Cracks starting from the corner of windows, Very common as this is the Weakest point in the foundation. Cracks’ surfaces are sealed, Holes are Drilled, Ports are installed and Injection of Polyurethane can now begin to repair the crack.
Vertical cracks in Concrete foundations are common due to expansion/contraction/moisture level in soil or settling of foundation
Polyurethane injection in process from inside, filling the crack as it expands. Polyurethane expands when it comes in contact with water/moisture and fills the crack all the way to the outside. Filling any void there is on its way up.
If the crack is visible from the outside, We will seal the outside as well as the inside and then we inject from inside.
