ABSTRACT:
A method and apparatus forming a subterranean barrier wall that is substantially impervious to liquids. The barrier wall and method of forming the same comprises interlocking a plurality of sheet piles. Each sheet pile has interlocking edges that form a sealed joint. The interlocking edges consist of two semi-circular portions, a first semi-circular groove and a first radial edge, and a quarter-circular part, a second radial edge. Interlocking the sheet piles by a first inner locking edge, a second interlocking edge and an outer locking edge at the interlocking edges forms a barrier wall forming a substantially moisture-impervious seal.
