HydroCoat 107 Elastic 2K – Cementitious Flexible Waterproofing Membrane 30kg
Newton HydroCoat 107 Elastic 2K is a two-component, cementitious, polymer-rich coating for the waterproofing and protection of concrete and masonry. Capable of withstanding heads of water pressure up to 10 bar of positive pressure and up to 1.5 bar to the negative side of the structure, HydroCoat 107 Elastic 2K is ideally suited to the waterproofing of reservoirs, tunnels, water tanks, earth-retaining structures and covered or buried decks, and is especially capable where the structure has both masonry and concrete elements where differential movement is expected.
When mixed, HydroCoat 107 Elastic 2K 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 and overhead situations. HydroCoat 107 Elastic 2K is reinforced over static joints and at details and changes of direction with HydroCoat 912-RT.
HydroCoat 107 Elastic 2K hydrates to form a durable, highly alkaline and permanently elastomeric coating which protects concrete and other substrates from water penetration, and also accommodates slight movement in cracks and at correctly specified movement joints. The product is also supported by BDA Agrément® BAB 18-026-P-A-UK and accepted by the NHBC as a suitable waterproofing system for Type A Waterproofing to Grades 1, 2 and 3 – BS 8102:2022 and to covered decks.
KEY BENEFITS
- Pre-packaged materials easily mixed on site
- Tough, flexible coating which maintains its elastomeric properties even when immersed
- Excellent adhesion to sound prepared concrete and masonry substrates, as well as steel
- Suitable for positive and negative waterproofing of earth-retaining structures as well as covered decks
- Dense matrix offers low permeability to water
- 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. Non-toxic when cured
TYPICAL APPLICATIONS
Waterproofing of:
- Podium decks, flat roofs, terraces and balconies
- Water-retaining structures such as water tanks and reservoirs
- Earth-retaining foundation walls to both the positive and negative side
- Internal concrete surfaces of walls and rafts or slabs to earth-retained structures such as habitable basements, car parks, plant rooms and lift-pits
SUITABLE SUBSTRATES
Correctly prepared substrates of:
- Concrete of at least 20kN
- Steel*
- Structural masonry/mortar
- Screed
SUITABLE SURFACES
Waterproofing of:
- Walls – Positive and Negative pressure
- Slab/raft – Negative pressure
- Soffit – Negative pressure
- Deck – Positive pressure
METHOD OF APPLICATION
- Squeegee
- Roller
- Airless Spray
- Pin Leveller
- Brush
- Trowel
*Bond to abraded steel is very good but not tested and so is suitable only for termination detailing
APPLICATION RATE
The membrane is applied to a total thickness of 2.0 mm, which requires an application rate of 3.2 kg/m².
Walls and soffits – Application is by two coats, each of 1.6 kg/m².
Horizontal surfaces – Application is by two coats, each of 1.6 kg/m2 or by a single coat of 3.2 kg/m².
At a thickness of 2.0 mm, a 30kg composite pack covers a total surface area of 9.4m².
