Types of cracks:

Horizontal –

Horizontal cracks are formed typically within the grout lines of the concrete block walls that run horizontally across the wall. Generally, the cause of these cracks is from hydrostatic pressure being pushed from the exterior wall. It is common, in Wisconsin, to have dense soil/clay that surrounds the homes foundation. This causes water retention on the exterior foundation walls. Not only does this add pressure to the walls but when we go through a freeze in the winter that water on the exterior freezes and expands. Over time the walls succumb to the pressure and begin to crack.

Vertical –

Vertical cracks are formed from top to bottom of the wall. They can form in block or poured walls. Typically, these can be caused by settlement of the home or exterior pressure.

Step –

Step cracks are formed in block concrete walls along the grout lines. They start at the top portion of the wall and continue down making a “step” formation. Causes of these are like the cases above.

Shear –

Shear cracks are formed when blocks or sections are actually separating and pulling away from each other.

Is it serious?

The severity of the crack all depends on how much deflection/movement is occurring on the wall due to these pressures. All our diagnosis is backed up by engineering standards which follows municipal code. When we perform an analysis/inspection we take you through the measurement process and explain what is happening with your walls.

The repair:

Based on the severity of your structural problems our method of repair is by means of steel bracing. We install steel support columns that anchor to your house joists (at the top) and either through the floor and into the footing or directly on top of the footing (at the base). Anchoring the steel supports directly on to the footing is only done when an interior drain tile repair is done at the same time. All steel sizing and spacing is backed up by engineering standards and municipal building codes.

Excavation:

As per engineering standards: if wall has bowed-in to the point that it can not just be repaired by supporting it from the interior, it would need to be corrected or straightened. In these scenarios: we excavate the exterior of the wall down to the footing, hydraulically push the wall back as close to plumb as possible, and then install new interior steel supports to ensure no future movement occurs.
