All T-Pads are suitable for use with all conventional paving and decking systems. Features Thickness: 3mm. Diameter: 150mm. Manufactured from polypropylene. Compatible with TP10 and TP15, for use where fine height adjustment is required to compensate for imperfections in the area that is to be paved or decked.
