Homes – particularly homes built on Massachusetts’ rocky terrain – are almost never built on level ground… and it’s a requirement that the ground is excavated to allow for the cement foundation. This means that the excavators need to either remove or add a whole lotta dirt to make room for your home’s foundation.

How does one build a cement foundation? First, the footing is poured into a wooden form and then cement is poured into the wooden form. The cement is leveled off and – after just a few hours – the cement is dry and the wooden forms are removed. Then, the foundation is expected to carry the home’s weight once the construction of the house begins. An average home of 1,600 square feet weighs in at approximately 345,000 pounds. That’s over 172 tons!

What does that mean for your foundation? Cracks! Of course, there are going to be cracks in the foundation. When all that weight starts to settle in the ground and the foundation moves, weak points develop. These points are most often found around the basement windows or where the foundation wall might drop down to a lower level. These foundation cracks are actually called settlement cracks and they’re very common. But don’t be alarmed… they can be repaired.

But here’s where it gets interesting… did you know that concrete expands and contracts with the changes in temperature? That’s why a crack can’t be repaired by the average homeowner or the neighborhood handyman. When a New England Dry Basements technician is called out to repair a foundation crack, the first thing we see is layer after layer of hydraulic cement someone has put over the foundation crack in an attempt to stop the foundation leak. But hydraulic cement does not expand and contract! The concrete foundation expands and contracts but the hydraulic cement does not expand and contract along with it… causing another water leak in your basement

We repair foundation cracks professionally and guarantee our work with a full  10 – YEAR WARRANTY. Your repair will be made using our three step process. This process includes the use of a two-part thixotropic paste followed by a high pressure injection of hydrophobic polyurethane resin every 8” – 10” along the length of the crack. The system then utilizes a liquid rubber membrane as an additional water barrier. We’ve said it before and we’ll say it again… most foundation cracks can be repaired in less than a day.
