1. A method for controlling fluid leakage through soil in a region comprising:

  • (a) sequentially passing over the region to dig a plurality of parallel, laterally spaced grooves in the surface;

    (b) removing the soil from a groove as it is created;

    (c) laying a strip of fluid impermeable sheet material over a groove during each pass, the strip being wider than the width of the groove; and

    (d) depositing soil dug from the groove onto the strip such that the latter is covered with soil except along one edge, the other edge of the strip overlying the uncovered edge of an adjacent strip laid down during a previous pass over the region, thereby establishing over the region a first layer of overlapping strips of sheet material covered with soil.
