Geotechnical barrier

(57)    Abstract

A geotechnical barrier includes a first barrier layer (18), a second barrier layer (24) overlying the first barrier layer and spaced therefrom, at least one of the

first and second barrier layers (18,24) being geosymthetic barrier layer (18) and the first and second barrier layers (18,24) defining, at least in part, a

fluid
passageway (52) having an inlet and an outlet (34); and fluid displacement

means (50) connected to the outlet (34) and adapted to regularly provide a negative pressure at the outlet (34); and fluid displacement means (50)

connected to the outlet (34) and adapted to regularly provide a negative pressure at the outlet (34) with respect to the pressure at the inlet, thereby

to
