Shielding



What is it about?


By applying shielding measures, flood barriers are installed at some distance from the building or a group of properties. Freestanding barriers or anchored barriers (pillars temporarily fixed at a concrete plate) are usually used. For removable barrier solution, the beams are ending at pillars, which are temporarily fixed at a concrete bearing plate, which surrounds the building. .


Description


Freestanding barriers are cost effective solutions, which need no bearing plate. They resist the floodwater pressure by creating friction between the barrier itself and the ground. On the other hand, this principle can cause hydraulic erosion due to the seepage, and consequently the stability of the barrier can be endangered


Systems/Products available


  • free standing barriers

  • anchored barriers (pillars temporarily fixed at a concrete plate)

There is variety of the systems used such as rubber belts, fibre-plastic coats, inclined barriers or flood protection walls (demountable walls) connected to a fixed support constructions.


Constrains


  • Max height of a freestanding barrier should not exceed 1m

  • Subsoil erosion and hydraulic blow should be studies before as they can cause stability problems

  • Sensitivity of the waterways in the underground
