Stoop Void Fill

Void Filling Under Residential Stoop, Alexandria, Virginia

Problem:

Large voids were visible around the perimeter of the customer’s front stoop.  Chipmunks were living under the porch, and the customer was concerned about the stoop cracking or dislodging from the wall.  The stoop was structurally supported by a foundation wall.

Solution:

Foam jacking crew sprayed high density polyurethane foam into stoop void to fill it.  This blocked the void so that animals can no longer enter it, glued the stoop to the underlying wall, and uniformly transferred the weight of the stoop to the underlying ground.  The crew also filled a small void under the sidewalk so help prevent it from settling.
