and performance requirements.
We develop complete, compatible systems—not just product selections—ensuring compliance, durability, and long-term quality.Expert waterproofing systems designed for balconies, terraces, rooftops, and exposed environments.
We protect structures from water penetration by managing drainage, movement, and environmental exposure—eliminating leaks and downstream damage.Flexible sealing solutions for critical junctions and service penetrations.
We maintain a continuous waterproof barrier while allowing for structural movement—preventing failure at high-risk points.Waterproofing for soil-contact structures exposed to constant moisture and pressure.
We prevent water migration, root intrusion, and structural deterioration—protecting surrounding building elements over time.Specialist systems for high-moisture and immersion-prone environments.
We ensure long-term system performance under continuous water exposure, maintaining integrity in demanding conditions.Correcting levels and drainage to ensure water flows as intended.
We establish proper falls and surface conditions—preventing ponding, premature failure, and compromised system performance.High-performance systems designed for areas subject to foot traffic and direct exposure.
We deliver durable, wear-resistant finishes that maintain waterproofing integrity while withstanding daily use and environmental stress.
Approach
Waterproofing design involves analysing substrates, moisture content, and structural movement, selecting compatible products and systems, coordinating sequencing with other trades, and ensuring correct application methods, thicknesses, and curing conditions are achieved. Every detail — from joints and penetrations to falls and drainage — is considered as part of the overall system.
​
The result is a compliant, reliable, and durable system built to perform.
A properly designed and executed waterproofing system provides long-term protection, reduces risk, and eliminates the need for costly rework. It ensures compliance, protects structural integrity, and delivers confidence at handover.
​
More importantly, it removes uncertainty — replacing reactive fixes with engineered, predictable outcomes.
Waterproofing requires more than product application—it demands a clear understanding of construction, materials, substrates, trade requirements, and system compatibility.
​
Each project is assessed individually to ensure the correct system is specified for the conditions, environmental exposure, and performance requirements—delivering efficient installation and long-term results and protection.
Waterproofing work in Australia must comply with the NCC and relevant Australian standards and can only be done by qualified and licensed contractors. In Queensland (QLD), this requires a current QBCC license.
​
Licensed professionals ensure all works meet these requirements—protecting the building, maintaining compliance, and reducing risk of defects and non-conforming work.
Insurance providers require waterproofing work to be carried out by licensed contractors. Non-compliant or undocumented work can void coverage in the event of water damage—leaving owners, builders and contractors exposed to significant repair costs and liability.
Waterproofing should always be supported by clear and comprehensive documentation.
​
Compliant records, product specifications, and completion documentation provide a verified record of works—ensuring transparency at handover and ongoing protection into the future.
Warranty assurance relies on more than product coverage alone.
Long-term performance depends on compliant installation, verified detailing, system compatibility, and documented quality control throughout construction.
In Queensland, requirements such as the Form 2 Seller Disclosure place greater importance on correctly licensed and documented building conditions and waterproofing to help protect property value and reduces risk during sale—ensuring the work is compliant, traceable, and defensible.
