Newton HydroCoat 104

Newton HydroCoat 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.

Newton HydroCoat 104 consists of Portland cement, specially treated quartz sand and a compound of active chemicals. Newton HydroCoat 104 is supplied in powdered form 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 Newton HydroCoat 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 HydroCoat 104. The speed of application and the low material application rate (1 kg/m2) makes Newton HydroCoat 104 a very low cost option for a large number of scenarios.

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

Product 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 Newton HydroCoat 104 remains vapour permeable, allowing the structure to ‘breath’.

  • 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.

Ancillary Products:

  • Newton HydroCoat 313-WP: For sealing of leaks prior to application of Newton HydroCoat 104.

  • Newton HydroCoat 203-RM: Rapid setting mortar for the repair of spalled or honeycombed concrete and surface cracks prior to the application of Newton HydroCoat 104. Can be used for the rapid creation of angle fillets.

Typical Applications:

 ✔ Pile Caps and Ring Beams

Pile caps and ring beams often support ground floor slabs and structural walls which are bearing with too much force for conventional membranes to deal with. Because Newton HydroCoat 104 is fully absorbed into the surface of the concrete an indestructible isolating membrane is formed that prevents moisture from the pile cap or ring beam from transferring to the floor slab or structural wall; and does so without creating a potential slip surface between the two building elements.

 ✔ Support Plinths

Where a steel or concrete column is to be supported from a plinth, conventional membranes are often not suitable due to the point loading transmitted through the column. Newton HydroCoat 104 will seal deep into the surface of the concrete to produce a membrane unaffected by the loading of the column.

 ✔ Sealing of Concrete Surfaces

Newton HydroCoat 104 will provide a dry surface to walls, rafts and slabs to car parks, garages and plant rooms, where a physical membrane is not suitable because of potential damage or where a physical membrane requires covering with a finish that is not required for the intended end use of the space.

 ✔ Isolation of Internal Walls from Moisture in the Kicker Joint

Newton HydroCoat 104 is the ideal product to prevent the migration of moisture to internal RC walls from kicker joints formed internally to the ground bearing raft. Once applied and correctly cured, Newton HydroCoat 104 forms a barrier to moisture within the surface of the kicker that cannot be damaged by the loading of the structural wall and one that provides a clean concrete to concrete interface of the two building elements so that slippage is not a concern.

 ✔ Isolation of Internal Walls from Moisture at the Abutment with Earth Retained Walls

Newton HydroCoat 104 creates a simple to apply barrier to prevent the migration of moisture to internal walls at the interface with the retained concrete walls. Newton 104 can be easily applied around reinforcing steel and dowel bars) to provide a continuous barrier to moisture that cannot be damaged by placement of the internal concrete wall. Reinforcing steel and dowel bars should then be coated with Newton HydroCoat 103 2K, lapped to the concrete, to provide a barrier against water tracking along the steel.

Substrate Suitability:

Concrete with reinforcement to BS EN 1992 (Eurocode 2) with crack mitigation to 0.3mm.

Surface Preparation:

All concrete to be treated with Newton HydroCoat 104 must be clean and have an open capillary system. Remove laitance, loose material, dust, dirt, oil, grease, general grime and contaminants by jet washing, grit blasting or scabbling.

Where there is evidence of fungus or mould growth, a suitable Fungicide should be used prior to application.

Spalled Concrete should be removed back to good concrete, treated with Newton HydroCoat 104 and filled flush with Newton HydroCoat 203-RM. If the reinforcing steel is exposed, abraid back to clean steel and coat with two coats of Newton HydroCoat 103 2K to prevent the steel from further corrosion.

Honeycombed Concrete should be removed back to good concrete, treated with Newton HydroCoat 104 and filled flush with Newton HydroCoat 203-RM. If the reinforcing steel is exposed, abraid back to the clean steel and coat with two coats of Newton HydroCoat 103 2K to prevent the steel from further corrosion.

Holes and Indentations in the concrete should be cut out with a dovetail cutter / router to a depth of at least 20mm. Treat with Newton HydroCoat 104 and fill flush with Newton HydroCoat 203-RM.

Cracks over 0.3mm should be cut out with a dovetail cutter / router to a depth of at least 20mm. Treat with Newton HydroCoat 104 and fill flush with Newton HydroCoat 203-RM. Cracks up to 0.3mm will be sealed by the Newton HydroCoat 104.

Leaking non-structural cracks should be cut out with a dovetail cutter / router to a depth of at least 20mm. Treat with Newton HydroCoat 104 and plugged with Newton HydroCoat 313-WP. Structural cracks should be repaired by specialists.

Where practical, cover the application with moist hessian and plastic sheeting during the 3-day curing period.

During the curing period the surface of the concrete treated with Newton HydroCoat 104 must be protected from frost, rain and standing water.

Where the treated concrete is to support a poured concrete structural element such as a supporting wall and the Newton HydroCoat 104 was applied as a slurry and has fully cured, the slurry residue must be removed by jet washing, sand blasting or scabbling to ensure a clean interface for the subsequent concrete placement.

Construction:

The construction should conform with current Building Regulations, British Standards and relevant Codes of Practice.

Concrete should be designed by a Structural Engineer to EN 1992 - Eurocode 2 and have a surface finish to Class of finish U3 as documented in ‘General Specification for Civil Engineering Works’ section 14: ‘Formwork and Finishes to Concrete’, namely a ‘Uniform, dense and smooth surface’ with float marks of no more than 3mm.

A U5 power floated finish with no float marks is also suitable but not required.

U1 (Abrupt irregularities permitted) or U2 (Tamp marks of up to 10mm) finishes are not suitable and should be avoided.

Application Methods:

Newton HydroCoat 104 seals the concrete by being absorbed to approximately 40mm into the surface via the capillaries and hairline cracks. Moisture is required for this to occur.

Green Concrete

The moisture still resident in the concrete acts as the carrier, allowing the active chemicals to be fully absorbed. Newton HydroCoat 104 can be applied as a powder prior to the initial set of the concrete (when you walk on the concrete you leave an imprint of approximately 10mm).

Concrete Cured Past Initial Set

If the concrete is no longer green and cured beyond the initial set, Newton HydroCoat 104 is mixed with water to create a slurry to allow the absorption into the concrete to take place.

Application - Dry Powder:

The application of Newton HydroCoat 104 must take place prior to initial set of the concrete.

  • Sieve the powder evenly onto the green concrete at 1 kg/m².

  • Trowel or power float into the surface of the concrete, again prior to initial set.

Application - Slurry:

The concrete surface should be dampened to nearly saturation point but not wet with standing water prior to application of Newton HydroCoat 104.

  • Create the slurry by pouring clean water into a suitable clean mixing vessel then slowly add the Newton HydroCoat 104 powder into the water whilst mixing with a slow speed mixing paddle until a consistency of thick oil paint is obtained. Approximately 9-10 litres of water is required per 25kg bag of Newton HydroCoat 104. Mixing ratio is 5 parts Newton 104 to 2 parts water by volume.

  • Apply the slurry in one coat at a dry powder weight of 1kg/m² with a masonry brush.

Coverage:

Newton HydroCoat 104 is applied in one coat at a coverage rate of 1.0 kg per m².

One 25kg bag of Newton HydroCoat 104 will treat approximately 25m².

Curing:

Newton HydroCoat 104 requires controlled curing. Once the Newton HydroCoat 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.
