  • CD for Conventional Drainage

    Rainwater weighs heavy on roofs - a real test for the seal and structural strength. Conventional drainage is the most common type of roof drainage for flat roofs.

     

  • D for Siphonic Drainage

    Do you have particularly large roof areas on industrial, free-standing buildings? And you have a need for great space inside them?

  • PD for Parapet Drainage

    Parapet Drainage removes the water quickly and directly from the roof - with either a pipe system or using waterspouts. Since the drainage is external, it also means that the water stays off.

  • ED for Emergency Drainage

    As climate change takes hold, an increase in heavy rainfall incidents is predicted. You need an emergency drainage system to get the water off your roof if it rains heavily.

  • BT for Balcony and Terrace drainage

    Sita's solutions for balcony and terrace drainage protect your balcony and terrace spaces from flooding and backflow.

  • D for Drainage

    Like a modern water trench, the drainage system at ground level by Sita protects the interior of your building. The facade is also protected from heavy rainfall splashing back.

  • R for Refurbishment

    The older the roof, the greater the risk. As your refurbishment partner we can help you to update your drainage system.

  • V for Ventilation and pipe fairlead

    A well coordinated system is required to ensure your building can breathe in an out, whether it is for room, section or cold roof ventilation.

  • FP for Fire Protection

    All-round-cover - not just when it rains - if there is a fire as well. Sita fire protection solutions prevent the dangerous spread of fire and radiated heat.
