Reasons a new foundation can form cracks

Joseph Coupal - Sunday, February 14, 2010
  • The natural drying, hardening, and curing process of concrete creates vertical cracks on some basement walls as the substance dries and hardens - Depending on conditions during the installation of the foundation (temperature of the air, the density of the particulates, the temperature of the concrete, the humidity, and various other factors) concrete curing can take up to ten years. However, curing cracks typically occur in years 1-3. Many of these cracks will not pose a significant structural concern, but all foundation cracks should be monitored and taken seriously.
  • The concrete foundation is subject to severe stress when it’s first put in - To save time and money, foundations are usually back filled before the concrete has time to harden and settle. The impact upon the walls from the sudden pressure of back fill, -combined with impacts from rocks striking the outer foundation wall as the area is filled, can easily damage the wall. Until the construction is complete, the foundation is not protected from the temperature changes from the outside. This forces the concrete to expand and contract with all temperature changes.
  • Vibrating Rods - When concrete is mixed, vibrating rods are inserted that shake air bubbles in the mix to the top. If this is done improperly or too quickly, large air bubbles become part of the concrete in your foundation. These bubbles make poured concrete foundations weaker. To make matters worse, these air pockets expand and cool at different rates than the cement. This causes further deterioration and cracking of the cement.
  • Bad Mix - If too much water is mixed into the concrete, the concrete is weakened and much more subject to early flaking and spalling.

If Foundation Cracks Are Large

If a crack or cracks cover a significant portion of the foundation, or are too large to be filled properly with do it yourself compounds, you may have no other option than to hire an experienced repair service to address the issue. Always be sure that the company chosen is a reputable one and that they have received good reviews from friends, colleagues or family members that have used their services. The foundation of your home is very important to the structural stability of the home and if the foundation is compromised, the entire home could be in danger.

In many cases, the cracks in the concrete foundation will allow water to enter into the home, which can result in the growth of mold or fungi and can create health problems for the individuals in the home. If the mold is allowed to continue growing for a long period of time, it could result in a more hazardous situation and require a much more expensive clean up to be addressed.

The company that you choose should be polite, professional, and have experience in repairing concrete foundations and water leaks. To get the best value, the services of several different contractors should be compared and estimates should be obtained from each to compare prices and pros/cons. The cheapest price is not always the indication of the best value as some contractors will cut corners to lower their prices without lowering their profit. Most of the time, as we all know, you get what you pay for.

Leaky Basements - Why they Leak

From poured concrete foundations to monolithic, stone, block or tile basement walls, no basement is safe from water leaking through the basement walls, floor, and floor joist and then entering into your home.

Basements that leak water in through the joint where the floor and wall meet after a rain or snow melt are considered to be, the most common wet basements. More than 90% of the wet basements leak water from the walls and the joint where the floor and wall meet. Most basements rarely leak water up through the floor. Surface water collects and builds up in a pocket around the foundation causing hydrostatic pressure. Water then is forced through the joint where the floor and wall meet.

Is Basement Leaking or is it Condensation?

Joseph Coupal - Saturday, January 23, 2010

A simple quick test to determine if you are having a water leak through your foundation wall is to tape a piece of plastic or tin foil to the wall where you suspect water is coming in. Make sure you tape down all the sides, and then wait a few days. If beads of moisture have formed on the inside of the foil/plastic and between it and the wall, you have a leak coming through that wall. If there is moisture on the outside of the foil/plastic, your basement is suffering from a moisture problem.

Condensation is a result of too much moisture in the air. When there is too much moisture in your basement, the coolness of the walls pulls the moisture out of the air and the water droplets sit on the walls, metal, and other cool surfaces, creating a damp basement.
