Floating Slab Mat

Pandrol Floating Slab Mat (FSM) is a high performing vibration attenuation floating slab system based on the mass-spring principle, where the concrete slab (the mass) is elastically supported by a continuous resilient mat (the spring).

Pandrol FSM are made of high quality resin-bonded rubbers. Depending on these design parameters, the Pandrol FSM solutions can achieve a vibration attenuation up to 25 dBv with a low resonance frequency.

Technical Features

The elastic properties of the mat solution are defined by the following parameters;

Track and train design
Chosen material type
Defined thickness and number of layers
Determined shape factor

Advantages

Can be supplied in rolls or sheets, both options easy to install and compatible with all types of rail and track systems
Water permeable and maintenance free, the Pandrol FSM is designed to reduce the life cycle costs of the railway
Insulation performance can be tuned by either modifying the stiffness of the mat or the properties of the slab
Each mat has excellent mechanical and chemical properties and is compatible to special track works such as man-holes, pipes and electrical boxes
