Repairing Foundation Cracks

When faced with a cracked foundation, it can be tempting to immediately search for a fix. However, before delving into concrete crack injection solutions, it is important to examine the details of the crack in question. Consider the width and depth of the crack as well as whether it is dormant or actively spreading.

Appearance may also come into play, particularly if the foundation is visible from the street. In addition, it's crucial to determine whether or not you need to seal against pressure, as this will inform which products are best to use. Taking these factors into account will allow for a more targeted and effective repair.

What Causes Foundation Cracks?

Concrete cracking is a frequent cause of complaints from homeowners. Cracking can be the result of one or a combination of factors such as shrinkage, thermal contraction, settlement or applied pressures. Cracks can be unsightly and a source of water intrusion. This is where finding the source or cause of the cracking comes into play.

Cracks that occur before concrete is fully hardened are due to shrinkage caused by the loss of water in the concrete mix. This is known as plastic shrinkage cracking.

Settlement cracks generally develop around embeds or around openings. It is not uncommon to first see a crack at the corner of a door or window or even near a beam pocket. Settlement cracks generally result from insufficient consolidation, dry mixes or lack of adequate concrete coverage over reinforcing steel.

Structural cracks in residential foundations usually result from settlement or horizontal loading or pressures. These types of cracks are much more prevalent in block basement walls. Generally hydrostatic pressure from water in the soil is the culprit. As more and more water builds the soil starts moving downward and outward. This outward movement applies great pressure on the wall eventually causing cracks.

Diagonal wall cracks that extend nearly the height of the wall are often a good indication of settlement. If structural cracks are suspected you should contact a professional engineer immediately.

When to Use Foundation Crack Injection

Fine cracks may be sealed by injecting them with either a polyurethane grout or an epoxy resin. In recent years, epoxy resins have become the favored material, on dormant cracks, for this purpose and formulations are available which will penetrate cracks as fine as 0.1 mm in width, or less.

Epoxy grouts are widely used because:

  • They adhere strongly to both fresh and hardened concrete;
  • Formulations are available which will adhere to most surfaces and harden even under wet conditions
  • They have good mechanical strength and low shrinkage
  • They are resistant to a wide range of chemicals, including alkali’s

Epoxy grouts are normally injected under pressure. Nipples or injection points are fixed along the line of the crack and the surface is then sealed, on both sides of the cracked element. The epoxy is then injected under pressure, using specialized equipment. Once the epoxy hardens the repaired section often becomes stronger than original, hence the term concrete welding.

Wider cracks, i.e. those 1 mm or more in width, may also be sealed by injecting epoxy resin, particularly cracks on vertical surfaces. On horizontal surfaces it may be possible to simply pour the poly grout into the crack.

Other materials, such as polyurethane resins, have also been used satisfactorily to seal fine wall cracks. They can have lower viscosities than epoxies and, hence, can penetrate more easily. However, they generally do not achieve the same bond strengths.

Live cracks must be sealed with a flexible material, polyurethane, which can accommodate the movement in the crack. This is especially so when cyclic movements are anticipated. Flexible epoxy resins are available which will accommodate a small amount of movement but the more usual procedure is to choose a polyurethane - that remains flexible with wall movements.

As the technology of basement wall crack injection has grown the costs to perform this solution has decreased. Today’s crack injection professionals have very specialized equipment and specialized training which allows them to very quickly identify the best repair procedure and perform the injection at relatively low cost. There is no reason to wait any longer, the cracks will not fix themselves.

Foundation Crack : DIY or a Job for Professionals?

Homeowners take pride in taking care of their 

Injection

homes. They mow the lawn, wash the windows and gutters, and repaint every few years. So when a problem arises, they want to fix it as soon as possible. That's why many homeowners try to tackle home repairs on their own, rather than hiring a professional.

Foundation cracks are one type of repair that should be left to the experts. While it may seem like a simple fix, injection of concrete cracks requires specialized equipment and training. In addition, an improper injection can actually make the problem worse. So if you're considering DIY foundation crack injection, remember that it's not always as simple as it seems. You could end up doing more harm than good.
