Proven durability for hundreds of years
Impermeable stability and durability is found in an incomparable moisture barrier that has been utilized for thousands of years and proven to last up to 500 years when properly applied. NELCO waterproofing expertise with lead membranes ensures the right size, thickness, and installation techniques. For enhanced safety and long-term reliability, lead is typically specified at 6 lb. or 8 lb. per square foot weight or equivalent to 3/32″ or 1/8″ thickness. This surface demands continuous integrity of the barrier for water tightness, so the process of lead burning (welding) is used to seal the seams and join the lead sheets.
