Cracks in Exterior of Foundation
The cracks in this foundation go all the way through the walls, indicating severe instability.
Closeup of DIY Fix Attempt
Here, you can see the remnants of what is likely a rubberized paint - this is often suggested by people who don't know any better as a way to seal wall cracks against water and reinforce weak points in the wall. But water is stronger and will eventually break through such attempts.
Visible Cracks Between Windows
It's very likely that whoever installed these basement windows was not familiar with below-grade work - that is, below the ground - which is why the wall with the windows is the one most affected by soil pressure.
Huge Wall Crack in Bowing Basement Wall
The breadth of the crack in this wall is insane - it's amazing that the wall is still standing. Note the evidence of some DIY attempt to seal it off from water, which clearly didn't work.
Wooden Beams Show Degree of Bowing Wall
These beams are installed floor to ceiling, but this one doesn't touch the joist or the subfloor, which shows how off-kilter the wall is.
Deep Excavation Needed for Sentry Seal
As shown by one of our crew members standing in the hole, quite a bit of excavation is needed in order to reach the bottom of the foundation.
SentrySeal Provides External Waterproofing
While we usually install waterproofing systems inside the basement, SentrySeal is one of our less common external methods. The membrane prevents water from entering through walls in the first place, which lessens the chance they'll be weakened and continue to bow.
