Watertight doors

The ideal solution for your house, cottage or garage. Watertight doors can also be used in industrial buildings, where they protect against water ingress into administrative or production areas, IT rooms, archives and other sensitive spaces. Quick seal activation and minimal requirements on maintenance.

  • Watertight doors tailor made for each application.
  • Design and functionality like classic hinged doors.
  • Quick seal activation (manual or automatic).
  • Minimal requirements on maintenance.


Watertight doors prevent ingress of water into houses or other buildings in the
event of floods or torrential rain. Quick and easy activation whenever needed.

Design and functionality like classic hinged doors

PPD AL watertight doors fulfill the function of standard doors and are
indistinguishable from them at first sight. You can choose from a wide spectrum
of RAL colours, various types of fittings, various dimensions, types of glazing and
other equipment.

Water-tightness and reliability

The water-tightness of the door is ensured by a full-circuit inflatable EPDM seal located in the door leaf and a stainless steel strip in the door frame. In two versions – with water column height of 1 or 5 m, other atypical solutions on request.

This system is activated by inflating the EPDM seal using a valve located in the box next to the door, either manually by inflator, compressor, CO2 bottle, pressure cylinder, or automatically by the control unit using a flood sensor, a button on the control unit or remotely. The standard features of these doors are the same as for conventional doors. Choice of left or right opening, colour, dimensions and other retrofitting.

System activation

Activation is done manually by means of a lever mechanism on the door leaf.
