Re: Re: Basements in Ireland
Retrofitting a basement under an existing house can reduce the harmful effect of Radon gas. A properly constructed basement will act as a Radon barrier, whereas many older homes just have raised timer floors over earth that provide no protection.
While I am not doubting the ability of your company, I feel that it should be pointed out that retrofitting a house with a basement as a means of reducing radon is an outragously expensive solution to the problem. Also I feel that you are incorrect when you state that raised timber floors over earth provide no protection againat radon. If the void below the floorboards is ventilated then the radon will escape without collecting in your home. If, in the unlikely event that the space is not ventilated, opes can be made at plinth level very easily and inexpensively without the need for major works.
