Our most robust under screed underlay specialised for concrete structures.
MuteMat® USP 625-17 is our best performing and most robust pimpled acoustic under screed resilient layer designed for achieving the maximum level of impact reduction between the floating concrete screed and structural concrete slab layers. Its high performance comes from its deviated pimpled structure which is found at both 10mm and 17mm - helping to secure minimum points of contact between the two concrete layers. As a dense and robust product it maintains a low level of compressibility and when subjected to high points loads it maintains its acoustic performance making it suitable for a wide range of applications in residential, commercial and industrial structures, especially where particular low-frequency noise issues and machinery operation is concerned, this is tailored to reduce acoustic issues such as these at a superb level of performance.
Although MuteMat® USP is high performing in concrete builds it can also be implemented in other builds including timber to create a floating floor, with the additional benefit to lay floor finishes directly on top. If you are looking for a general acoustic over screeding product, view our MuteMat® OSF-750 05 and MuteMat® OSF 750-10.

*Our Typical Performance Results and Noise Reduction Guidance are provided to indicate the results that have been achieved in previous tests but are not guaranteed to a specific site as multiple factors can affect this, you can view their variants on our 'Systems' tab.
We endeavour to display the most up to date testing and assist in managing your expectations through each stage of the process so that the choice we make is the right one.
We are always looking for the best ways to describe to you the world of soundproofing through introducing guides that range from the basic principles of sound, how to best soundproof surfaces and what to look for, and how to understand acoustic test data, and this is only naming a few! We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!
A combination of the following will always result in a much improved acoustic performance.
MuteMat® USP 625-17 provides damping and separation, both very important in concrete structures for the minimising of impact noise. The mass is often sufficient in the concrete slab itself but is improved further with the separation of the screed layers mass applied on top. For projects that are expecting greater or excessive noise issues, combined with our MuteClip® systems on both walls and ceilings.
In under screed projects, there are a few options available, and each looks to separate the structural concrete slab from the surrounding surfaces and to float the new screed. Screed is the 'wet' levelling finish either applied directly to a concrete slab, which is often a 'rough' aggregate finish that is uneven or to composite floor build ups, for instance, on top of an acoustic layer. Before applying liquid or flow screeds, each room must use a Perimeter Flanking Band around the perimeter so that your soundproof under screed, screed and your chosen floor finishes can butt up against it. This Flanking Band is to minimise contact with the walls, because of the screed finish is touching it is going to reduce the floors flexibility to deal with impact noise or vibration and transfer through this path through Flanking Transmission, all floor layers need isolation. Then, depending on what your project requires, an acoustic under screed is installed, and you will find this type of soundproofing in a lot of new builds, including residential complexes and in areas containing large machinery or gymnasiums.

This product is part of the following systems:
Concrete constructions are made up of a structural concrete slab which is a blend of sharp, uneven aggregates - leaving a rough finish, a screed layer is then applied over the top to levelling out the unevenness to leave a smoother finish. In most cases, and especially in large residential structures, before the screeding stage most will specify the use of an under screed soundproofing material to assist in floating away the screed from the structural concrete to sound proof the floor against impact noise. Concrete is very effective at reducing airborne noise issues because of it’s incredible mass, where impact noise will tend to travel further and flanks through any connected paths because of the amount of direct contact, this is called Flanking Transmission.
MuteMat® USP 625-17 is a pimpled sound proofing material that deviates between two levels to provide minimal points of contact with the sub-floor and the floor finish, and because of this structure it can be used on a timber structure to treat problematic impact noise issues that require maximum separation. It is recommended to cross-fix two layers of 6mm ply, glued and screwed to the top of the MuteMat® USP 625-17 to give a level and stable base for flooring to be installed. This can be used in small personal gym areas at home alongside our specified gym sound proofing products where timber structures would often suffer from the excessive impact noise that weight drops or use of treadmills generate. Recording studios and other audio environments also generate a high degree of low frequency content which needs separation in the structure to soundproof it efficiently by reducing the direct paths these low frequencies can travel through with ease.
Mute Mat™ USP 625-17 requires no adhesive in structural concrete and screed scenarios, it is simple rolled out and taped and butted against a Perimeter Edging Strip which is required to line each room to reduce Flanking Transmission - it is now ready for a screed layer. For direct application of floor finishes like engineer wood, laminate or luxury vinyl tile as examples, we would would recommend the installation of two layers of 6mm ply cross-fixed with glue and screw to leave a stable base.
This will often be for the specifier to decide on whether if it is required or not.
