Cracks on Cinder Block Foundation Walls

Basement Foundation Waterproofing & Cinder Block Wall Repair

Everdry Waterproofing provides cinder block foundation walls and cinder block foundation repair to residents in Milwaukee, WI. Cinder block foundation walls can be particularly troublesome for homeowners, especially in the Milwaukee area. The combination of older homes and wet weather provides less than ideal conditions for dry, healthy foundations. Unfortunately, cinder block foundations are generally more delicate than poured concrete foundations because there are many more points of weakness within the wall. In advanced cases, the damage to the foundation walls is so bad that they begin bowing inward to the point of total collapse. These extreme situations are more common than we’d certainly like to see, so we recommend acting at the first signs of cracking.

Identifying Types of Cinder Block Foundation Damage

When it comes to identifying the varying types of cinder block foundation damage, there are several key types to be aware of, including stair-step mortar joint cracks and horizontal cracks. Below, we’ve gone into detail about these different cinder block foundation cracks.

Stair-Step Mortar Joint Cracks

Hairline stair-step cracks in older cinder block walls are probably the most common damage. This, along with the upcoming damage types, is primarily caused by external lateral soil pressure due to excess moisture or compromised foundation footing. If it is caught early, the wall can be reinforced using traditional means, such as beams and anchors, or with carbon fiber sheeting.

Horizontal Cracks

Thick, horizontal cracks that stretch across large portions of your basement walls generally point to serious structural issues. More often than not, these are accompanied by an inward bowing of the center portion of the walls. The structural integrity of your foundation is considered compromised at this point, and immediate service by a structural or waterproofing professional is highly recommended.

In both cases, you will almost certainly notice issues with unwanted moisture and pests entering the home through the soil behind the wall. For temporary relief, purchase hydraulic cement or masonry caulk from a home improvement store. These can be applied easily by the average do-it-yourselfer and may help keep moisture and pests out and heat in while you find a permanent solution.

When to Be Concerned About Cracks in Block Walls

If you notice a horizontal crack in your block walls, it is cause for immediate concern. A cracked cinder block foundation indicates underlying structural damage, especially if the crack widens or grows over time. No crack in your block walls is ideal; all should be investigated by a professional.
