Application

Suitable for use on concrete with reinforcement to BS EN 1992 (Eurocode 2) with crack mitigation to 0.3 mm. Typical application is on areas such as pile caps and ring beams, support plinths, and on internal walls.

Application methods:

  • Green concrete: The moisture still resident in the concrete acts as the carrier, allowing the active chemicals to be fully absorbed. Newton 104 can be applied as a powder prior to the initial set of the concrete.
  • Concrete cured past initial set: If the concrete is no longer green and cured beyond the initial set, Newton 104 is mixed with water to create a slurry to allow the absorption into the concrete to take place.

Newton 104 requires controlled curing. Once the Newton 104 begins to cure, moisten with a fine fog spray of water 2–3 times a day for three days. In hot or windy conditions, water spray should be applied more frequently.

Description

Newton 104 is applied to the surface of concrete to provide in-depth protection against the movement of moisture through the capillaries and hairline cracks within the concrete. It consists of Portland cement, specially treated quartz sand and a compound of active chemicals. Newton 104 is supplied in powdered form and is either sprinkled onto fresh concrete or is mixed with water as a carrier and brush or spray applied as slurry for application to fully cured or older concrete or vertical surfaces.

The active chemicals within Newton 104 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 Newton 104. The speed of application and the low material application rate (1 kg/m²) makes this product a very low cost option for various scenarios.

Because Newton 104 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 Newton 104 particularly useful as a means of isolating moisture within pile caps, ring beams and kicker joints to internal walls.

Surface preparation is required, as is protection after application - consult manufacturer for details.

Features and benefits:

  • Single component.
  • 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’.
  • Can be applied by airless spray for quicker application.
  • Concrete treated with Newton 104 remains vapour permeable, allowing the structure to breathe.
  • Easy to detail and specify as the concrete surface becomes the membrane.
  • Cost effective alternative to conventional physical membranes.
