Studded 6mm polypropylene membrane with bonded Newton Geotex filter fabric to the front face of the studs for external drained cavity protection to retaining walls. Newton Geodrain must be used as a drainage layer diverting and filtering ground water to an external maintainable land drain cited adjacent to the bottom footing levels of the structure.
Newton Geodrain should always be used as part of a designed and maintainable water management solution. The perforated drainage pipe should have jetting eyes included at all changes of direction and should terminate into safe drainage only. Note: Any form of drainage that can ‘back-up’ is not safe.
A common mistake is for the system to drain directly to the storm water drainage system, but when this backs-up in periods of heavy and sustained rainfall, the water from the ground drainage system has nowhere to go resulting in a rise of water around the structure.Product Data Sheets
