New Product Aims at Foiling Leaky Basements
After extensive research and development, Owens-Corning Fiberglas Corp. announced it has developed what is believed to be the first basement waterproofing product for new home construction. Called Tuff-N-Dri, the product is a polymer-modified asphalt composition that, unlike damp-proofing products, stretches to bridge basement wall cracks, virtually eliminating leaks and the costly repairs they require. It is the only product of its kind supported by a certified waterproofing contractor program and available with a warranty, Owens-Corning said.
"Our research shows that leaky basements are a major problem for homeowners and homebuilders alike" said Dennis Modrich, manager of Owens-Corning's Protective Coatings Division. "We found that fifty-nine percent of American households have leaky basements, and for every new basement that leaks there's a builder who loses about $3,000 on the callback to repair it. If the sales contract has expired, then it's the homeowner who suffers. He or she will have to foot expensive repair bills, never knowing when another leak might develop."
# Strength and Elasticity
In response to these findings, Owens-Corning said it spent two years developing Tuff-N-Dri, that, when sprayed on concrete block or poured concrete basement walls at a thickness of 35-40 mils under laboratory testing, can withstand an 8 ft. head of water. If cracks should develop in those walls, the coating, unlike commonly-used damp-proofing products, will stretch to bridge the cracks, thus preventing leakage and consequent water damage, Owens-Corning said. "It offers true waterproofing, not just damp-proofing," according to Modrich.
He added that the product can be used on basements in virtually any type of soil; acids, bases and salts have no effect on its flexibility and elongation. Nor will it degrade when confronted with mold and bacterial attack, Modrich said.
Because of the spray-on process, a two-man crew can apply more than 1,500 sq. ft. of the product per hour-fast enough to keep most projects on or ahead of schedule, according to Modrich.
