Berm and method of construction thereof

A combination of an existing landfill and a berm to increase capacity of the existing landfill, the landfill comprising a waste-receiving recess having a surface and an outer perimeter, an edge surface peripherally adjacent at least a portion of the outer perimeter, and an existing accumulation of waste within the recess having a collective top surface, the berm comprising:

• a reinforced portion having opposing inner and outer surfaces and comprising structural fill material and a plurality of reinforcing members disposed therein;
• and
• backfill material having an inner surface adjacent the inner surface of the reinforced portion, the backfill material being at least partially encapsulated by an impermeable membrane;
• wherein at least a portion of the berm sits on at least a portion of the edge surface of the landfill;
• wherein the inner surface of the reinforced portion and the adjacent inner surface of the backfill material are substantially non-planar, and
• wherein the inner surface of the reinforced portion and the adjacent inner surface of the backfill material each comprise a plurality of interlocking sections.
