Common Issues in Apartment Buildings (and How Engineers Fix Them)

Apartment buildings are complex structures. Over time, design limitations, construction defects, environmental exposure, and general wear and tear can lead to recurring issues that affect safety, durability, and compliance. This guide outlines common problems found in apartment buildings and how engineers resolve them.

Concrete Cracking and Spalling

Cracks, rust staining, and concrete delamination are frequently observed in balconies, slabs, columns, and basement structures. These issues are commonly caused by water ingress, corrosion of steel reinforcement, poor detailing, or long-term exposure to harsh environments.

Engineers assess concrete damage early to prevent further deterioration and loss of structural capacity.

Water Ingress and Waterproofing Failures

Water leaks through balconies, roofs, basements, façades, and planter boxes are a major concern in apartment buildings. If left unresolved, water ingress can cause internal damage, mould growth, and accelerated structural deterioration.

Engineers investigate the source of leaks, review existing waterproofing systems, and provide coordinated remedial solutions that address the root cause rather than just the visible symptoms.

Façade Defects and Cladding Issues

Façade-related issues such as cracking, failed sealants, loose cladding, and movement between materials are common, particularly in older buildings or poorly detailed developments. These defects can affect safety, appearance, and regulatory compliance.

Engineers carry out façade condition assessments, movement analysis, and compliance reviews to develop practical and durable rectification strategies.

Structural Movement and Settlement

Structural movement can present as cracking in walls, uneven floors, or doors and windows no longer operating correctly. Causes may include soil movement, footing design limitations, or changes in loading over time.

Engineering assessments help determine whether movement is cosmetic or structural and identify appropriate solutions.

Fire and Safety Upgrade Requirements

Many apartment buildings require structural input during fire and safety upgrades, particularly when modifying fire stairs, penetrations, or load-bearing elements. Older structures often need assessment to confirm they can support upgraded systems.

Engineers provide structural assessments, certification, and compliant upgrade designs in coordination with fire engineers and certifiers.

Non-Compliant or Aged Structures

Apartment buildings constructed decades ago may not meet current Australian Standards or NCC requirements. This often becomes apparent during renovations, approvals, or regulatory reviews.

Engineers assess existing structures, provide engineering justifications, and design strengthening or upgrade works where required.
