Why Rubber Crumb Cradles?

Quick installation and long-lasting performance
Sonixx® Rubber Crumb Cradles offer rapid installation and exceptional, long-lasting performance. Manufactured using recycled rubber crumb, these cradles and base packers can be overlaid with chipboard, plywood, cement particle board or hardwood to produce premier acoustic and sports floors, which can accommodate a diverse range of floor coverings.

How the rubber crumb cradle is used

See below a short animation of how our Rubber Crumb Cradles are used, whether that be for Raised Acoustic, Sports Flooring or External Decking.

How the rubber crumb system works


Easy Levelling
The cradles enable quick and simple levelling of uneven subfloors, through the use of 2mm and 5mm cradle packers positioned
within the cradle legs and below the battens. Additional levelling can be achieved via 10mm and 30mm cradle base packers.



Versatile System
As the cradles are placed directly on the subfloor, no levelling screeds are required. This eliminates the need for wet trades, thereby significantly reducing preparation time and installation costs, as well as streamlining programming and on-site processes. The versatility of the system allows for a wide range of finished floor heights to be achieved.
