NEWTON 410 GEODRAIN - 1

NEWTON 41OGEODRAIN JOHN NEWTON Externally Applied Drainage Membrane Newton 410 Geodrain is a two-core drainage sheet consisting of a non-woven geotextile filter layer thermally welded to a water impermeable HDPE (High Density Polyethylene) drainage membrane. Newton 410 Geodrain provides outstanding drainage and protection to the outside face of basement walls, preventing the build-up of water pressure and protecting the structure from aggressive water, Prevents water pressure from bearing against the 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 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 TYPICAL APPLICATIONS As the drainage layer of an externally applied waterproofing system when used in conjunction with sheet applied or liquid applied external tanking Protection of the structure from aggressive chemicals in To prevent the build up of ground water to retaining Vertical Water Flow at 20kPa (l/m2's) 4.60 Service Temperature Range (°C) -40 to+80 Life Expectancy (Years) >50 STUDDED CORE Colour Black Material HDPE Vicat Softening Temperature (°C) 148 Horizontal Water Flow Newton 410 Geodrain is resistant to a wide range of chemicals, impervious to root penetration, rot-proof and unaffected by soil bacteria and fungi.

NEWTON 410 GEODRAIN Vertical Protective Drainage Membrane DATA SHEET NEW-BUILD WATERPROOFING DESIGN PRIMARY WATERPROOFING MEMBRANE Build new structures to the requirements of BS8102:2009. Further guidance is available in CIRIA Report 139 - Water Resisting Basements. Use Newton System 300 water-bars at construction joints as part of an effective multi-staged approach to the waterproofing. Newton 410 Geodrain is a drainage membrane, not a waterproofing membrane. Primary waterproofing of the structure should be achieved with one of the following products: Carry out a geotechnical survey to...

NEWTON 410 GEODRAIN - 3

NEWTON 410 GEODRAIN Vertical Protective Drainage Membrane • Backfill should be compacted every 600mm to prevent linear shear of the filter fabric from the drainage core if no protection board is used. Seal the Geotex fabric surrounding the Geopipe and clean stone to the filter fabric face of the Newton 410 Geodrain with Newton Waterseal tape, or alternatively carefully place the 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...
