How do cracks in basement walls develop?
Most cracks are caused by uneven settling of the foundation. All foundations settle, but not all portions settle uniformly, which causes cracks to develop. Other factors, including improper concrete mix, premature back filling, uneven moisture around the foundation, and plumbing leaks, can all contribute to the appearance and severity of cracks.
Do cracks mean that my home is structurally unsound?
Most common foundation cracks pose no structural problems. The biggest issue is water leakage, which can damage finished basements and contribute to corrosion of the reinforcing steel inside the wall. If left unchecked, a small crack can grow larger and eventually pose a structural risk.
My home is a new construction. Why are cracks appearing so soon?
Houses settle the most when they are first built. Light cracking will typically develop in the first month, and more obvious foundation cracks within the first year.
Can I seal the crack by covering it with mortar?
Surface repairs will not permanently seal a crack. If the crack is leaking, water will find its way around, or even through, the mortar patching. The best way to permanently seal a crack is by injecting it with an epoxy polymer. This fills the full depth of the crack to prevent further erosion, and eliminates the effects of further foundation settlement.
Another company performed waterproofing work on my basement, and the final product was less-than satisfactory. How does Suburban Basement finish their work?
Many companies consider the example at left as their finished product. As you can see, it is less-than appealing. We always complete our work by making a flush surface that can be easily painted or finished. We also offer spray-coating, which adds a uniformly finished look to the entire basement wall.
