Stray Current Protection Mat (SCPM)
Trackelast SCPM is a high quality thermoplastic elastomer based material with good insulation properties. It is ideally suited for use as a conformable membrane beneath concrete and ballast.
This product was specifically developed to form an electrical resistant barrier between rail track systems and the surrounding environment. It is therefore called a Stray Current Protection Mat.
