Radona R802 is used for radon sealing at embedments in concrete walls and floors.

The seal is suitable for all types of piping, e.g. plastic, steel, cast iron, concrete etc., and is fitted onto the pipe for complete embedment . In some cases the ring can be used on corrugated plastic piping ( see fitting instructions).

The unique profile of the ring, together with the hose clip provides an effective seal between the pipe and concrete. This effective sealing is partly due to the ability of the hose clip to hold the rubber ring in close contact to the pipe during the concreting process.The flanges of the ring are effectively fastened in the concrete during the setting process.
