Why Apartment Flooring Is Different
Choosing flooring for an apartment is not the same as choosing for a house. You are dealing with shared walls, concrete substrates, body corporate rules, and neighbours directly below your feet. Get it wrong and you face noise complaints, strata fines, or forced removal of your new floors.
Here is what makes apartments unique:
- Concrete slab substrate - most apartments sit on reinforced concrete, which transmits impact noise directly to units below
- Strata by-laws - body corporates require certified acoustic testing before approving hard flooring
- Impact noise transfer - footsteps, dropped items, and furniture movement travel through the structure
- Height restrictions - limited floor-to-ceiling clearance means thinner flooring systems are preferred
- Moisture from concrete - slabs release moisture for years after construction, requiring waterproof flooring

Australian Acoustic Requirements Explained
The Building Code of Australia (BCA) sets a minimum standard for impact noise between dwellings: Ln,w + CI must not exceed 62 dB. This is the national baseline, but most strata schemes require performance well above this minimum.
The AAAC Star Rating System
The Association of Australian Acoustical Consultants (AAAC) created a star rating system that most body corporates reference in their by-laws:
| Star Rating | Ln,w + CI (dB) | Performance Level | Typical Requirement |
|---|---|---|---|
| 2 Star | 62 | BCA minimum | Rarely accepted by strata |
| 3 Star | 57 | Basic comfort | Older buildings |
| 4 Star | 52 | Good comfort | Most strata schemes |
| 5 Star | 47 | High comfort | Premium buildings |
| 6 Star | 42 | Excellent | Luxury developments |
Check your by-laws first
Every body corporate is different. Some require 4-star minimum, others demand 5-star. Always request your building's specific acoustic requirements in writing before purchasing flooring.
State-by-State Strata Rules
Queensland: Body corporates can enforce acoustic flooring requirements even without specific by-laws. The Body Corporate and Community Management Act allows committees to require acoustic testing for any hard flooring installation.
New South Wales: Strata by-laws commonly require written approval from the owners corporation before installing hard flooring. NSW has the strictest enforcement, with tribunals regularly ordering flooring removal for non-compliance.
Victoria: Owners corporations can set acoustic requirements through special resolutions. Most Melbourne apartments built after 2004 have acoustic flooring by-laws embedded in the owners corporation rules.
Best Flooring Types for Apartments
Not all flooring performs equally in apartment settings. Here is how the main options compare across the factors that matter most in multi-level living.
| Flooring Type | Acoustic Rating | Concrete Slab | Waterproof | Thickness | Strata Friendly |
|---|---|---|---|---|---|
| SPC Hybrid | Excellent (with underlay) | Perfect | 100% | 6.5-9.5mm | Yes |
| Engineered Timber | Good (with underlay) | Good | No | 15mm+ | Yes |
| Luxury Vinyl Plank | Good | Good | Yes | 4-6mm | Sometimes |
| Laminate | Poor | Acceptable | No | 8-12mm | Rarely |
| Solid Hardwood | Poor | Difficult | No | 19mm+ | Rarely |
Why SPC Hybrid Wins for Apartments
Why SPC hybrid is ideal
- Stone polymer core does not expand or contract on concrete
- 100% waterproof - handles bathroom, laundry, kitchen
- Click-lock floating install means no adhesive on the slab
- Thin profile (6.5-9.5mm) preserves ceiling height
- Rigid core pairs perfectly with acoustic underlay
- Achieves 5-star acoustic ratings with correct underlay
- No acclimatisation period needed
Considerations
- Must use quality acoustic underlay (not included in basic install)
- Acoustic test report needed for strata submission
- Expansion gaps required at all walls and transitions
- Some body corporates require specific brand certifications

How to Get Strata Approval
Getting body corporate approval for hard flooring typically takes 2-6 weeks. Here is the process most strata schemes follow:
1
Request Your By-Laws
Contact your body corporate manager and ask for the specific acoustic flooring requirements. Get the required star rating and any approved product lists in writing.
2
Choose a Certified Flooring System
Select flooring with a tested acoustic underlay combination that meets your building's star rating. The flooring and underlay must be tested together - you cannot mix and match uncertified combinations.
3
Submit Your Application
Provide the acoustic test certificate, product specifications, proposed installer details, and installation timeline to your body corporate committee.
4
Wait for Approval
The committee reviews at their next meeting (monthly in most buildings). Some require a special resolution at an EGM for major renovations.
5
Install and Certify
Use a qualified installer who follows the manufacturer's specifications exactly. Some buildings require a post-installation acoustic test to confirm compliance.

