Cold Applied Applications

Cold Applied Membrane Technologies

We recognize that hot rubberized asphalt may not be suitable for all projects and conditions. In such cases, Hydrotech has a variety of alternative products and solutions available.

HydroSeal Flashing & Deck Membrane
Is a high performace two-component component, fast-curing, polymethyl-methacrylate (PMMA) resin. HydroSeal Deck Membrane is combined with HydroSeal Catalyst and HydroSeal Fleece reinforcement to form a monolithic, reinforced waterproofing membrane for balconies or terraces, either exposed with appropriate HydroSeal Finish or concealed with hard set tiles or pavers. Flashing of all terminations and penetrations is accomplished with HydroSeal Flashing Membrane.

Features and Benefits

  • Versatile waterproofing solution that can address tricky penetration details with a clean look on the finished product.
  • Seamless application suitable for amenity, terrace, balcony, and pool deck areas. 
  • Slip-resistant coating for public tenant spaces ensuring safety and comfortability.  


HydroSeal 1K Membrane
Is a single component, low VOC, moisture-triggered, aliphatic polyurethane resin. It is a fully adhered, cold applied, highly elastic, and alkali resistant membrane designed for easy application in combination with HydroSeal 1K Epoxy Primer and a reinforcing layer of either HydroSeal 1K Fleece or HydroSeal 1K Fiber Reinforcement.

The HydroSeal 1K Membrane assembly is intended for exposed flashing details with Hydrotech’s Monolithic Membrane 6125 applications. It is particularly suitable for projects where the aesthetics of exposed base flashings might be a concern and/or where there are flashing conditions with tight clearances or irregular surfaces. HydroSeal 1K Membrane is available in standard grey and white colors.

Features and Benefits

  • Liquid applied membrane and flashings conform to virtually any shape and profile, effectively eliminating pitch pans, metal sleeves, etc.
  • 100% membrane and flashing reinforcement provides enhanced strength and durability throughout.
  • Direct bonding to the substrate prevents lateral water migration.
  • Exceptional adhesion to most common substrate materials including: concrete, brick, terra-cotta, limestone, wood, glass, copper, steel and aluminum.


Liquid Membrane 7000 (LM 7000)
Is a two-component, liquid-applied, asphalt-extended, aromatic polyurethane, waterproofing membrane that adheres to most substrates. This product is available in two grades: vertical (LM7000-V) and horizontal (LM7000-H). It is ANSI/NSF-61 approved for potable water. Liquid Membrane 7000 is intended for deck renovation applications, limited accessibility situations, potable water containment, and reservoirs. 

Features and Benefits

  • FM Approved
  • High Impact and Shear Resistance
  • High Durability and excellent Fatigue Strength
  • ANSI / NSF 61 Approved for potable water
