Abstract: front page image
(EN)


A method of imparting
strength to earth in support of a ground surface
is disclosed. A bag is placed in the earth
under the ground surface, the bag having a
first end oriented towards the ground surface,
a second end opposite the first end, and
a cross sectional contour from the first end to
the second end that includes at least one
wedge portion extendable laterally into
surrounding earth located above and below the
wedge portion when the bag is filled. A
expandable polymeric resin is injected into the
bag to at least partially fill the bag to
compress earth around the bag. The expandable
polymeric resin may be expandable polymeric
resin. A bag is also disclosed for use in
imparting strength to earth in support of a
ground surface. The bag comprises at least
an opening, a first end and a second end
opposed the first end, and a cross sectional
contour from the first end to the second end
that includes at least one wedge portion
extendable laterally into surrounding earth
above and below the wedge portion when
the bag is filled and in earth under the
ground surface