Acoustic Underlay - The Critical Layer
Your flooring choice only delivers half the acoustic performance. The underlay beneath it does the heavy lifting for noise reduction. Without proper acoustic underlay, even the best SPC hybrid will fail strata requirements.
Acoustic underlay can reduce impact noise by up to 75%. The underlay absorbs vibration before it reaches the concrete slab, preventing sound transmission to the unit below.

What to Look For in Acoustic Underlay
- Thickness: 1.5mm-3mm for SPC hybrid (thicker is not always better - too thick can compromise click-lock integrity)
- Material: Rubber or rubber-cork composite delivers the best IIC (Impact Insulation Class) scores
- Certification: Must have a tested acoustic rating when paired with your specific flooring product
- Moisture barrier: Essential for concrete slabs - look for integrated vapour barrier or install separately
- Compatibility: Must be approved by your flooring manufacturer to maintain warranty
Pre-attached vs separate underlay
Some SPC hybrid products come with acoustic backing pre-attached. This simplifies installation but check the acoustic rating - pre-attached pads are often thinner and may not meet 5-star requirements on their own. You may still need additional underlay beneath.
Installing on Concrete Slabs
Apartment concrete slabs present specific challenges that differ from timber subfloors in houses. Here is what matters:
Moisture Testing
Concrete slabs retain moisture for years. Before installing any flooring, a relative humidity test should read below 75% RH (or as specified by the flooring manufacturer). New buildings under 12 months old almost always require a separate moisture barrier.
Slab Flatness
SPC hybrid flooring requires the concrete to be flat within 3mm over 1 metre. Most apartment slabs meet this standard, but check for:
- High spots where floor levelling compound was applied unevenly
- Dips around plumbing penetrations
- Ridges from formwork joins
- Leftover tile adhesive from previous flooring (must be scraped flat)
Floating vs Glue-Down
For apartments, floating installation (click-lock) is almost always preferred:
- No adhesive bonding to the slab means easier future removal
- Acoustic underlay sits freely between flooring and concrete
- Faster installation with less mess (important in occupied buildings)
- No curing time - walk on immediately after installation

Frequently Asked Questions
Can I install hard flooring in my apartment without strata approval?
No. In Queensland, NSW, and Victoria, installing hard flooring without body corporate approval can result in orders to remove the flooring at your expense. Some buildings also impose fines. Always get written approval before starting work.
What happens if my flooring fails the acoustic test?
If a post-installation acoustic test fails, you will typically be required to either add additional acoustic treatment (such as a secondary underlay or ceiling treatment in the unit below) or remove and replace the flooring with a compliant system. This is why choosing a pre-certified flooring and underlay combination is critical.
Is SPC hybrid flooring loud to walk on?
SPC hybrid with quality acoustic underlay is quieter than laminate and comparable to engineered timber. The rigid stone polymer core is denser than standard vinyl, which helps dampen in-room sound. The key is the underlay quality - cheap foam underlay produces a hollow sound, while rubber-based acoustic underlay delivers a solid, quiet feel.
Can I use the same flooring in my apartment bathroom?
Yes - SPC hybrid is 100% waterproof and suitable for bathrooms, laundries, and kitchens. This is a major advantage over engineered timber and laminate, which cannot handle wet areas. You can run the same floor throughout your entire apartment for a seamless look.
How thick should acoustic underlay be for apartments?
For SPC hybrid, 1.5mm to 3mm rubber or rubber-cork composite is ideal. Thicker is not always better - going beyond 3mm can compromise the click-lock connection and void your flooring warranty. Always use the underlay thickness recommended by your flooring manufacturer.
Do ground-floor apartments need acoustic underlay?
Ground-floor apartments above car parks or commercial spaces still require acoustic compliance. However, if your apartment is on a concrete slab with no dwelling below (such as ground floor on a slab-on-ground), you may not need acoustic underlay for strata compliance. Check your by-laws - some buildings require it universally regardless of level.
How long does the strata approval process take?
Typically 2-6 weeks. Most body corporate committees meet monthly, so timing your application to arrive before the next meeting can save a month. Some buildings have a fast-track process for pre-approved flooring products.
