Abstract
A retaining-wall block has a set of liquid impervious walls defining a completely bounded cavity having a sealable opening for filling the cavity with a fill material to add weight, and a seal element for sealing the sealable opening. In some cases the block has a second cavity with openings for collecting liquid and for passing collected liquid out of the second cavity to adjacent blocks in an assembly.
Claims17
A retaining-wall block comprising:
- a set of liquid impervious walls defining a completely bounded first cavity having a sealable opening for filling the cavity with a fill material to add weight;
- a second cavity defined by the set of liquid impervious walls and adjacent the first cavity, the second cavity separated from the first cavity by at least one of the liquid-impervious walls;
- and
- a seal element for sealing the sealable opening of the first cavity;
- characterized in that the second cavity comprises through-openings to the outside of the block for accepting drainage liquids, and for passing said liquids out of said second cavity.

A retaining wall assembly of blocks comprising;
- a plurality of individual hollow blocks, individual ones of said blocks comprising a set of liquid impervious walls defining a completely bounded first cavity having a sealable fill opening for filling the first cavity with a fill material to add weight;
- and
- a second cavity in the individual ones of the blocks adjacent the first cavity, defined by the liquid-impervious walls and separated from the first cavity by at least one of the liquid-impervious walls;
- wherein the second cavity comprises through-openings to the outside of the block for accepting drainage liquids, and for passing said liquids out of said second cavity.
