Newton CDM 508R RADON is a high quality Cavity Drain Waterproofing Membrane for use within Newton System 500, Newton's internally applied Waterproofing System that includes Newton CDM Drainage and Pumping CDM Systems.
Newton CDM 508R is suitable for the waterproofing of earth retained walls, vaulted soffits and floors and is guaranteed against deterioration for 30 years, with a life expectancy of the design life of the building (DIN 9001:2000).
Newton CDM 508R is inert and, therefore, non-polluting to drinking water, highly resistant to water, alkalines, saline solutions and organic acids, and not affected by minerals and hydrocarbons. It is also rot-proof, and resistant to bacteria, fungi and other small organisms. Newton CDM 508R also exhibits high compressive loading stability.
Does not require extensive and damaging preparation to the wall surface
Speed of installation
Provides vapour control when used with humidity control systems and is capable of delivering an environment to all levels within a Grade 3 environment to BS 8102:2009
Independently certified as a barrier to hydrocarbon gases, radon and methane
Resistant to rot, chemically aggressive groundwater, acids and alkalines, efflorescent salts and hydrocarbon contamination
Newton CDM 508R RADON Membrane can be installed over a wide range of substrates in varying situations - walls, floors, ceilings, soffits, etc. However, before the system is installed, the area must be assessed to determine what preparation is required:
All timber and other organic material must be removed to prevent risk of fungal or bacterial growth behind the System, e.g. skirting boards, timber plates, old wallpaper etc. If evidence of rot exists, this must be dealt with by a specialist contractor prior to installation of the system (See our Woodworm & Dry Rot Control Products). If any mould, etc. exists, this should be cleaned off and the area sterilised with a Fungicidal Wash.
If the walls are uneven or areas have deteriorated, any large depressions should be levelled and made good to ensure a solid fixing
When assessing floor applications, consideration should be given to the type of finish that is required. The floor must be cleared of oil, loose material and any sharp protrusions and should be made level. Any holes or severe depressions should be filled. When a timber floor is preferred, then more consideration should be given to achieve a flat substrate prior to laying the membrane. This will relieve any undue movement when fitting the floor covering
The design of the drainage system should be agreed, implemented and tested before covering by the membrane. The exception to this is where Newton CDM Basedrain is sat above the slab or raft. Flood tests should be made to check the slab or raft is flat and level prior to the installation of the Newton CDM Basedrain, but the system can only be fully tested once the floor membrane and some form of resistance to water pressure is placed above the membrane such as temporary boards with bags of ballast or sand placed above, or the finished floor covering
When fixing the system to flat soffits you must ensure that there is a fall to create proper drainage and prevent ponding. Any sagging of the membrane should not be great enough for ponding to take place
