BIM Sydney: Top Provider of Waterproofing NSW
Our team is not just a local, Australian remedial construction company; we’re the premier providers of professional waterproofing services throughout Sydney.
Risk mitigation for peace of mind
Subpar waterproofing can expose your project or building to damage and defects, cause construction delays, and result in legal liability. With BIM Sydney, we provide complete peace of mind with our technical, specialist waterproofing services backed by our warranties and insurance coverage.
Complete compliance with critical regulation
Many project managers may not be aware of the critical nature of not just protecting their asset but ensuring DBPA compliance for both new building construction and remedial work on existing infrastructure. Our team is knowledgeable in applying the complex legislation of the Design and Building Practitioners Act (DBPA) and ensuring the building under your watch is completely compliant.
Reliability and transparency at our core

When you’re on a tight project deadline or require urgent remedial property services, keeping on schedule and under budget isn’t a luxury – it’s a necessity. BIM Sydney’s reputation for keeping to budgets and timelines precedes us and we will do the same for you.
How Our Waterproofers in Sydney Can Help You
BIM Sydney is Sydney’s top remedial waterproofing company. We’re fully licensed. We’re a Master Builder certified waterproofer. And we’re experts in structural and non-structural remedial works for commercial, multi-residential and industrial properties.
Our residential and commercial waterproofing services are both comprehensive and customised to suit your needs:
Roof Waterproofing
Our waterproofing solutions for roofs include the application of a waterproof membrane, such as bitumen, EPDM rubber, or PVC. These can be installed under the roof’s surface materials which - alongside metal flashing around areas of roof penetrations, sealants along seams and joints, and proper slope and drainage systems (such as gutters and downpours) - ensures effective waterproofing.
Basements
Basements are highly susceptible to water infiltration. That’s why ensuring an effective drainage system alongside waterproof sealants or coatings to the interior walls is critical. Our team is also able to provide exterior wall coatings and crack injections to prevent further infiltration and install a sump pump system to remove accumulated water.
Window and wall waterproofing
In some instances, window waterproofing is as simple as proper flashing installation. In other applications we may apply caulking around the edges of the window frames and sealants between the window and wall for extra resistance. Our exterior wall coatings are highly weather-resistant to ensure long term durability and resistance to rain, moisture, dew and water exposure.
Building foundation waterproofing
We conduct onsite assessments to ensure a waterproofing solution for your building’s foundation that is as complex and customised as necessary. From waterproofing coatings and drainage system to grading around the foundation and sealants for internal walls, our team can and has done them all.
Bathroom and kitchen waterproofing
Our internal waterproofing services includes under-tile membranes, effective grading, sealant and caulking applications, installation of water-resistant material and efficient ventilation to reduce moisture build-up and damage.
Balcony waterproofing
The BIM Sydney teams are experts in balcony waterproofing services. We use a range of techniques, such as waterproof membranes, gentle sloping, drainage solutions, and sealants and flashing to ensure your balcony reminds protected, water-resistant and fully DBPA compliant
