The Pulsar flooring kit is cut from high quality impact resistant interlocking rubber tiles. Our flooring is waterproof and shock resistant. Tiles come in 61cm x 61cm interlocking rubber squares, 10mm thick. The tiles, in conjunction with the supplied heavy duty plastic membrane, provide a flooring surface that is not only waterproof, but also shock resistant to protect falling eyepieces etc! Also reduces noise and vibration, and provides good insulation from the concrete base.
