Process for the radon renovation of a building

摘要

The invention relates to a method for radon renovation of a building (1), wherein the air (3) from the adjacent to the building (3) soil (4) by means of a suction device (5), in particular a fan or blower, sucked in and expediently in the above-ground outer environment (6) of the building (1) is derived. First, at least two spaced, the building wall (7) penetrating holes (8) are generated, which establish a fluidic connection between the adjacent soil (4) and the interior of the building (1). Thereafter, a suction line (10) is passed through each bore (8). After that, air (3) from the soil (4) adjoining the building (1) is sucked into the building (1) through the suction lines (10) and expediently this air (3) then out of the building (1) into the above-ground outer Surroundings (6) blown out. According to the invention, shut-off valves (22) are provided in the suction lines (10) and the volume flows flowing through the suction lines (10) are adjusted by means of the shut-off valves (22).
