Abstract

Flanges for use in basement waterproofing systems, and methods for their installation are disclosed. The flange may be installed at the interface between the foundation wall and footing at the sub-floor level. The flange comprises an angular portion extending from a vertical portion. The flange may also include a lip to facilitate installation, as well as one or more adhesive sections to enable the establishment of a closed system. The flange may be flexible and may include one or more tear-away features to allow the height of the flange to be altered. The flange may function in conjunction with a vapor barrier and other components of a waterproofing system, such as a drainage conduit and sump. The flange may be used in new installations as well as in retrofitting existing basements with a waterproofing system.

Claims

1. A basement waterproofing flange, comprising:

a vertical portion having a first distal end, a second distal end, and a first side between the first distal end and the second distal end;

an angular portion extending from the first distal end of the vertical portion, configured to create a space at a joint between a foundation wall and a foundation footing upon installation of the flange;

an adhesive section, positioned on the first side of the vertical portion, configured to create a closed system upon installation of the flange; and

a tear-away feature, positioned along the vertical portion, configured to facilitate altering a height of the flange.

2. The flange of claim 1, further comprising a lip extending from the second distal end of the vertical portion.

3. The flange of claim 1, wherein the adhesive section includes a plurality of adhesive strips positioned on the first side of the vertical portion.

4. The flange of claim 1, further comprising a plurality of tear-away features positioned along the vertical portion.

5. The flange of claim 1, wherein the flange is made from a polyvinyl chloride plastic material.

6. The flange of claim 1, wherein the flange is flexible.

7. The flange of claim 1, wherein the flange is 2 to 8 inches in height.

8. A basement waterproofing system, comprising:

a flange comprising a vertical portion, and an adhesive section positioned along a first side of the vertical portion, wherein the adhesive section is configured to be installed at a joint between a foundation wall and a foundation footing along a basement perimeter; and

a drainage conduit configured to convey groundwater along the basement perimeter for extraction.

9. The system of claim 8, further comprising a sump fluidly connected to the drainage conduit.

10. The system of claim 8, further comprising a vapor barrier disposed along the foundation wall.

11. The system of claim 10, wherein the adhesive section is coupled to the vapor barrier.

12. A process of waterproofing a basement, comprising:

providing a vapor barrier along an interior surface of a foundation wall;

sealing a flange against the vapor barrier along a perimeter of the basement at a joint between the foundation wall and a foundation footing to create a closed system; and

providing a drainage conduit in close proximity to the foundation footing to convey groundwater to a remote location for extraction.

13. The process of claim 12, wherein the step of sealing the flange involves utilizing an adhesive section positioned on the flange.

14. The process of claim 12, further comprising a step of applying a basement floor over the foundation footing and the drainage conduit.

15. The process of claim 12, further comprising a step of adjusting a height of the flange.

16. The process of claim 12, further comprising a step of fluidly connecting the drainage conduit to a sump.

17. A process of retrofitting a basement with a waterproofing system, comprising:

exposing a joint between a foundation wall and a foundation footing;

positioning a flange comprising an adhesive section at the joint along a perimeter of the basement; and

installing a drainage conduit in close proximity to the foundation footing along the basement perimeter.

18. The process of claim 17, wherein the step of positioning the flange at the joint comprises sliding the flange between the foundation wall and an interior basement wall.

19. The process of claim 18, wherein the step of sliding the flange involves utilizing a lip extending from a distal end of the flange.

20. The process of claim 17, further comprising a step of sealing the flange against the foundation wall with the adhesive section to create a closed system.

21. The process of claim 17, further comprising a step of adjusting a height of the flange.

22. The process of claim 17, further comprising a step of fluidly connecting the drainage conduit to a sump.
