Henry Pumadeq System

The Henry Pumadeq System is a cold fluid applied, seamless, monolithic waterproofing solution. It uses PUMA technology which combines Methyl Methacrylates with Polyurethanes for exceptional long-term performance and durability. Henry Pumadeq is a UV-resistant waterproofing system that sets in 30 minutes and can withstand traffic one hour after installation. The result is a more durable, flexible and longer-lasting waterproofing solution that provides superior low temperature crack bridging. Henry Pumadeq is an excellent choice when waterproofing plaza decks, protected membrane roofs, green roofs, and pedestrian and vehicular traffic coating applications.

  • PUMA technology is cold applied and requires no special installation equipment
  • Fast cure time speeds application; can be trafficked within one hour by other construction trades and machinery
  • Offers outstanding low-temperature crack bridging with no reinforcement required
  • Can be applied at low temperatures without affecting cure time
  • No detailing limitations such as laps, welds, seams, surface flashings or termination bars
  • Withstands constant water immersion; can be laid to zero pitch
  • Solvent free, no VOC
