WATERPROOFING WITH LEAD Whatever the lerm of construct.cn for a per manent buiJdmg, whether trad.t onal methods or the most advanced techniques in construction are used, protection against intrusion of water will be required. The general term "waterproof ing" however, implies more than just protection ag. '-nst weather since today's fc'Md.ng fech- r.

In H ese uses, sheet le;-d has pro-ed itself emme-lly suitable as one of the most prsct-cal forms of waterproef rg known. S.nce repairs, replacement and even "normal'* maintenance costs cn an accession rooftop irstk'absn enn be considerable, it stands to reason that if the same were required for a membrene bured be neath complex comb nations cf Ml and f.riyh. landscaping and other features, the costs could be catastrophic. These costs when added to the Original costs cf which they would certainty be a part, would make lead one of the cneaper means cf safely waterproofing valuable occu pied areas. Lead sheet, when property n<' j?!ed, wui last as tong as the most permanent of buddings. IMPERVIOUS TO MOISTURE Lead membranes and pans property installed provide an impe.meatie moisture barrier be tween the unit itself and the adjoining walls and Poors, a barner that is necessary f damage to structures or spaces below is to be avoided. Lead membranes cannot absorb moisture. Such is not the owe with non-metatlic membranes. o t DURABLE Sheet lead is extremely durable for such ap plications. Its u*c as a standard material in chemical plants handling many types of cor rosives attests to this fact. WORKABLE Sheet lead is extremely workable and can easily be made to conform to the surfaces on which the sheet lead is applied. Thus, voids between the lead and substrates, inherent in more rigid materials, are not left to settle out after the finish is installed. ADAPTABLE Sheet lead is extremely adaptable for use in ail sues or shapes. Sheet lead pans are easily and quickly installed for minimum size shower stalls, or m targe pools or areas. COST The cost of sheet lead is surprisingly low. The basic material cost has leveled off to a point where lead <s directly competitive with other quality materials. The ease of working lead reduces costs. PRECAUTION Green cement, concrete or mortar containing free Jlme may be corrosive to lead as it is to many'other common metals. It is therefore nec essary to coat Ihe lead with asphaitum to pro tect it during the curing singe of the cement. After the curing- the^asjtfpftum coating which provided the ne$ess4f? interim prok-hon is no longer important ,% * mm i 1 < LI A24246 o o OUTDOOR l'OOL3 AI-TD PLAATARS: Nc.
