Floating Slab Mat

The FSM can be supplied in rolls or sheets. Both are easy to install in single, double or triple layers, plus an underlayer if needed. The system does not have closing joints between adjacent mats, simplifying installation.

The FSM is built to last, with tested long-term stable properties and continued performance. It is water permeable and resistant to atmospheric conditions and fatigue. Each mat has excellent mechanical and chemical properties.

It is compatible with all types of rail and track systems, as well as the curvature of the tunnel invert and special track works such as manholes, pipes and electrical boxes.

The FSM is available in a wide range of stiffnesses, providing different possible levels or providing tuneable ground borne noise vibration isolation. The vibration isolation performance can be modified to meet requirements. Low resonance frequency is from -14 to 25Hz.

The FSM has been proven to mitigate vibration transmission from rolling stock into neighbouring environments. Reductions of between 14db(v) and 25db(v) of recorded vibration levels are possible. Insulation performance can be tuned by modifying the stiffness of the mat or the properties of the slab.

The Pandrol FSM is a continuous mat made of 90% recycled material and 100% recyclable.
