Newton CDM 503 - Basement Waterproofing Membrane for Waterproofing of Existing & New Build Basements

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. It consists of Portland cement, specially treated quartz sand and a compound of active chemicals. HydroCoat 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 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. 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 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.

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’.

A two-core drainage sheet consisting of a non-woven geotextile filter layer thermally welded to a water impermeable high-density polyethylene (HDPE) drainage membrane.

The product provides drainage and protection to the outside face of basement walls to sloping sites, preventing the build-up of water pressure and protecting the structure from aggressive water, chemicals and toxins, and provides mechanical protection only when used against the ‘Type A’ waterproofing where the site is not sloping and so where ground water removal is not viable or recommended.

Consult the manufacturer's literature for relevant installation information.

Features and benefits:

• Assists in moving water around and downhill of the structure to sloping sites to prevent water pressure from bearing against the structure.
• Resistant to all chemicals normally found in the ground and unaffected by soil, bacteria and fungi.
• Withstands stresses and movement acting as a slip membrane as the backfill settles.
• Allows for backfilling with excavated earth.
• Extremely strong material, minimising the risk of damage when backfilling even when no protection board is used.
• Very high compressive strength.
• Suspended soil particles (fines) are filtered out by the geotextile layer.
• Quick and easy to install with a range of ancillary fixing and installation products.
• CE marked, and manufactured in accordance with EN 13252: 2016.

A multipurpose silicone sealant primarily used with the NewLath 805 Mesh Membrane and Newtonite 803 Membranes - applied to the plug before fixing into the membrane, 801 Mastic seals the penetration and prevents bridging between the damp substrate and new internal surface.

Applied to the fixing plugs before they are fitted, Newtonite 801 Mastic serves so as to seal the penetration and stop the occurrence of a 'bridge' between the damp or stained substrate and the new internal surface. Newtonite 801 Mastic has a high resistance to both ageing and extremes of temperature, as well as achieving a high adhesive strength, without primer, on the majority of materials used in the building and engineering industries.
