General Enquiry

Dyrhoff is pleased to provide technical advice, product information, preliminary design drawings, budget prices or a full technical and/or commercial proposal for any project involving inflatable rubber dams and/or spillway gates anywhere in the world. As each project is different and each rubber dam or spillway gate is custom built, it is important to provide us with as much information as possible about the project and the gate operating requirements at an early stage.

Such information would normally include:

  • Maximum upstream and downstream water levels across the rubber dam
  • River flow characteristics including maximum velocity
  • Maximum overflow depth (overtopping) when rubber dam is fully inflated
  • Type of rubber dam (air-inflated or water filled)
  • Required time for inflation/deflation (average is 60 minutes)
  • Type of control/operating system (manual/automatic)
  • Location of control room relative to rubber dam (distance)
  • Type and quality of fixings (carbon steel, 304 or 316 stainless steel)
