Did you know… that Reinforced Earth structures also work under water?
you know...that Reinforced Earth® structures also work under water?
Reinforced Earth® structures can be designed to be partially or even fully
submerged by water.
The stability of the structures is checked for all critical conditions
(lowest water level, highest water level, rapid draw down). Effective
stresses, pore water pressures and in some cases pore water flows are taken
into account in the design.
In case of rapid changes in water level,
backfills with high drainage capacity are specified. Our segmental concrete
facings, separated by open joints, have a high water discharge capacity.
Filter conditions have to be well designed and followed on the site.

The type of soil reinforcement is adapted to the chemical harshness of
the environment. The pull-out capacity of all our range of reinforcement
has been tested and calibrated in saturated soils.
Particular care is taken regarding the risk of scour at the toe of structures
along running water courses.
Reinforced Earth walls built for the Prado dam inlet and outlet (CA, USA)
or for the Port Cartier quay wall (QC, CA) are good examples of structures
submitted to constantly varying water levels.
