VISCOTAQ PE Outer Wrap is a Heavy Duty polyethylene backing in the form of a roll, calendered with an adhesive. The tape is used as an Outer Wrap for the
mechanical protection of VISCOTAQ products against soil stress, back fill procedures and other forms of mechanical impact. Moreover it gives a continuous external pressure to the VISCOTAQ corrosion preventive inner material and forces this material, together with eventual soil stress, continuously to flow. VISCOTAQ PE Outer Wrap is produced from MDPE/HDPE and is wrapped with a 50% overlap onto the VISCOTAQ corrosion preventive coating. The material is applied onto the substrate by hand or by means of a tape wrap machine.
