Abstract

A drainage tile made of plastic, of triangular cross-section (front to rear) flat on top, slightly angled on the bottom. A slot runs the length of the tile at the bottom, the purpose of which is to stop sedimentation build up and blockage which occurs in other types of drainage (clay tiles or flexible tube). The sections of tiles would be joined by tang and slot at each end inter-locking to ensure an even height. <IMAGE>
