Strata Waterproofing Sydney
Waterproofing and remediation for apartment buildings, common property and strata schemes.
Waterproofing in a strata building is rarely a simple repair. Water that enters at a balcony or bathroom on one level emerges in someone else's home on another, which means the work involves multiple lots, common property boundaries, owners corporation approvals and residents who need to know what is happening and when.
Diamond Seal Waterproofing works with strata managers, owners corporations, building managers and committees across Sydney on waterproofing remediation and new waterproofing works in apartment buildings.
Water ingress across lots and common property
Strata water ingress typically presents as a defect report: a stain on a bedroom ceiling, damp appearing in a hallway, or efflorescence under a balcony soffit. The affected owner is not usually the owner of the area causing it.
Resolving it requires establishing where the water is entering, which element is involved, and what remediation that element needs — information the owners corporation needs before it can make decisions about scope, access and scheduling.
What strata waterproofing involves
Defining the affected element
Identifying whether the balcony, bathroom, roof, planter or common area structure is the origin of the ingress.
Scope for the owners corporation
Providing a clear description of the works so decisions can be made and scheduled.
Resident and access coordination
Arranging access to lots and common areas with notice, and working to agreed hours where required.
Remedial waterproofing
Removal, preparation, detailing and reinstatement of the waterproofing system in the affected areas.
Reinstatement
Coordinating tiling and finishes so lots and common areas are returned to a usable condition.
