Kind Of Tile

Categories: DRAINAGE

When clay tile is used, it should be well burned. Some

manufacturers offer soft tile for sale, as the loss from warping and

cracking is less in case of insufficient burning. The claim may be made

that the efficiency of soft tile is greater than that of the hard tile

whose porosity has been destroyed. This is an error, as the water

enters the drain at the joints, and not through the walls of the tile.

Underdrainage should be permanent in its character, and it is essential

that every piece of tile be sound and well-burned.



Vitrified clay tile is good for drainage, but no better than common

clay hard-burned.



Round or octagonal tile is the most desirable because it can be turned

in laying to secure the best joints. Collars are not needed in ordinary

drainage.



Cement tile is coming into general use in regions having no good clay.

Its durability has not been tested, but there is no apparent reason

that it should not be a good substitute for clay.
