Building regulations introduced in 1997 states that in a high radon area,
measures should be taken to protect the building from radon in the ground for example, in the case of a non complex building of normal design a fully sealed membrane of low permeability over the entire footprint of the building anda potential means of extracting radon gas from the substructure such as a sump. it is also recommended in the building regulations that new homes be tested for radon gas.
Surveys carried out by the radiological protection institute of Ireland show that a lot of new homes have high radon levels.
Many homes that are built to a high standard will have a radon barrier that is not fully sealed. One of the reasons is because the builder has no real way of checking it. To prove this we asked builders who kindly agreed to let us inspect 13 houses in a high radon area at random, with our new leak detection system 11 houses failed our test This was a mixture of houses of different types, the barriers installed was by builders using their own labour & professional barrier installation teams, all of the buildings inspected by our team were of the highest standards.
The leak detection system allows the builder to have the barrier checked before he pours the concrete sub-floor; this means the builder can rectify any problems before it is too late.
If you are to construct buildings safely for the occupants and minimise the potential routes for radon gas to enter the building you should consider using this system.The person paying for the construction of the building should ask the builder to use this system. Remember a fully sealed membrane will help to protect you and your loved ones
Q: so how do we check it?
A: we check it with a chemical that produces a large volume of dye
it is then pressurised through the pipe work that extends from the sump under the floor & terminates outside your house at footpath level. (The connection point for radon extraction)
Q: Will I be able to see the leak?
A: Yes you will because the dye allows everyone to see it with the naked eye.
Q: Where will you normally find a leak?
A: Most of the time a leak will occur in the cavity, or around service pipes, on certain occasions the dye will be visible where the barrier overlaps, other times where a trades man accidentally punctures it.
Any radon barrier checked by us & not damaged by other trades will carry the guarantee that should you still have a problem we shall provide a system to lower the radon levels ourselves at our own cost.
