What is SPU?
It's a design based on human kinetics and physical characteristics
flooring system, with hard top layer combined with soft rebound cushion lower layer structure. It's suitable to lay on concrete or asphalt substrates.
The cushion layer is formed by single component modified
polyurethane and top up with two-component modified acrylic
resilience layer.
