<p>The original composition of tile drainage in the 19th century was ceramic tiles of fired clay, similar to terracotta pipes but not always shaped as pipes. Today, modern materials such as HDPE and PVC tubing denominated 'tile line' are commonly used, although precast concrete and ceramic tiles are still used.</p> Signup and view all the answers

<p>Tile drainage in agricultural fields removes excess sub-surface water to allow sufficient air space within the soil, proper cultivation, and access by heavy machinery to tend and harvest crops. It is often considered the most effective means of draining subsurface water due to its ability to function in the same mode as the original system.</p> Signup and view all the answers
