A method of manufacturing a carpet or carpet tile, the method comprising: a) providing a facecloth, wherein the facecloth comprises a primary backing having a plurality of face yarns extending through the primary backing; and b) forming a multi-layer construction comprising the facecloth and a backing construction secured on a bottom side of the facecloth by: i) applying a polyolefinic coating onto the bottom side of the facecloth; ii) pressing a first side of a reinforcing scrim layer onto the bottom side of the facecloth; and iii) extruding a polyolefin-based resin onto a second side of the reinforcing scrim layer, thereby forming an extruded polyolefin sheet having a top surface which is bonded to the reinforcing scrim layer; or i) applying a polyolefinic coating onto the bottom side of the facecloth; ii) extruding a polyolefin-based resin onto the bottom side of the facecloth, thereby forming an extruded polyolefin sheet having a top surface which is bonded to the facecloth; and iii) pressing a first side of a reinforcing scrim layer at least partially into a bottom surface of the extruded polyolefin sheet; wherein the polyolefinic coating has a viscosity less than 2000 mPa.s at 204 °C (400 °F), said viscosity being measured via capillary rheometer, according to ASTM D3835. a) providing a facecloth, wherein the facecloth comprises a primary backing having a plurality of face yarns extending through the primary backing; and b) forming a multi-layer construction comprising the facecloth and a backing construction secured on a bottom side of the facecloth by: i) applying a polyolefinic coating onto the bottom side of the facecloth; ii) pressing a first side of a reinforcing scrim layer onto the bottom side of the facecloth; and iii) extruding a polyolefin-based resin onto a second side of the reinforcing scrim layer, thereby forming an extruded polyolefin sheet having a top surface which is bonded to the reinforcing scrim layer; or i) applying a polyolefinic coating onto the bottom side of the facecloth; ii) extruding a polyolefin-based resin onto the bottom side of the facecloth, thereby forming an extruded polyolefin sheet having a top surface which is bonded to the facecloth; and iii) pressing a first side of a reinforcing scrim layer at least partially into a bottom surface of the extruded polyolefin sheet; wherein the polyolefinic coating has a viscosity less than 2000 mPa.s at 204 °C (400 °F), said viscosity being measured via capillary rheometer, according to ASTM D3835. i) applying a polyolefinic coating onto the bottom side of the facecloth; ii) pressing a first side of a reinforcing scrim layer onto the bottom side of the facecloth; and iii) extruding a polyolefin-based resin onto a second side of the reinforcing scrim layer, thereby forming an extruded polyolefin sheet having a top surface which is bonded to the reinforcing scrim layer; or i) applying a polyolefinic coating onto the bottom side of the facecloth; ii) extruding a polyolefin-based resin onto the bottom side of the facecloth, thereby forming an extruded polyolefin sheet having a top surface which is bonded to the facecloth; and iii) pressing a first side of a reinforcing scrim layer at least partially into a bottom surface of the extruded polyolefin sheet; wherein the polyolefinic coating has a viscosity less than 2000 mPa.s at 204 °C (400 °F), said viscosity being measured via capillary rheometer, according to ASTM D3835.
