How to soundproof a concrete floor
To limit the transfer of impact noise through a concrete floor, use a soundproofing solution which adds a cushioning layer to absorb impact vibration. Proven soundproofing insulation like the SoundMat 2 Plus acts like a floating floor, which helps to absorb impact vibration before it enters the structure of the floor.
Unwanted airborne noise through a concrete floor is less common due to the natural high mass of the concrete. If you are experiencing airborne noise contact us to discuss potential weak points.
Soundproofing a concrete floor
The 2 main principles when soundproofing a concrete floor:
Cushioning
The addition of cushioning to the floor means that when an impact such as footsteps, or dragging furniture occurs, this impact is absorbed at the source before it has chance to enter the structure
Isolation
Sound is a physical energy that can travel through solid materials.
Isolating or 'decoupling' one side of the structure from the other creates a breaker to stop that energy from easily transmitting through
Considerations when soundproofing a concrete floor
3 criteria to help determine the correct soundproofing solution:
Final Floor Finish
Different solutions are more suited to different final floor finishes. Choose the most suitable solution depending not only on the noise you are trying to block, but also your final floor finish
Noise Issue
Is the unwanted noise impact vibration (e.g. footsteps) airborne (e.g. talking) or a combination of both? This will determine which soundproofing solution is most suited to your individual situation.
Airborne noise through a concrete floor is less common and could indicate weak points. We'd recommend contacting us to discuss this further
Noise Source
Where is the noise coming from? Is the noise coming from above or below? If it's coming from above, do you have access to the floor above? It's always easier to soundproof at the source of the noise before it enters the structure
