Scour and erosion protection

Protecting against loss of soil around underwater structures

Our products combine ballast with filtration to withstand the strong shear forces involved with underwater foundation elements such as piles, quay walls and bridge abutments.

Scour is the result of bottom shear stress induced by water velocity. Once this becomes higher than the critical shear stress, soil will be transported away from the foundation element posing stability risks to the superstructure.

The foreshores of quay walls are subject to erosion due to turbulent ship propeller forces and vortices. Enka-Mattress can secure the structure. You can defend critical riverbank sections and attacked seashore areas by Enka-Fix with precast concrete blocks.

OUR SOLUTION

Typically, Our products for scour protection combine ballast with filtration to withstand the stronger shear forces in these situations.

Enka-Mattress

  • Lost-shuttering mattress follows soil surface perfectly.
  • No gaps subject to erosion.
  • Becomes a robust, rigid long-lasting protection layer.
  • Can also be zipped around or layed down over pipelines.
