Abstract

A radon removal system includes a slab forming part of a foundation of a building, a barrier layer laid under the slab, the barrier layer being vertically gas impermeable and horizontally gas permeable. A gas inlet in the sealed system provides a fluid connection for gas flowing from the barrier layer through a sealed system (for example a sump body with water inlet, sump pump and water outlet) to a gas outlet. A negative pressure generated by the sealed system brings gas from the barrier layer into the sealed system through the gas inlet and out of the sealed system through the gas outlet.

Claims

1. A radon removal system, comprising:

a slab forming part of a foundation of a building;

a barrier layer laid under the slab, the barrier layer being vertically gas impermeable and horizontally gas permeable;

a sealed system having a gas inlet providing a fluid connection to the sealed system for the gas collecting under the barrier layer and a gas outlet for removing gas from the sealed system, the sealed system generating a negative pressure for drawing gas from under the barrier layer through the gas inlet to the gas outlet.

2. The radon removal system of claim 1 in which the gas inlet comprises perforations in the sealed system.

3. The radon removal system of claim 1 in which the gas inlet comprises a pipe that extends under the barrier layer.

4. The radon removal system of claim 3 in which the pipe is a perforated pipe that extends under the foundation to a central area of the foundation.

7. The radon removal system of claim 1 in which the sealed system comprises a sump body and the sump body comprises a water inlet, sump pump and water outlet.

8. The radon removal system of claim 7 in which the sump body has an interior and window for allowing viewing of the interior of the sump body.

9. The radon removal system of claim 7 in which the sump body comprises a neck embedded in the slab with a gasket around the neck between the neck and the slab.

12. The radon removal system of claim 1 in which a blower in the sealed system is provided to generate, in operation, a generates negative pressure in the sealed system for drawing gas from under the barrier layer through the gas inlet to the gas outlet.

13. The radon removal system of claim 1 in which the gas outlet comprises a vent pipe extending from the sealed system to outside the building and the blower is within the vent pipe.

14. The radon removal system of claim 1 in which the barrier layer comprises a membrane.

15. The radon removal system of claim 14 in which the membrane comprises a dimpled underlayer.

16. The radon removal system of claim 15 further comprising a fabric layer beneath the dimpled underlayer.

5-6. -6. (canceled)

10-11. -11. (canceled)

17-25. -25. (canceled)

26. A radon removal system, comprising:

a slab forming part of a foundation of a building;

a pipe extending under the slab;

the pipe being connected to a vent through a sump defined by a container; and

the container having a neck embedded in the slab, the neck extending vertically with a gasket around the neck between the neck and the slab.

27. The radon removal system of claim 26 in which the vent has a blower for generating a negative pressure in the pipe

28. The radon removal system of claim 27 in which the vent comprises a vent pipe extending from the sump to outside the building and the blower is within the vent pipe.

29. The radon removal system of claim 26 in which the pipe is perforated pipe.

30. The radon removal system of claim 26 in which the pipe extends under the foundation to a central area of the foundation.

31. The radon removal system of claim 26 in which the sump comprises a water inlet, sump pump and water outlet.

32. The radon removal system of claim 26 in which the sump has an interior and window for allowing viewing of the interior of the sump.

33. The radon removal system of claim 26 in which the pipe comprises weeping tile.

34. The radon removal system of claim 26 in which the pipe comprises hard plastic.
