Contractor Mitchellson Formwork opted for the DOYMA Curaflex pipe sleeve – 3000 and 3000T –as well as the 3001 DOYMA Curaflex pipe sleeve. Also specified was the DOYMA Curaflex 5000 pipe sleeve systempipe sleeve system.
Benefits of the 3000 and 3000/T solutions include homogeneous connection to concrete enhanced by special grooving, plus the inside face of the sleeve provides an optimum contact surface for the elastomer of the Curaflex gasket insert. It forms a watertight bond with the concrete because the coefficient of expansion of the material corresponds to that of concrete and is ideal for buildings without tanking membranes.
The DOYMA Curaflex 3000 and 3001 pipe sleeves are manufactured from a dimensionally stable and resistant special fibrous cement; /T denotes split version for retrofitting around pre-installed services which can then be sealed using a split gasket. The capability to seal leaking service entries without having the inconvenience of disrupting continuity of service resulting from service disconnection is a real advantage.
The DOYMA Curaflex 5000 pipe sleeve is a steel version for high static loads with integrated fixed and loose membrane clamping flanges and can also be installed flush within the shuttering. DOYMA Curaflex sleeves are fire resistant and, in conjunction with an intumescent packing appropriate to the ducted service, not only seal against water ingress (watertight up to 3 bars pressure) but also stop the spread of fire.
