Newton HydroCoat 104 Super – Crystalline Waterproofing
Newton HydroCoat 104 Super is applied to the surface of concrete to provide in-depth protection against moisture movement through the capillaries and hairline cracks in the concrete. It consists of Portland cement, specially treated quartz sand and a compound of active chemicals. HydroCoat 104 Super is supplied as a powder and is either sprinkled onto fresh concrete or is mixed with water as a carrier and brush applied as a slurry for application to fully cured or older concrete or vertical surfaces.
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 onto 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
COVERAGE
HydroCoat 104 Super is applied in one coat at a coverage rate of 1.0 kg per m². One 25 kg bag of HydroCoat 104 Super will treat approximately 25 m².
