Pacific Building Services offers expert waterproofing services in Sydney for homes, apartments, commercial buildings, and strata complexes. We operate across key areas including the Sydney CBD, Eastern Suburbs, Inner West, Northern Beaches, North Shore, Inner South, Upper North Shore, and Western Suburbs. Our licensed team delivers reliable and affordable waterproofing solutions to prevent water damage, mould, leaks, and costly repairs. All work is fully compliant with Australian standards and comes backed by warranty.
Whether you’re dealing with rising damp in a basement or leaks on a rooftop, our team has the right solution. We use advanced waterproofing membranes, coatings, and sealants for all surface types. Each project is tailored based on your property’s condition, layout, and exposure to moisture. We also offer remedial waterproofing for older or damaged buildings in need of restoration.
Basements are highly prone to moisture and rising damp. We use a combination of positive-side, negative-side, and cavity drainage methods to keep your basement dry. Our basement waterproofing services are ideal for residential homes, apartment blocks, and commercial basements in flood-prone areas.
Balconies and decks are exposed to Sydney’s changing weather. We apply flexible membranes and protective coatings to prevent leaks, tile damage, and concrete erosion. Our waterproofing systems are designed to extend the life of your outdoor living areas while maintaining safety and aesthetics.
Bathrooms are one of the most common sources of water damage. We deliver complete waterproofing for floors, walls, and corners to meet Australian Standard AS 3740. If you’re planning a bathroom renovation in Sydney, we ensure the waterproofing is done right from the start.
We provide roof waterproofing services in Sydney using liquid membranes, heat-applied sheets, and sealants. Our systems are compatible with tiled, concrete, and metal roofs. Roof waterproofing not only prevents leaks but also reduces future maintenance costs.
For cracked walls and foundations, we offer injection waterproofing using polyurethane or epoxy resins. This method seals the cracks, stops active leaks, and reinforces the structure. It’s ideal for underground car parks, concrete walls, tunnels, and slabs.
We apply root-resistant membranes and drainage layers to waterproof planter boxes and retaining walls. This protects your surrounding walls and interiors from water seepage and structural decay. Our systems are compatible with green roofs and garden installations.
Our team installs acrylic, bituminous, PVC, and torch-on sheet membranes. We select materials based on your property’s exposure to sunlight, foot traffic, and drainage requirements. These membranes are suitable for both above-ground and below-ground waterproofing projects.
We work with developers, builders, and strata managers across Sydney to provide large-scale commercial waterproofing services. Whether it’s a new apartment complex, retail space, or office building, we tailor our waterproofing to meet regulatory, architectural, and performance needs.
