In trying to understand the best approach when repairing a cracked foundation wall, it’s best to explore how and why foundation cracks occur.  Most foundation cracks are non-structural hairline cracks that are caused by concrete shrinking as it cures, improperly poured foundation walls or from some level of foundation settling over time.  Foundation cracks may be an aggravation when found in the basement of your home but in most cases, they don’t pose any real structural issue and can be repaired with relative ease.

Vertical foundation cracks run from the top to the bottom of a foundation wall which can make it easy to spot from the exterior of a building.  

When looking to have a foundation wall crack repaired, many people wonder if it should be fixed by injecting epoxy or polyurethane.  A few factors to keep in mind when deciding are; does your wall crack run vertically or horizontally, does it branch off into multiple veins, and how wide is the wall crack, is it more or less than a quarter of an inch wide?

For cracks that are wider than a quarter of an inch that do not pose any serious structural issues, it is best to inject an expanding waterproofing polyurethane foam.  It is also common practice to include either Kevlar staples or carbon fibre straps in order to give added strength and support to the foundation wall.

For cracks that are less than a quarter of an inch wide, it is best to inject an epoxy.  Epoxy does not expand but adds a structural element because of its strength and the way that it adheres to concrete.  For even more strength both Kevlar straps and/or carbon fibre straps can be added to this process as well.

Why Epoxy?

Due to epoxy’s significant ability to bond with concrete; when epoxy is used to fix a cracked foundation wall you are waterproofing your basement, structurally repairing a foundation crack , and at the same time preventing the possibility of future basement leaks from the crack repair area.

​​Polyurethane or Epoxy

​​Epoxy Crack Injections and Polyurethane Crack Injections are the best way to go when it comes to repairing foundation cracks in concrete foundations.

                        Crack Injections

Cracked concrete foundation walls can be repaired in order to stop water from even entering your home at all through the crack injection process. 
In many cases the most cost effective approach in repairing cracked foundation walls, is to inject a substance directly in to the crack from the inside of your home. This method provides a permanent repair the can be completed by a single technician in only a few hours.
In order to complete a foundation crack injection repair, a technician will apply a four stage process.

Radon gas, just what is it?  Where does it come from and what are its effects?  Radon gas is radioactive, naturally occurring and is created by the breakdown of uranium components in rock and soil.  An estimated 4 out of 5 homes in Canada contain detectible levels of Radon gas. Health Canada - What are the long term health effects of Radon Gas.

Radon gas has no colour, no scent and can only be detected by installing a long-term Radon test kit in your home, or by hiring a Radon measurement professional.  Health authorities warn that Radon gas exposer is the leading cause of lung cancer in non-smokers and responsible for 16% of all lung cancer related deaths each year in Canada.

Radon enters the home through several possible areas of entry.  Some of these are; foundation wall cracks, cracks around service pipes, beam pockets, construction joints, floor drains, window casements, support posts, sump pump baskets and even up through dirt floors.

When Radon gas finds a way into the home it effects the whole home.  During the cooler months of the year when all the windows of your home are closed, Radon gas can remain trapped in every room.  When results indicating higher then recommended or safe levels of Radon gas are detected, it is time to involve a professional. 

The most common and one of the most effective ways of stopping Radon gas from seeping into your home is with a foundation crack injection.

When Should I Get Carbon Fibre Straps or Kevlar Staples?

Structural cracks in concrete are caused by movement in the foundation, resulting in long-term creeping and fatiguing of concrete. Crack repair by injection alone may not be a permanent solution. Epoxy injection in structural crack repair is a suitable first phase, yet in cracks 1/4" or wider a second phase may be necessary. 

The repair process must be made permanent by addressing movement. The use of countersunk carbon-fibre staples provides the necessary reinforcement. By cross-stitching with carbon-fiber staples within the foundation crack area, creep and fatigue is eliminated and improves long-term performance of foundation walls. Carbon-fibre has been proven to be a safer and more effective product for structural reinforcement than steel.
