The Reality: All Concrete Cracks
First, the basics. All concrete basement walls crack. It’s very common for concrete to develop cracks, scaling, crazing and pitting. Because all concrete has the tendency to crack, and it’s not possible to produce completely crack-free concrete. Concrete expands and shrinks with changes in moisture and temperature. Consequently this shrinkage places stress on the concrete and to relieve that stress, the concrete cracks. The cracks will develop soon after the foundation is cast in place. The vast majority of cracks are not a sign of a structural defect with the foundation.
Structural Cracks in Concrete Basement Walls
While it is difficult to determine by looking at a basement wall crack if it is in fact a structural problem, there are a few rules to help guide you. Foundation cracks that run sideways (horizontally) are the most serious type of crack to look out for, as they can signal serious damage to your home’s foundation and structural integrity. As a result if the crack is over ½” wide there is a chance that it is a structural crack. Horizontal cracks are almost always a structural problem. Cracks that run on a severe diagonal. Especially those that start at an inside corner are usually a structural issue. In contrast diagonal cracks that start at the corner of a window or where the foundation “steps down”. And are under ½” most likely are not a structural issue.
If you are not sure if a crack is structural in nature. An engineer can be hired for a few hundred dollars to determine it for you. The engineer may use a crack stress gauge to help in determining if it is.
Signs of a structural crack
- >1/2″ in width
- The crack is horizontal
- The crack runs on a severe diagonal

Solving the Issue: Crack Repairs
An epoxy injection uses a two-part resin that when mixed becomes a very rigid, high strength material with tenacious bond to clean concrete surfaces. The epoxy is generally packaged in two parts that are mixed prior to application. The two parts consist of 1) an epoxy resin which is cross-linked with 2) a co-reactant or hardener. Epoxy injections are formulated based upon the performance requirements for the end product. When properly catalyzed and applied, epoxies produce a hard, chemical and solvent resistant finish. Cleaning of cracks is mandatory.
Some additional consideration for every application:
- Inspect concrete integrity, surface temperature, moisture and crack contamination. Epoxy injection resins will not cure properly when introduced into the presence of water inside or weeping of moisture out of crack.
- Identify and solve the cause of the crack
- Mechanically roughen length of concrete surface on each side of the crack to ensure epoxy paste bond.
Not All Cracks Need Attention
Fortunately, some cracks are more aesthetic in nature and won’t hurt if left untreated. Angular cracks often occur in the top 12-16 inches of brick walls laid directly on concrete foundations. Brick expansion during summer and the pushing of outer foundation corners cause angular cracks. You do not need to call in your crack repair specialist at Dry Effect if you notice angular cracks since apart from being relatively harmless, they will most likely occur every single year as temperatures rise.
In the upper levels of your house, cracks can appear above windows, doors, and archways. Although such cracks can be a sign of settlement, they are mostly simple relief joints. The size of these cracks will most likely change with temperature variations. You can, however, control these harmless eyesores by running a dehumidifier during summer and a humidifier in the winter.
Basement floor hairline cracks are quite common and mostly affect only the appearance of homes unless they widen to half an inch or more. Hairline cracks usually start at 90-degree offset corners and radiate into the room. Waiting for about a year for this type of crack to finish growing before you fill it in with hydraulic cement or urethane caulk is the best course of action.
How to Fix Foundation Cracks in Basement
Foundation cracks may be injected with materials to deal with the leaks. These injections are meant to fill the crack through the thickness of the concrete from the bottom of the foundation to the top. When a crack repair has been properly executed, there will be no more water that will come through that particular crack. It is often argued which material should be used, epoxy or polyurethane for a crack repair. The truth is it depends on the type of repair you are trying to achieve. Both epoxy and polyurethane have qualities that fit different repair needs.
