Onr of t!r riiirtt, wmt, and no*t widely used water-proofing mrthodt it lie uv of lead shower pans. The tpreifiration on the following page pro* vidrd therefore to assist those wrho who to take ad* vantage of lead's outstanding waterproofing qualities. Sheet lead ran also be used to advantage in the waterproofing nf areas other than shower stalk or moms. Lrad safe pans under soda fountains, krtchem, and other places where leakage or spillage may occur, will preside the same high degree of waterproofing that is expected of lead shower pans. In general, the rame method of installation as outlined in the specs* firatson for lead shower pans should be followed. IMPERVIOUS TO MOISTUKE Lead shower and safe pam properly installed provide an impermeable moisture hjrnrf between the unit itself and the ad joining walk and floors* a barrier that is necessary if damage to beams, joius, studs or decorated surfaces is to be avoided Lead pam cannot absorb moisture. Such is not the case with noo-metallic pam. DURABLE Sheet lrad is rxtrmw-ly durable for surh applications. Its use as a standard material in chem ical plants handling man)' types of romwm attests to this fart. WORKABLE Short lead *f extremely workable and can easily he made to conform to the surfaces on whirh the sheet load pan is applied Thus, voids hetwrrn tlx* lead pan and flooring, inhrrrnt in more rigid materials, are not left to settle out after the tile floor is installed. causing the tUr to crack and buckle. ADAPTABLE Sheet lrad is extremely adaptable for use in all sirr or shape shower stalls or rooms. Sheet lead pans are cavils and qwi< lh installed for minimuni sire dtower stalls, or in lar^e rooms 01 areas. CQST The < r.st of sheet lead showrf and safe pam is vurjriinrh km.
