Practical Guide to Remedial Works for Strata Buildings

What Committees & Strata Managers Need to Know

Strata buildings age differently to houses. Shared structures, exposure to weather, and varying maintenance standards mean defects can develop gradually — often out of sight.

Remedial works are not about cosmetic improvement.

They are about protecting the building, managing risk, and preserving long-term value for all lot owners.

This guide explains when remedial works are required, how to approach them correctly, and how strata committees can make informed decisions.

1. What Are Remedial Works in a Strata Context?

Remedial works involve the repair, strengthening, or replacement of defective building elements to restore safety, durability, waterproofing, and compliance.

In strata buildings, remedial works typically address common property, including:

• Structural concrete

• Balconies and podium slabs

• Façades and external walls

• Waterproofing systems

• Car parks and basements

  
  

They go beyond maintenance and are usually required when defects affect performance or safety, not just appearance.

2. Common Remedial Issues in Strata Buildings

Concrete Spalling & Corrosion

One of the most common strata issues.

Causes include:

• Water ingress into concrete

• Corrosion of reinforcement

• Inadequate concrete cover

  
  

If untreated, spalling can lead to falling concrete, reduced structural capacity, and safety risks.

Balcony & Podium Waterproofing Failures

Balconies are high-risk areas because they are:

• Exposed to weather

• Subject to movement

• Often poorly detailed originally

  
  

Waterproofing failures can affect:

• Internal units

• Structural slabs

• Steel reinforcement

  
  

Structural & Non-Structural Cracking

Cracks may result from:

• Building movement

• Shrinkage

• Poor original detailing

  
  

Some cracks are cosmetic, but others indicate deeper issues requiring assessment.

Façade & Building Envelope Defects

Common problems include:

• Cracked render

• Failed sealants

• Loose masonry or panels

• Water penetration

  
  

Façade defects often affect both appearance and performance.

3. Maintenance vs Remedial Works – Understanding the Difference

Maintenance	Remedial
Ongoing upkeep	Corrective works
Minor repairs	Structural or system repairs
Short-term	Long-term solution
Cosmetic	Performance & safety focused

A common mistake is treating remedial issues as maintenance, which often leads to repeat failures and escalating costs.

4. Why Proper Investigation Is Critical

One of the biggest risks in strata remedial projects is skipping proper diagnosis.

Effective remedial planning usually involves:

• Visual inspections

• Targeted investigations

• Understanding water ingress paths

• Identifying root causes

  
  

Without this step, repairs may look good initially but fail again.

5. Typical Strata Remedial Process

A structured approach reduces risk and improves outcomes:

1. Initial inspection & condition assessment

2. Identification of defects and causes

3. Development of repair methodology

4. Budget planning and staging

5. Remedial construction works

6. Quality control and sign-off

   
   

Clear documentation and communication are essential throughout.

6. Budgeting & Planning for Remedial Works

Remedial works can be significant, but poor planning often makes them worse.

Good strata planning includes:

• Allowing for investigations

• Prioritising safety-critical items

• Staging works where possible

• Communicating clearly with owners

  
  

Early action often reduces total cost and disruption.

7. Managing Risk, Safety & Disruption

Strata remedial works often occur while residents remain in the building.

Key considerations include:

• Public safety

• Access control

• Noise and dust management

• Clear communication

  
  

Experienced remedial contractors understand the importance of minimising disruption while maintaining safety.

8. Choosing the Right Remedial Contractor

When engaging a remedial contractor, strata committees should look for:

• Proven remedial experience

• Clear repair methodology

• Transparent scopes and pricing

• Understanding of strata environments

• Focus on long-term outcomes

  
  

Cheapest is rarely best in remedial construction.

9. Why Early Remedial Action Saves Money

Delaying remedial works often leads to:

• Larger repair scopes

• Higher costs

• Increased safety risks

• Insurance and liability exposure

  
  

Early intervention usually results in simpler, more targeted repairs.

Final Thoughts for Strata Committees

Remedial works are about protecting the building and the owners’ investment.

Handled correctly, remedial construction:

• Extends the life of the building

• Reduces future maintenance

• Improves safety and compliance

• Preserves long-term value

  
  

Ignoring defects or applying surface-level fixes often leads to far greater costs later.
