Description
Concretedeck is designed to reduce airborne sound transmission and also reduce impact sound transmission through concrete floors. Concretedeck 18mm, 23mm, and 27mm consist of a 5.5 mm layer of cross-linked Isopoli bonded to 22mm, 18mm and 12mm P5 V313 moisture-resistant chipboard. This concrete floor soundproofing system does not need the additional protection of a moisture barrier (VCL) vapour control layer because the Isopoli will not absorb the moisture from a virgin screed.

When installed as part of a complete party floor construction, it enables a concrete floor to meet the sound transmission standards of ADE 2003 and subsequent amendments in 2004, 2010, 2013 & 2015
Fitting
Concretedeck 27, 23, 18
- ≥300kg/m2 hollow core concrete with 80kg/m2 sand/cement screed or 40mm screed
- Min. 75mm void formed by metal frame suspended ceiling system with ≥10kg/m2 plasterboard board ceiling (top) or 50 x 75mm timber battens.
- ≥10kg/m2 plasterboard board ceiling supported on resilient bars @ 400mm centres, perpendicular to the battens min 75mm below the underside of sub-floor.
Lay Concretedeck flooring over dry level screed in brick bond pattern, applying wood adhesive to all tongued and grooved panel joints. Apply a perimeter isolation tape on the edge of the wall just before the boards are pushed against the perimeter walls to isolate the board from the wall. Install skirting and trim off excess perimeter isolation tape.
Stud Partitions
Stud partitioning should be built from the subfloor wherever possible. It is good practice to isolate all partitions built from the sub-floor with Isolation Tape as this will improve the performance of the walls and the floors.
Skirting Boards and Architraves
Reduce flanking sound by isolating skirting boards and architraves from the flooring. Roll the isolation tape over the flooring and place the skirting board on top. Trim excess tape with a sharp knife.
Kitchens and Bathrooms
Install kitchen units onto the structural subfloor. Lay the concretedeck boards up to the legs of the units. Install the plinth to the legs of the units to finish. Use a plywood sheet or similar over the subfloor where floor heights need to be changed for white goods. The flooring should finish at the legs in the bathrooms, and the subfloor should support the bath. You should then install the bath panel to finish. You can use a plywood sheet below the toilet, bath and sink to ensure the floor height throughout.

Floor and Ceiling Soundproofing
Make sure you are getting the right concrete floor soundproofing for your needs. Understanding the most common types of noise and how to stop them will help you decide the right solution for your floors, ceilings and walls.
Different Types of Sound
- Airborne sounds – Conversation, TV noise and radios are examples of airborne sound. The best way to stop airborne sounds is to add mass/density to the walls or ceilings.
- Impact/vibration sounds – Footfall and moving furniture across a floor are examples of impact sounds. The best way to reduce these sounds is to create separation.
In summary, the best way to reduce airborne sounds is by increasing the mass of the area you would like to soundproof. Reducing impact/vibration sounds is achieved by creating separation within the structure.
Reducing Impact and Airborne Sounds
By following some of these steps, you will ensure you get the best level of soundproofing for your room.
- Mass/Density – Increasing the mass and density of the area you are soundproofing will block airborne sounds from transferring between rooms. You will increase the mass of walls and ceilings using materials such as soundproof panels or high-density acoustic insulation slabs.
- Separation – Incorporating separation within the structure will reduce vibration and impact sounds transferring between rooms. Achieve separation by building independent stud walls and ceilings. If you don’t have the space in the room, you can use acoustic clips and resilient channels to decouple the wall and ceiling.
- Absorption – Use materials that are going to absorb sounds. Acoustic insulation is suitable for sound absorption as it converts the sound waves into heat as it passes through the insulation. Dense mass loaded barriers will also dampen and absorb sound. Use acoustic underlays or floating floors to absorb footfall through timber and concrete flooring.
