Waterproofing Failure

Indicative Investment Guide : $4,700 - $5,900

Waterproofing failure applies where deterioration has progressed beyond the wall lining and into the waterproof envelope supporting the wet area.

Once the waterproof system can no longer provide reliable protection, isolated repairs and selective wall replacement become increasingly ineffective. Broader reconstruction restores the wet zone from its primary protective layer outward, allowing the new engineered wall system to be installed onto construction designed for long-term performance.

Waterproof failure is often concealed until demolition begins.

For this reason, Aureumus determines the extent of reconstruction by the condition of the wet-zone assembly rather than the visible finish.

This installation approach introduces comprehensive reconstruction only where necessary, replacing failed waterproofing and deteriorated construction while preserving any remaining building elements suitable for continued service.

The qualification criteria below explain where comprehensive wet-zone reconstruction becomes appropriate, the construction it introduces, and the point where replacement of the shower base, floor structure or complete reconfiguration may become the more appropriate solution.

Determining Suitability.

Purpose

Where waterproof failure has compromised the integrity of the wet area, restoring the supporting construction becomes more important than preserving the finished surface.

Comprehensive reconstruction provides a new waterproof envelope before introducing the engineered wall system.

Requirements

Appropriate application generally assumes:

• Existing shower screen removal.

• Existing tapware removal.

• Extensive wall demolition.

• Complete wall lining replacement within affected areas.

• Full waterproof reconstruction.

• Localised structural repairs where required.

• Existing shower base may remain suitable where deterioration has not extended into the floor assembly.

Where deterioration extends into the shower base, floor structure or broader bathroom construction, further reconstruction may become appropriate.

Limitations

This level of reconstruction remains appropriate while deterioration is substantially confined to the wall framework and waterproof envelope.

Where the shower base, floor structure, drainage configuration or broader bathroom layout require replacement, continued remediation of the existing wet area often becomes less practical than introducing a more comprehensive construction solution.

Applications

This level of reconstruction is commonly encountered where:

• Waterproof membranes have failed.

• Moisture has extended beyond the wall lining.

• Multiple construction systems have deteriorated.

• Wall reconstruction alone no longer resolves the underlying condition.

• The wet area requires comprehensive renewal before installation of the finished wall system.

Outcome

Following reconstruction, the completed installation provides:

• Reconstructed wall system.

• New compliant waterproof envelope.

• Premium engineered wall panels.

• New shower screen installation.

• Reinstated shower fittings.

• A renewed wet-zone assembly designed to support the finished installation for long-term performance.

Progression

Progression generally becomes necessary where inspection identifies:

• Shower base replacement.

• Floor structure deterioration.

• Drainage redesign.

• Structural floor reconstruction.

• Integrated shower platform construction.

• Complete wet-area reconfiguration.

Where deterioration extends beyond the wet-zone assembly itself, reconstruction transitions from wall remediation to Shower Base Replacement and complete wet-area renewal.
