A synthetic carpet is constructed of different sections of carpet glued together with specialist adhesives on a carrier strip. Over time these adhesives may fail due to weather conditions (especially heavy frosts) and general wear and tear. If rectified immediately it should be possible to restick the failed areas; however, if left unaddressed the forces of general play may cause the two sections of carpet to move apart, causing a GAP. When this occurs simply regluing the sections will leave a trip hazard. In this case a specialist repair will be required to install a new section  of surface to bridge the gap. Care should be taken to avoid inserting small narrow sections of new carpet as these will quickly fail. The correct method is to remove a larger width - including the old seaming tape below the carpet - and replace with new. This ensures a brand new bond which should last for many years to come. More on Repairs.
