Ensure Waterproofing & Remedial Building's
Remedial waterproofing is the diagnosis and repair of failed or deteriorating waterproofing systems in existing buildings. Unlike new-build waterproofing, remedial work requires licensed, comprehensive diagnosis - identifying and treating the problem at its source, not just its symptoms.
For strata and commercial buildings on the Central Coast, it's one of the most common building waterproofing services required. Coastal conditions accelerate membrane breakdown, and much of the region's strata stock is now exceeding the lifespan of its original systems.
Ensure Waterproofing are licensed under the NSW Design and Building Practitioners Act. Every remedial waterproofing project is assessed, designed, and fully documented - giving strata managers and owners corporations the compliance they need.
Not sure if your building needs remedial waterproofing?
Water damage rarely announces itself early. By the time it's visible, the underlying failure has usually been active for months, sometimes years. These are the most common signs that your building requires professional remedial waterproofing services.
Bubbling, Peeling or Flaking Paint Paint that lifts, blisters, or flakes from walls and ceilings signals moisture trapped beneath the surface. This is common in Central Coast buildings where coastal humidity accelerates deterioration of waterproofing membranes and surface coatings.
Concrete Cancer Rust-coloured staining, cracking, or spalling concrete on balconies, carparks, and facades indicates steel reinforcement corroding from water infiltration. Left untreated, concrete cancer compromises structural integrity and becomes a significant strata liability.
Rising Damp White salt deposits, crumbling mortar, or a persistent damp smell at the base of walls are signs of rising damp. Groundwater is wicking upward through masonry, degrading the structure from the ground up.
Mould Growth Recurring mould in areas that are not wet-use rooms points to chronic moisture intrusion rather than surface condensation. In strata buildings, this is often a building envelope issue, not a tenant issue.
Failed or Visible Membrane Cracked, lifting, or visibly degraded membrane on balconies, rooftops, or podiums indicates the waterproofing system has reached end of life and requires full remedial assessment.
The Central Coast presents specific challenges for building waterproofing. Coastal salt air accelerates membrane and sealant deterioration, and a large proportion of the region's strata and commercial stock was built in the 1980s and 1990s, meaning original waterproofing systems are at or beyond end of life. Our remedial waterproofing services address the full range of defects found in Central Coast buildings, both above and below ground.
Every remedial waterproofing project we undertake follows the same structured five-step process. For strata managers and owners corporations, this means a clear scope, documented compliance, and no surprises.
Water ingress in a strata scheme rarely affects a single lot. It travels through shared structure, crosses lot boundaries, and creates liability that requires documented, compliant remediation rather than a reactive patch.
Ensure Waterproofing are registered under the NSW Design and Building Practitioners Act. Every strata waterproofing project includes a compliant design, full scope of works, and complete documentation for OC records, meeting the requirements insurers, certifiers, and NCAT expect.
On the Central Coast, a high concentration of strata schemes built in the 1980s and 1990s are now seeing original membranes fail across balconies, podiums, rooftops, and basements simultaneously. We work with strata managers and owners corporations to assess defects across the full scheme and deliver a coordinated remediation programme, reducing long-term cost and disruption compared to lot-by-lot repairs.

Remedial waterproofing is the process of repairing failed or deteriorated waterproofing systems in existing buildings. It addresses water ingress, moisture penetration, mould growth, and potential structural damage. Professional remedial waterproofing restores compliance with building codes and protects the long-term integrity of your property.
Common warning signs include efflorescence, water stains, mould growth, damp patches, cracking surfaces, and peeling paint. These symptoms often indicate underlying waterproofing failures that require expert Central Coast waterproofing assessment and repair.
Common signs of waterproofing failure in an apartment include:
Because apartment buildings share walls, balconies, façades, and common property, water ingress in one unit can quickly spread to affect neighbouring units and shared structural elements. If you notice any of these signs, remedial waterproofing should be assessed promptly to identify the source. Remedial waterproofing for apartments requires coordinated solutions that meet strata compliance and building performance requirements, since fixes often involve common property rather than just an individual unit.
Remedial waterproofing is applied to an existing structure that has already shown water damage or failure, while regular (new) building waterproofing is installed during construction, before finishes are laid, as a preventative measure.
Key differences include:
For apartment buildings, remedial waterproofing is typically more complex than standard building waterproofing because a failure in one area can affect multiple units, and any repair needs sign-off through the body corporate before work begins.
