Newton 107F


Suitable for the waterproofing of reservoirs, tunnels, water tanks, earth-retaining structures and covered or buried decks.

Especially suited where the structure has both masonry and concrete elements where differential movement is expected.


A two-component, cementitious, polymer-rich coating for the waterproofing and protection of concrete and masonry. Capable of withstanding heads of water pressure to 10 bar, both positively and negatively.

When mixed, 107F is thixotropic to enable ease of application by brush or airless spray, providing an even finish with no sagging and excellent adhesion to prepared concrete and masonry substrates, even in vertical situations.

The product hydrates to form a durable, highly alkaline, permanently elastomeric coating which not only protects the concrete or other substrates from water penetration and carbon dioxide diffusion, but also accommodates movement in cracks and at movement joints.

The membrane is reinforced over static joints and at details and changes of direction with Newton 912-RT. For horizontal and vertical movement joints use Newton 106 FlexProof.

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

Features and benefits:

  • Accepted by the NHBC as a suitable waterproofing system for Type A Waterproofing to Grades 1, 2 and 3 - BS 8102: 2009 and to covered decks.
  • Pre-packaged materials easily mixed on site.
  • Tough, flexible coating which maintains its elastomeric properties even under immersed conditions to accommodate movement in cracks.
  • Good abrasion and very high resistance to freeze/ thaw cycles and de-icing salts.
  • Excellent adhesion to sound prepared concrete and masonry substrates, as well as steel.
  • Dense matrix offers low permeability to water, even at 10 bar pressure, and very high diffusion resistance to carbon dioxide gas.
  • Suitable for positive and negative waterproofing of earth-retaining structures as well as covered decks.
  • A 2 mm coat provides the equivalent to 135 mm of good quality concrete cover.
  • Can be applied to damp substrates in temperatures down to 5°C.
  • Water-based product, free from hazardous solvents, ideal for use in confined spaces. Non-toxic when cured.
  • Correctly prepared suitable substrates include concrete of at least 20 kN, steel, masonry and screed.
  • Can be applied via squeegee, roller, airless spray, pin leveller, brush or trowel.
  • CE marked and manufactured in accordance with EN 1504-2: 2004.
  • Guaranteed to resist weathering for up to ten years.


  • Ready for next coat: At 5°C: After 8 hours; at 10°C: After 7 hours; at 15°C: After 6 hours; at 20°C: After 5 hours; at 25°C: After 3 hours.
  • To be kept rain-free: At 5°C: For 5 hours; at 10°C: For 4 hours; at 15°C: For 3 hours; at 20°C: For 2.5 hours; at 25°C: For 2 hours.
  • Ready for temporary traffic/ protection boards: At 5°C: After 72 hours; at 10°C: After 72 hours; at 15°C: After 72 hours; at 20°C: After 48 hours; at 25°C: After 48 hours.
  • Ready for flood/ hosepipe test: After 7 days (at all temperatures).
  • Fully cured: After 28 days (at all temperatures).

General information


Smooth, matt grey coating.



Liquid: Milky white, Powder: Grey/ white


Cementitious flexible waterproofing membrane.


2 mm thick waterproof membrane.


30 kg in two parts - 10 kg Part A (Powder) and 20 kg Part B (Liquid).


Newton 107F is guaranteed to resist weathering for up to 10-years. The membrane is not UV colour stable and will slightly fade in colour over time, and it may take a few months for the colour to be consistent. Over time discolouration due to weathering may take place, but the membrane will be serviceable
