Martha Cove Development

DAMTEC® is one of the world’s leading suppliers of high quality and eco-friendly acoustic underlays for the treatment of Impact Noise under all types of floor coverings and also forms part of the Kraiburg group (Est. 1947) which is one of the world’s largest rubber recycling manufacturers. All products are engineered and manufactured in Germany. 

DAMTEC® have carried out extensive and compliant laboratory testing for all types of flooring applications (i.e. tiles, timber, vinyl and carpet) in accordance with the relevant ISO/BCA regulations and hence comply with Part F5 of the Building Code of Australia (BCA). We have also carried out various verification tests on-site to the prevailing site conditions over many years in order to verify compliance of our underlays when installed in-situ.

Part F5 of the BCA states that for compliance the tested floor system MUST achieve an LnTw + Ci rating of 62 or less to be compliant. Remember that the lower the number, the better the performance.

We conducted on-site testing at the luxurious Martha Cove Development for Hickory Developments where our DAMTEC® Standard 2 mm acoustic underlay was installed under a Direct Stick Tile application.

The floor/ceiling composition which is also an important and often overlooked component of the overall performance of the floor system, consisted of a 160 mm thick slab with a 230 mm cavity and a typical 10 mm plasterboard ceiling on the underside.

When tested on-site by an independent acoustic consultant, it was noted that the acoustically treated floor achieved an LnTw + Ci rating of 51 dB and was easily complying with the BCA requirements.

We have also tested our DAMTEC® Standard 3 mm underlay installed under a Direct Stick Timber flooring application at the HM@S building in Melbourne. In this particular instance, there was a 220 mm concrete slab with only a 50 mm ceiling cavity. We achieved an LnTw + Ci rating of 46dB which is compliant with the BCA for Impact Noise.

“Whilst as a company we understand our responsibility is to provide our clients with compliant, laboratory test data for all of our acoustic underlay products under all possible floor finishes, we have noticed an even greater need to also provide the market with specific and individual case study findings to ensure that the Impact Sound performance of a floor system incorporating a DAMTEC® acoustic underlay actually conforms to each and every site specific development and specification due to the varying nature of floor/ceiling construction types and performance criteria from one site to another.”
