  • Compliance: Compliant with both Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland).*
  • Installation: Please see our installation tab below.

Our pimpled under screed underlay specialised for controlling excessive noise issues in concrete structures.

MuteMat® USP 750-08 is our robust, pimpled acoustic under screed resilient layer designed for achieving a greatly improved impact noise reduction between the floating concrete screed and structural concrete slab layers. Its high performance comes from it's deviated pimpled structure which is found at both 8mm and 4mm - helping to secure minimum points of contact between the two 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 vibration that large machinery generates as the floated floor design helps to isolate these acoustic issues.




  • 10m x 1.3m x 8mm (13m2)
  • Specialised as an acoustic under screed.
  • Suitable for concrete structures to effectively attenuate impact noise.
  • Can be installed under a wide range of floor finishes, with no requirement of an overlay.
  • A guaranteed consistent thickness and density.
  • Does not deform, maintains efficiency long term under heavy loads.
  • Pre-fabricated recycled tire granule mat.
  • Compliant with both Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland) and Building Standards Technical Handbook 2017 for Scotland for impact transmission.


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.

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!


How to soundproof a floor

A combination of the following will always result in a much improved acoustic performance.


  • Mass: the addition of more substantial materials to reduce sound energy, for example, added layers combined with soundproof plasterboard.
  • Separation: breaking contact with the surface or surfaces through the use of acoustic isolation clips, or stud framing.
  • Damping: the reduction of vibration through the use of flexible, damping materials such as Tecsound.

MuteMat® USP 750-08 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:

Flooring constructions in concrete structures are made up of a structural concrete slab, often rough, uneven and not suitable for applying floor finishes - and a screed layer that is applied to create a level and much smoother finish. In large concrete structures, especially where there are many dwellings that can cause disruption, it is important to specify the use of a sound proof under screed material to reduce impact and vibration transfer to minimise disruption - the MuteMat® USP 750-08 is a pimpled product that helps to reduce points of contact between screed and structural concrete to assist in floating the screed finish. Although concrete is very effective at reducing airborne noise issues because of its substantial mass, impact noise will tend to travel further and flank through any connected paths because of the dense molecular structure of concrete and the amount of direct contact, this is called Flanking Transmission.

MuteMat® USP 750-17 has a deviated, pimpled finish which gives it minimal points of contact between the floating floor and the sub-floor, and because of this it can be used on a timber structure to treat impact noise issues. It is recommended to cross-fix two layers of 6mm ply, glued and screwed to the top of the MuteMat® USP 750-08 to provide a level and stable floor. Possible uses could be in conjunction with our gym soundproofing products for small home gym projects - where timber structures could suffer from excessive impact noise, and even in recording studios and other audio focused suites along with cinema rooms where separation with the structure is important to reduce vibration from bass frequencies.

Mute Mat™ USF 750-08 requires no adhesive in structural concrete and screed scenarios, it is simply rolled out and taped - ready for a screed layer. For direct application of floor finishes like engineer wood, laminate or luxury vinyl tile, we 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 it is required or not.

10 kN/m2 = < 7% loss of thickness. 15 kN/m2 = < 10.6% loss of thickness. 20 kN/m2 = < 14.3% loss of thickness

MuteMat® USF 750-08 is best cut with a fresh Stanley blade and a straight edge or metal ruler, always cut away from your body and behind the straight edge.
