<P>PROBLEM TO BE SOLVED: To provide a construction method of a low water permeable layer which can reduce influence on a peripheral structure and hardly causes variation in quality. Ž<P>SOLUTION: An aggregate 1 comprising bentonite-containing granules is spread to form a loosely packed aggregate S1 of the aggregate 1, and vibrations are applied to the loosely packed aggregate S1 to form a densely packed aggregate S2. Thereafter, granules 2 comprising the bentonite-containing granules are supplied from the upper side of the densely packed aggregate S2 to fill the granules 2 in gaps in the densely packed aggregate S2, and vibrations are applied to the densely packed aggregate S2.
