ABSTRACT:
An improved method and apparatus for waterproofing soil utilizing a flexible plastic sheet for providing a water barrier provides a system for readily detecting the presence of holes in the plastic material. The sheet includes a plastic layer which may be rendered electrically conductive by embedding conductive particles within it. The integrity of the sheet may then be monitored by establishing an electric field across the sheet and monitoring for sparks between the conductive plastic layer and a probe. Reliable and economical testing is possible, even in situation where electrical leak testing was not previously feasible.
