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. Additional information including details and specifications are available for download in the Resource Center.

Sikalastic® Rapid PMMA
Sikalastic Rapid PMMA is a two-component high-performance, rapid-setting, polymethyl methacrylate-based (PMMA) liquid resin. It can be used in both Flashing Applications (Sikalastic Rapid-724) and Roofing Applications (Sikalastic Rapid-723). Sikalastic Catalyst is added to the resin to activate the chemical curing process and used in conjunction with Sikalastic Fleece to form a monolithic, self-flashing and self-adhering reinforced waterproofing 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. 
  • Optional slip-resistant coating available for public tenant spaces ensuring safety and comfortability.
  • An unpigmented finish coat (which can be mixed with a color additive) is also available. Contact Hydrotech for standard and custom color options. 


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® 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 (LM 7000-V) and horizontal (LM 7000-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
