Radon barrier to DPC
Isocell Airstop Sealant SprintAIRSTOP-sealant “SPRINT” is a permanently flexible sealant used for filling gaps, Joining building elements and for bonding overlaps of vapour stops/barriers (also PEfoil) in dry constructions (except indoor swimming pools) and e.g. installation of windows and doors in accordance with standards: ÖNORM B 5320 and DIN 4108-7.
Isocell LF Bubi Primer
Area of application: Used to prime any porous surface such as sand and cement, plaster, concrete, EPS XPS, for application of all acrylic , butyl, bitumen and bitumen rubber tapes/adhesives.
Isocell Airstop Flex 100mm Used to adhere radon barrier to face of wall, Isocell Airstop Flex can be plastered over.
Radon Barriers need to be sealed to the DPC AT Damp course level, normally the dpc is left short with very little possibility of attaching the DPC to the radon barrier with tape alone, the solution is to use Isocell Sprint Adhesive sealant, applied generously onto the edge of the DPC and block work 10mm above and below the exposed edge of the DPC (to assist in application cut nozzle back and flatten out to achieve a wider dispersion ) , attach the radon barrier to the sprinted area with light but firm pressure . Apply Bubi primer to the wall surface above the Radon Barrier, allow the appropriate drying time and adhere the radon barrier to the face of the wall with 100 mm Isocell AIRSTOP Flex allowing at least a 40mm overlap of the tape in either direction.
