Excavation of Window Well:
Excavation is performed from the window well right down to the weeping tile. The weeping tile is located beside the house footing, below the level of the basement floor slab on the exterior.

Weeping Tile Flush Test:
A weeping tile test is performed to ensure that it is draining. It would not make sense to install a window well drain pipe down to a weeping tile drain that is non-functional.

Liquid Rubber is Applied:
Liquid rubber is applied to the exposed wall to seal it if there is a crack or other damage.

Dimpled Sheet Air-Gap Membrane:
If liquid rubber is needed (in the step above) we also provide a redundant protection layer with a dimpled sheet air-gap membrane which provides hydrostatic pressure relief.

PVC Drainout Installed:
A 4" rigid PVC drain pipe with drain grate is installed that extends from the top of the weeping tile or gravel drainage layer, to approximately 4" below the height of the window sill.

Window Well Installed:
A window well is then installed in the appropriate position and fastened to the wall with concrete screws to ensure it does not move out of place.

Backfill Added to the Dig::
The excavated area is backfilled with native soil, but not filled right to the top to allow for drainage gravel. Extra backfill is removed and disposed of by Basement Technologies®.

Drainage Gravel is Poured:
Gravel is poured inside the window well to facilitate drainage into the newly installed drain pipe. This allows any water to freely enter the drain pipe and leave the window well.
