You may notice the foundation bowing inwards and water leaking into your basement. Both block and poured foundations can develop horizontal cracks.

Block foundations are prone to stair-step cracks. These types of cracks happen along mortar joints and pose a serious threat to the integrity of your basement foundation. There are two common causes of stair-step cracks:
Renco Tip: If you can put more than a quarter in the foundation crack call for a contractor for a professional inspection and repair options. While some mortar-based hairline cracks are common, anything larger is posing a threat.
Hairline cracks are common in new construction foundations across the country. They usually appear within one year and caused by the settling and drying of the new foundation. The good news is these cracks are usually cosmetic and can be repaired by DIY homeowners for $200 or professionals for $400-$600.
Renco Tip: If you purchased a new home and discover a hairline foundation cracks contact your home builder. Your warranty may cover the repair of the hairline crack. Make sure to take photos to document the crack and monitor progression.
Vertical cracks in your foundation wall are less serious than horizontal cracks and do not pose a structural threat. They are commonly found in poured foundations running straight up and down your wall. In Ottawa, vertical cracks are one of the most crack types found in basements. They are caused by the foundation settling overtime or the natural concrete curing process
Like vertical cracks, most diagonal foundation cracks do not pose a serious threat to the structural integrity of your foundation. They are found running a maximum 30 degrees of vertical and caused by the natural curing of the concrete foundation wall or settlement over time. The most common repair is epoxy crack injections, these crack repair costs range from $75 for DIY kits to $400 and up for professional crack repair.
Renco Tip: When you spot a diagonal crack snap a photo and document the date. If the crack is a hairline and a quarter cannot fit into it, you need not worry. Check back in 6 months, if the crack has continued to grow call a foundation professional for guidance.
Like hairline cracks, shrinkage foundation cracks happen when poured concrete foundations begin to dry out and lose moisture. New home builds are prone to shrinkage cracks within the first year. These cracks are often vertical and pose no structural threat to your foundation. The biggest risk is if you are in an area with high levels of Radon Gas that leak into your basement.
Renco Tip: If you are in a new home build, contact your builder about your home warranty. Shrinkage foundations may be covered. If not, snap a photo and document crack. If it grows or you discover more cracks investigate having an epoxy crack injection repair.
A non-structural foundation crack is one that does not pose a threat to the structure of the home, and typically only results in leaks during rainstorms or when snow is melting. Despite the lack of structural threat, water seeping into your basement is still a serious matter that requires attention.
Renco Tip: Concrete basement walls can have small cosmetic cracks due to the natural curing process. If your crack is between 1 to 2mm and runs vertical or diagonal it may be non-structural.
This type of crack is the result of foundation shrinkage due to water evaporating from the concrete. It would typically happen within the first month after a foundation is poured. The wetter the concrete mix is initially, the more shrinkage will happen, increasing the likelihood of cracks forming. The natural setting of the concrete can also lead to cracks.
In this case, epoxy is the material of choice for repairing the crack. Because the crack was initially caused by stress resulting from movement which can continue, epoxy alone is not generally enough to ensure the repair of the crack. Further reinforcement, in the form of carbon fiber countersunk staples or straps, is often necessary to ensure that the crack does not expand.

Applied Technologies manufactures polyurethanes used to stop water leaks. Concrete crack injection with polyurethane foam is the best way to stop a foundation wall crack leak. This is because the liquid urethane fills the entire foundation crack. Once inside the crack, it begins to foam and expand. The expanding foam completely fills it and prevents future water leaks. Water will now remain outside of the basement wall and not be able to penetrate into the interior.
A typical 8' foundation crack can be repaired in one hour. This is because there is no drilling or chiselling needed to widen the foundation crack. The low viscosity polyurethane can enter even hairline cracks with ease and stop your basement water leak.
To stop water from leaking into a concrete basement or concrete foundation crack, liquid urethane foam can be injected into it. On contact with water, the liquid urethane foams and expands inside the crack.
Concrete basement crack repair by urethane injection entirely fills the crack. Not only from the bottom to the top, but the entire width of the foundation wall. The water stays on the outside of the foundation and the basement contents are kept safe. The foam created is a closed-cell structure that will not allow water to work its way through the basement crack. The finished foam bonds tightly to the surrounding concrete to ensure that water does not push the foam out of the foundation crack. Once the urethane has foamed and expanded inside the foundation crack, water cannot leak into the basement again.
In comparison, a patch repair using hydraulic cement is much less reliable. Hydraulic cement must have the crack chiseled out into a vee-notch. This is a long and messy process. The chiseled out notch is only a few inches deep. The hydraulic cement cannot be placed into the entire width of the concrete wall. Therefore, water still gets into the basement crack from the outside. Over time salts develop which break the bond between the hydraulic cement and the existing concrete foundation. This allows water to leak again into the basement.
Concrete basement and foundation crack repair is done from the inside of the basement. The home's outside landscaping does not have to be removed and the foundation excavated for the leak repair. Also, there is no drilling or chiseling to perform a foundation crack leak repair using Applied Technologies' products. The concrete basement crack is filled entirely by the concrete crack injection repair material. This stops water from leaking into a basement and keeps the possessions dry.
Applied Technologies manufactures a full line of concrete foundation and basement crack repair materials and foundation crack repair equipment. These products will stop your foundation and basement leaks and keep your basement dry and clean.

The Basement is the one place on the Map in which the presence of The Entity can be felt the most, which is underlined with eerie sounds coming from beyond the basement walls and red lights shining through cracks in them.
To repair both floor cracks and cove seepage, the secret is to alleviate the hydrostatic pressure by giving ground water somewhere else to go. This is accomplished by installing interior drain tile, a system of perforated pipe installed under the basement floor.
The best way to repair a wall crack permanently is to inject it from the interior with expanding polyurethane. The polyurethane fills and seals the crack out to the soil and stays flexible when cured to prevent minor foundation movement from re-opening the crack. 2ff7e9595c
