HydroCoat 104 Super

  • Crystal Clear Moisture Defense: HydroCoat 104 Super blocks capillaries and cracks, keeping concrete dry. Rapid application, low cost (1 kg/m2) for large areas.
  • Speedy, Cost-Effective Protection: HydroCoat 104 Super ensures a dry surface with quick application. Low cost (1 kg/m2) makes it ideal for various scenarios.
  • Concrete Harmony, No Slip: Penetrates deep, no physical membrane. Perfect for moisture control in pile caps, ring beams, and kicker joints.

Applied to the surface of concrete, HydroCoat 104 Super provides in-depth protection against the movement of moisture through the capillaries and hairline cracks.

The active chemicals within HydroCoat 104 Super combine with the free lime and moisture present within the capillaries to form insoluble crystalline complexes which effectively block the capillaries and any minor shrinkage cracks to prevent any further movement of moisture to provide a totally dry surface to the concrete.

Large areas can be quickly treated with HydroCoat 104 Super. The speed of application and the low material application rate (1 kg/m2) makes HydroCoat 104 Super a very low cost option for a large number of scenarios.

Because HydroCoat 104 Super penetrates deep into the concrete, it does not leave a physical membrane to the surface of the concrete element and so is completely unaffected by loadings imposed by further elements of the build. New concrete elements are placed ‘concrete to concrete’ with no potential for slip or separation as is the case with physical membranes. This makes HydroCoat 104 Super particularly useful as a means of isolating moisture within pile caps, ring beams and kicker joints to internal walls.

    Key Benefits

    • Ease of application – sprinkled on to new concrete and applied as a simple slurry to vertical and cured concrete.
    • Permeates deep into the concrete to form a barrier against moisture that cannot be damaged or punctured.
    • Loading capabilities only limited by the strength of the concrete.
    • No physical membrane – subsequent concrete placement is ‘concrete to concrete’.
    • Concrete treated with HydroCoat 104 Super remains vapour permeable, allowing the structure to ‘breathe’.
    • Easy to detail and specify as the concrete surface becomes the membrane.
    • Very cost effective alternative to conventional physical membranes.
    • Sealing of cracks up to 0.3mm resulting in dry concrete with less reinforcing steel requirement.

    Typical Applications
