PREPRUFE® Plus Provides Enhanced Waterproofing Performance

PREPRUFE® is the world's first waterproofing system specifically designed for under-slab and blind side applications.

More the 50 million square feet have been installed globally​, over the last 20+ years.

The PREPRUFE® Plus waterproofing system uses time-tested ADVANCED BOND TECHNOLOGY™ to provide a permanent, integral and continuous adhesive bond between the membrane and structural concrete.

"I've seen how (PREPRUFE® Plus) adheres to the concrete," said waterproofer Seth Higby. "You can't pry it off."

This bond is crucial for the prevention of lateral water migration and long-term waterproofing performance.

"Two weeks ago we kicked out 96 rolls in a day. Terminated, taped, everything, with a 20-man crew," said Kirk Himber, general supertintendent. "That's a new record for us."
