Playground Trail Thermoplastic playground trails are an exciting way to encourage activity and creative play during break times. Uniplay work alongside nurseries and schools across the UK, helping them to encourage exercise using inspirational playground trails. Our thermoplastic playground trail markings also help children develop social skills and stimulate their imagination. All our markings can be adapted to fit within the space available. We offer playground trails with vibrant colours and limitless patterns to choose from. If you can think it, we can help you bring it to life.
