"Concrete Unlimited installed a septic tank and septic bed, trenched and installed a long water line, removed and hauled stumps, made log decks, cleared slash, graded and prepped our cabin site, artfully placed rocks and boulders that were uncovered in the process. Our remote lot had many constraints and he navigated through them beautifully -- and on time. My husband has seen heavy landmoving equipment operated by many people during his career and interacted with many companies on projects. Following the Carr and Dixie fires, where we lost our home and our family cabin, we again saw how various contractors approached and completed projects throughout our neighborhoods. Jesse Gorbet, Concrete Unlimited, and his crew are among the very best we've seen. Deft, nuanced, insightful, graceful, and considerate are not adjectives that normally come to mind with these types of projects but they do here. He was refreshingly excellent in communication, keeping us up to date, suggesting ways to save money and also setting up the project to make it easier for building in the future. Jesse was an absolute pleasure to work with, an unexpected gift. To have one contractor work with us to handle all these tasks themselves, and so professionally, was stress free. We highly recommend him."

Basement Waterproofing FAQs, answered by experts

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.
