This construction is composed of a split, salt-glazed clay covering is a fibrous tilling. This construction is durable andefficient, but is not easily installed around short-radius can be covered by means of elbows of the tile. Concrete tile, waterproofed, is sometimes used instead of salt-glazcd clay tile. Sectional covering may be substituted for thefilling, and should be waterproofed. The joints in the tile must bewater-tight. The underdrainage should be effective. The method shown hereis good, but it would probably be better to fill in with crushedstone up to the top of the tile.
