Isocheck Re-Mat Base Under Screed Improvement System

Isocheck Re-Mat Base 3, 5, 6 & 10

Under screed impact improvement systems

The Isocheck Re-Mat Base 3, 5, 6 & 10 under screed impact improvement systems are designed to reduce impact sound transmission through all types of structural concrete floors where a screed floor finish is also required. If installed correctly provides sufficient impact absorption to place it amongst the top performing systems available.

Isocheck Re-Mat Base 3, 5, 6 & 10 comprises 3mm, 6mm and 10mm (for high load) reconstituted bonded rubber layer that has been designed to be placed within a masonry structural floor directly below the screed. Isocheck Re-Mat Base 3, 5, 6 & 10 have been tested to BS EN 29052-1:1992 and satisfy the dynamic stiffness requirement with a figure of 10MN/m3.

To be used on concrete beam and block, hollow core, in-situ and all other types of concrete structural subfloors, for conversions, refurbishments or new build. This isolates the screed from the structural sub floor. By ensuring that all the joints are taped, bridging will be eliminated which is the single greatest cause of failure of any system of this type.

Construction complies with the latest version of Approved Doc E of the building regulations. Under separate UKAS laboratory site tests, the construction above was found to provide a Dntw+Ctr of 49dB and an Lntw of 48dB.

Isocheck Re-Mat Base 3, 5, 6 or 10 under screed impact improvement system, supplied by Isomass Ltd. Unit 14 Papworth Business Park, Stirling Way, Papworth Everard, Cambridgeshire CB23 3GY and installed in accordance with manufacturer’s instructions / recommendations.

The floor surface should be swept free of any loose debris that may damage or bridge the system.

Butt joint and seal all roll edges of isocheck Re-Mat Base 3, 5, 6 or 10. At perimeters butt Re-Mat Base 3, 6 or 10 onto a right angle flanking edge strip which should be turned up all vertical surfaces to allow a minimum 50mm to protrude above the intended FFL of the screed.

Perimeter butt joints should be sealed with a min. 100mm wide duct tape.

Services that penetrate the screed should be isolated by wrapping with Re-Mat Base 3, 5, 6 or 10 which again would be taped.

Installation instructions is available to be used in conjunction with this information and/or information contained in the datasheet when laying these floor systems.
