Abstract

A sump system for use in basement waterproofing systems. A sump liner may be generally rectangular in geometry, and may include two side elements with apertures to exchange groundwater while blocking debris. An adjustable inlet may be provided in another side element to fluidly connect other elements of a basement waterproofing system to the sump liner. The sump liner may further include a base configured to provide a built-in stand for a sump pump. The pump stand may contain a lip with notches to allow debris to fall and collect in a trough around a periphery of the base. The base may further provide an underside cavity for accommodating an obstruction in the floor of a sump hole. A removable lid may facilitate access to the sump liner interior, and may contain a break-away feature to accommodate discharge piping, as well as a groove to lodge a pump power cord. The sump liner may be strategically oriented within the sump hole to protect the basement foundation from erosion.

Claims

1. A basement sump liner, comprising:

a housing defining a chamber constructed and arranged to collect groundwater for extraction, the housing having a base with a top surface defining a bottom of the chamber and a bottom surface defining a cavity.

2. The sump liner of claim 1, wherein the base comprises an integral pump stand extending into the chamber.

3. The sump liner of claim 2, wherein the base defines a trough within the chamber along a periphery of the pump stand.

4. The sump liner of claim 2, wherein the pump stand comprises a pump shelf.

5. The sump liner of claim 2, wherein the pump stand comprises a lip formed along a periphery of the pump shelf.

6. The sump liner of claim 5, wherein the lip defines a plurality of notches.

7. The sump liner of claim 1, wherein the base is substantially rectangular in geometry.

8. The sump liner of claim 1, wherein at least a first side element of the housing comprises a substantially solid surface.

9. The sump liner of claim 8, wherein the first side element of the housing comprises an inlet to facilitate fluidly connecting the sump liner to a basement waterproofing system component.

10. The sump liner of claim 9, wherein the first side element of the housing comprises a knockout feature for forming the inlet.

11. The sump liner of claim 9, wherein the inlet is adjustable.

12. The sump liner of claim 8, wherein at least a second side element of the housing defines a plurality of apertures.

13. The sump liner of claim 1, further comprising a detachable lid.

14. The sump liner of claim 13, wherein the lid comprises a break-away feature.

15. The sump liner of claim 13, wherein the lid defines a groove at a point along its perimeter.

16. The sump liner of claim 13, wherein the lid comprises a removable plug.

17. The sump liner of claim 12, wherein the first side element and the second side element are removably attached to the base.

18. The sump liner of claim 1, wherein the sump liner is about 18 to 20 inches deep.

19. The sump liner of claim 18, wherein the cavity is about two inches deep.

20. The sump liner of claim 2, wherein the base comprises a support structure within the cavity.

21. A sump kit, comprising:

a sump liner having a chamber constructed and arranged to collect groundwater for extraction, the sump liner having at least one detachable side element with a substantially solid surface.

22. The kit of claim 21, wherein the sump liner comprises a detachable base with a top surface defining a bottom of the chamber and a bottom surface defining a cavity.

23. The kit of claim 22, wherein the detachable base comprises an integral sump stand.

24. The kit of claim 23, further comprising a sump pump.

25. The kit of claim 21, wherein the sump liner further comprises a removable lid having a break-away feature.

26. The kit of claim 21, further comprising discharge piping to facilitate groundwater extraction by a sump pump.

27. The kit of claim 21, further comprising a slidable cover constructed and arranged over an opening in the housing to facilitate securing a basement waterproofing system component to an inlet of the sump liner.

28. A method of waterproofing a basement, comprising:

providing a sump liner having a chamber constructed and arranged to collect groundwater for extraction, the sump liner having a first side element with a substantially solid surface; and

positioning the sump liner within a sump hole such that the first side element with a substantially solid surface is proximate to a foundation wall of the basement.

29. The method of claim 28, wherein positioning the sump liner within the sump hole comprises positioning the sump liner in a corner of the basement.

30. The method of claim 28, further comprising fluidly connecting the sump liner to a drainage conduit.

31. The method of claim 30, wherein fluidly connecting the sump liner to the drainage conduit comprises adjusting a height of an inlet of the sump liner.

32. The method of claim 28, wherein the sump liner includes a second side element having a plurality of apertures, and wherein the method further includes positioning the second side element opposite the first side element.
