Necoflex RAM™ Radon, Air & Moisture Protection System

Sealing the ground-floors and foundations of any new building is a critical and often challenging
phase of the construction process. With years of experience in this area, our technical
development team has worked hard to find a more reliable and cost-effective way of achieving this.

We believe they’ve found it!

BACKGROUND

Radon is excluded from buildings using passive and active systems. The provision of a suitable protection system, designed and installed by competent personnel will substantially reduce the risk of a building having radon activity above recommended target health levels.

Air Tightness of ground floors in buildings is necessary in order to prevent air entering from the soil below. It can help achieve an efficient Building Energy Rating (BER), since uncontrolled air movement negatively affects the heating and ventilation performance of a building. The provision of a suitable passive ground floor sealing system will significantly contribute to the overall air tightness of a new building.

Moisture and water ingress from the exterior of a building can lead to the deterioration of the fabric of the building and encourages the growth of mould which is harmful to human health. Ground water can penetrate from below, rising vertically by capillary action. The provision of a suitable sealing system in the foundation walls, ground floors and around service and structural penetrations will reduce the risk of moisture and water ingress.

The new Necoflex RAM™ Radon Air and Moisture Protection System effectively seals all three critical areas of ground-floors in buildings: -  Walls, Floors & Penetrations (Service and Structural), thereby ensuring the necessary degree of separation between the interior spaces of a building and the underlying soil. Now, for the first time, designers and builders can tailor their foundation sealing requirements to ensure the best possible protection for any given project.   

Until now the options for sealing ground-floors and foundations of new buildings have been limited. Typically a single membrane has been fitted across the entire footprint (including walls). Depending on the membrane type, this can often mean an over-specification in some areas of the construction, while other areas such as walls, corners and penetrations end up with considerably less than required to effectively exclude radon, air and moisture. Designers and builders can now solve these ground-floor sealing problems, in a cost effective manner, by dividing the task into

3 simple steps.....
                        

Step 1 - WALLS : Seal all masonry walls using the new Easi-Load™ Radon DPC and Corner Assembly (patent pending). The clever design of this new system means that awkward angles and upstands can be sealed quickly and effectively.

Step 2 - FLOORS : Seal the main floor area using any one of 5 Monarflex membranes. Simply choose the membrane best suited to the project site conditions (refer to Table 2 in NSAI Agrement Cert 09/0328). Installation is extremely fast since the membrane is rolled out like a carpet and taped to the Radon DPC.

Step 3 - PENETRATIONS : Seal all membrane penetrations using Easi-Pour™ Liquid Radon Sealant. This has been carefully developed to provide an effective radon, air and moisture seal around any shape. It is self-levelling and cures to form a custom-made seal in one "easy" pour!
