Basement Waterproofing FAQs, answered by experts

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.
