Newton 410 Geodrain provides outstanding 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.
Prevents water pressure from bearing against the structure
Resistant to all chemicals normally found in the ground
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.
Newton MultiPlugs: For Fixing the Membrane to the Substrate.
Newton Waterseal Tape: Provides a double-sided waterproof seal when joining two parts of the Membrane together.
Newton GeoStrip Profile: Used at the Top Edge of the Membrane to prevent debris and back-fill from entering the cavity between the drainage core and the filter fabric.
Newton 403 Hydrobond: A very high performance composite sheet membrane which can be used for Primary Waterproofing of the Structure.
As the drainage layer of an externally applied waterproofing system to sloping sites when used in conjunction with sheet applied or liquid applied external tanking membrane to BS 8102:2009.
Protection of the structure from aggressive chemicals in the ground water.
To prevent the build up of ground water to retaining walls.
Build new structures to the requirements of BS 8102:2009. Further guidance is available in CIRIA Report 139 - Water Resisting Basements.
Use Waterbars at construction joints as part of an effective multi-staged approach to the waterproofing.
Carry out a geotechnical survey to evaluate soil characteristics and groundwater conditions in accordance with BS 8004. Great care should be taken when considering waterproofing that requires the permanent removal of the ground water to be effective. See BS 8102:2009 Section 5 for further guidance.
When used as a drainage membrane, Newton 410 Geodrain should only be used to sloping sites where ground water is diverted around and drained away safely downhill of the structure.
The land drain or perforated pipe to the base of an externally applied drainage membrane should be maintainable and graded to an open outlet below the level of the lowest slab. If risk of surcharge exists a pumped back flow protection device should be used. See BS 8102:2009 Section 6.4 for further information.
Land drains or perforated pipes should be maintainable. Include accessible jetting ports at regular intervals with at least one jetting port to each elevation.
Apply a Waterproofing Membrane (i.e Newton 403 HydroBond) to walls in accordance with the product data sheets. If Newton 403 HydroBond has been applied below the raft, link the raft and wall membrane to provide continuous waterproofing.
Apply Newton 410 Geodrain horizontally. The membrane is held to the wall by the back-fill. Do not use Newton MultiPlug fixings through the drainage layer as this will also perforate the waterproofing membrane. Use the MultiPlugs as a final fix to the top of the installation ensuring that this is above external ground level
Using temporary means to hold the membrane in place whilst backfilling, overlap subsequent sheets of Newton 410 Geodrain, ensuring that the filter fabric of the next sheet overlaps the previous studded core - a section of filter fabric is separated from the drainage core for this purpose.
Seal the edges of sheets using the 60mm flange at the edge of each sheet using Newton Waterseal Tape.
Place a slotted drain to the base of the foundation so that the top of the drain is below the top of the internal slab level. Place the drain within a bed of clean graded 20mm stone surrounded by a sheet of Geotextile filter fabric ensuring that enough Geotextile is available to lap to the Newton 410 Geodrain to give continuity of the filter fabric.
NOTE: If Newton 410 Geodrain is used below the raft also, the slotted pipe will need to be lowered so it is below the horizontal membrane.
Ensure the slotted pipe drains freely to a safe collection point that is downhill of the structure.
Place the Newton Geotex filter fabric to the face of the Newton 410 so that it is held in place by the back-fill.
Use Newton GeoStrip to the top edge of the membrane to prevent debris and back-fill from entering the cavity between the drainage core and the filter fabric
Carefully back-fill the excavation. If graded stone is used, a protection board is not required but the stone should be placed in controlled layers of no more than 600mm so as to prevent slump to the membrane. If the removed soil is re-used, ensure that it does not contain sharp stones and ensure that the soil is compacted every 600mm. If sharp stones exist within the re-used soil a protection board will be required.
Lay Newton 410 Geodrain in adjoining strips above the hard-core. Sand blinding is not required. Extend Newton 410 Geodrain past the footprint of the raft by 500mm and continue to the slotted drain surrounded in clean graded stone. Overlap and tape sheets with Newton Waterseal Tape.
The Waterproofing Membrane (i.e Newton 403 HydroBond) should be laid above the Newton 410 Geodrain as the primary waterproofing membrane, prior to the placing of the concrete raft.
Newton 410 Geodrain is a drainage membrane, not a waterproofing membrane. Waterproofing of the structure should be achieved with a Primary Waterproofing Membrane, such as:
Newton 403 HydroBond, a very high performance composite sheet membrane.
A suitable liquid applied waterproofing membrane.
Newton 410 Geodrain should not be used to de-water permanently high water levels. See BS 8102:2009 Section 5 for further guidance.
Backfill should be compacted every 600mm to prevent linear shear of the filter fabric from the drainage core if no protection board is used
Do not fix through the waterproofing membrane to fix the drainage membrane
